It\u2019s been a few years. Thanks for making the time.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, it\u2019s great to see you, Tim. Yeah, we\u2019ve stayed in contact here and there with texting, but yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Lots of texts. And why not? This is one of the text threads I could probably actually make public in my life without some type of mutually assured destruction with many of my friends.<\/p>\n<p>I have been revisiting everything ketogenic and certainly looking at exogenous ketones for a number of reasons.<\/p>\n<p>And one of which we were chatting a little bit before recording, is that I have a number of relatives who are deteriorating from neurodegenerative disease, including Alzheimer\u2019s. And one of them is APOE33, and my siblings and I are APOE34, which would seem to indicate we would have potentially a, let\u2019s just call it two and a half X, higher probability of developing something like Alzheimer\u2019s, even though data might change. Who knows?<\/p>\n<p>Nonetheless, I\u2019m looking to throw as much possible at this from a preventative perspective. What data do we have, and if there\u2019s a little bit of speculation of all them, fine with that too in terms of future directions for research and what might come up for applications of, say, the ketogenic diet and, or exogenous ketones to something like Alzheimer\u2019s, whether it\u2019s from a preventative perspective, a mitigation of, or slowing of, progression of symptoms or anything else.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, that\u2019s a rapidly emerging area of research, and I think you\u2019re aware, we talked previously of the case reports that are out there that got put this on everybody\u2019s radar. I would say the early adopters of this idea were the people who understood that brain energy metabolism was pretty central to Alzheimer\u2019s disease.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Sometimes called type 3 diabetes, if I\u2019m getting that right.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. That was coined back in 2005 or \u20186, I think, and that was brought to my attention actually by Dr. Mary Newport and her husband, Steve Newport, was the subject actually in the case report for the use of the beta-hydroxybutyrate monoester for that. Dr. Richard Veech of the NIH was also on that. And Mary was near and dear to my heart. I actually coincidentally hosted her for dinner last night at the house and had her over here. And she\u2019s a close friend of mine. We co-teach together at USF. She\u2019s a guest teacher.<\/p>\n<p>Interestingly, I saw Steve Newport in 2008 or \u201909, and I witnessed the observation. He\u2019s a 3\/4. He has Alzheimer\u2019s. He was 3\/4 for APOE4. And he also had, he had Lewy body dementia, but confirmed Alzheimer\u2019s disease too when they looked at the brain. And I observed \u2014 I was still pretty \u2014 I was questioning this idea of ketones rescuing the brain in the context of Alzheimer\u2019s disease.<\/p>\n<p>Symptomatically, there was no doubt in my mind that it did, because I witnessed him. He wasn\u2019t using the ketone ester at the time, but we quickly transitioned to that after meeting, but he was taking coconut oil and MCT oil. And he would bring these little shot glasses. Mary taught my class. We went out to dinner. He did the shot glasses. His tremors stopped. He became animated, and he talked. And after about four hours, he started to decline and started getting fine tremors again. And then he would become reanimated upon increasing his ketones to about one to two, which we\u2019d give him a 30 milliliter shot of MCT plus coconut oil that was mixed in there. So she was really \u2014 and doing that three to four times a day with meals.<\/p>\n<p>So that was my first observation. And it was clear to me that there was at least a metabolic \u2014 within the Alzheimer\u2019s spectrum, I just like to \u2014 Alzheimer\u2019s is kind of a fuzzy diagnosis and \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Sure. Very fuzzy.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. And I just like to call it dementia, cognitive dementia. There\u2019s vascular dementia and there\u2019s A\u03b2 and tau. And my wife was working on tau at the Alzheimer\u2019s center when we met. She was working under a guy who studied tau. Then there was people there who studied amyloid beta, and there was the tauists and the beta. And there was an argument as to what was more profound.<\/p>\n<p>But a universal feature of Alzheimer\u2019s is amyloid plaque accumulation. But also now we know that glucose hypometabolism is central to that. And as we age, our ability to use glucose as an energy source decreases over time due to they thought maybe vascular reasons. But come to find out, it\u2019s really, it\u2019s a constellation of things, including the glucose transporter, the GLUT3 is on neurons. Pyruvate dehydrogenase complex, which is really the governor or the rate limiter of glucose metabolism in neurons. That\u2019s PDH, pyruvate dehydrogenase complex.<\/p>\n<p>And the production of \u2014 if you look at that protein for that decreases over time, as does the catalytic activity of that enzyme over time. So we know that. And then there\u2019s neuroinflammation, there\u2019s a vascular component. So all these things kind of contribute to metabolic dysregulation, but also a big driver is neuroinflammation.<\/p>\n<p>And I do believe, as does Dr. Mary Newport, who is the author of that paper with a case report and a number of other leaders in the field, including, I\u2019m blanking on his name, the chair of neurology at Harvard just gave an NIH seminar on infection as an etiological agent for Alzheimer\u2019s disease. So Epstein-Barr virus, cytomegalovirus, herpes simplex virus. We do know \u2014 yeah, HPV \u2014 know can contribute to things like \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>So we\u2019re probably talking about \u2014\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>\u2014 cancer.<\/p>\n<p><strong>Tim Ferriss: <\/strong>\u2014 if, I mean, 50, 60 percent of the population having one of these things.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Sure, yeah. Well, Steve Newport, the subject in that case report, had bouts of herpes, HSV, around the eyes and got hit pretty hard with that. But also people who have shingles that I think they\u2019re at risk too. We know Epstein-Barr virus, you\u2019re four or five times more risk for things like MS. It\u2019s triggering the immune system.<\/p>\n<p>So I think there\u2019s a renewed interest in looking at Alzheimer\u2019s disease, looking at the root cause. And I think metabolism is central, but the metabolic hit that may be contributing to dysregulated metabolism and neuroinflammation could be an infection. And I think there\u2019s accumulating evidence for that. I was skeptical 10 years ago, probably, when we talked. However, this kept putting on my radar. And then I was in an NIH sponsored workshop on this looking at various aspects, and the data presented by a number of different labs was very compelling for this.<\/p>\n<p>So what does that mean? Our immune system is \u2014 there\u2019s the four horsemen that our friend Dr. Peter Attia talks about. I think the fifth horseman is really the immune system. I like to add a sixth horsemen as our physical form, our skeletal structure, so our bones, and that will give over time too. But the immune system is really central to longevity. And the metabolic control of epigenetic regulation and metabolic control of immune system function is of very high interest. I know the Buck Institute has refocused on that, and many longevity clinics are now looking at that.\u00a0<br \/><strong><br \/><\/strong><strong>Tim Ferriss:<\/strong> What is your preferred device for measuring ketones these days?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>For publications, we\u2019ve used the Abbott Precision Xtra because historically we\u2019ve used that. However, when I recommend a meter to people, I generally recommend the Keto-Mojo device because that \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Keto-Mojo.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>\u2014 has the glucose ketone index. And so the glucose ketone index is the millimolar concentration of over ketones, and the strips are about, nowadays, still less \u2014 I was going to say, I don\u2019t know, a few years ago, they were about half the price. And we\u2019ve tested the Keto-Mojo. We have a human clinical trial where we did breath, we did urine, and we did Precision Xtra and Keto-Mojo all together. Then subjects go into the chamber and we did metabolomics and everything else. But the Keto-Mojo consistently gives us numbers that are more in line with our biological assays that we run in the lab.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Okay, interesting.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Like the [inaudible] on that.<br \/><strong><br \/><\/strong><strong>Tim Ferriss: <\/strong>Yeah, yeah. Let me just tell you what I\u2019m up to and you can tell me how ridiculous I am in off base or fact-check as needed. Can you remind me of how to pronounce this Dr. Thomas? Is it Seyfried? Am I getting that right?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. He\u2019s a good friend and colleague. Dr. Tom Seyfried.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Tom Seyfried. All right. So in terms of fasting, we\u2019ve talked quite a bit about fasting. It still is very interesting to me. And I\u2019m wondering just in brief, if you could, without getting too much in the weeds, but I\u2019m wondering what the ketogenic diet does that exogenous ketones do not achieve? And then I\u2019m wondering what fasting does that the ketogenic diet does not do.<\/p>\n<p>But the way I want to get to that is to ask you, because for a long time I was doing a one week, we could call it a water-only fast, but let\u2019s call it a calorie-free fast, right? Black coffee and black tea and stuff I was consuming, but a week-long, water long fast a year, and I was doing maybe a three-day fast every quarter. I didn\u2019t really want to do three to four week-long fasts a year, just didn\u2019t want to do it. But in terms of potentially purging precancerous cells and so on, I was like, you know what? I like the aesthetic practice \u2014 seems like a bit of autophagy and cellular cleanup is a good thing. Why don\u2019t I do that?<\/p>\n<p>Do you do any fasting anymore or is that something that you have omitted from the current version of Dom\u2019s schedule?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I do it situationally and I think there\u2019s situations where I think I\u2019ll benefit from fasting or from just inducing a state of an energy deficit. So you could do caloric restriction, time restricted feeding, dietary restriction. You could do a restricted ketogenic diet, a cyclic ketogenic diet, modified, a modified supplemented ketogenic diet, which is what I do. I like to do what I call, I mean I coined it. It\u2019s like sardine fasting. And I had a cancer patient a long time. One of the first that I sort of engaged with, actually his name was Dr. Fred Hatfield. So he was kind of a famous \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>This is Dr. Squat?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, yeah, Dr. Squat.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Back in the day. Wow.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, we were good friends. He was a mentor to me in many ways. But he had advanced metastatic prostate cancer, and it went to the bones where they did a PET. And I was just getting into this area of research and I was like, \u201cHere\u2019s what I would do.\u201d And I would go to his house and I\u2019d bring him things, and he was testing things. And he loved sardines. So I think he steered me onto sardines in maybe 2007 or oh eight or something like that. So that was my love for sardines was probably from him.<\/p>\n<p>But he would do low-carb. He called it ketogenic, but I think it was just more of a low-carb diet. And then he would do five days, he would do a fasting mimicking diet that Valter Longo has advanced, but he has more of a plant-based approach. But Dr. Hatfield would do, Fred would do one or two cans of sardines, maybe one can of sardine per day for a week. So we called it sardine fasting. And that was just as I was getting into this. And essentially what happened is that he went into rapid remission and the doctors didn\u2019t really know. Fred ended up passing away maybe eight years later of something completely unrelated to his cancer.<\/p>\n<p><strong>Tim Ferriss: <\/strong>As a non-oncologist, I have to pause and just say, I mean, it seems like prostate, for a lot of people, they hear that, they think \u201cDeath sentence.\u201d Metastasized prostate cancer, they think, \u201cNo way, you\u2019re done.\u201d Am I exaggerating? I mean, how frequent is it that people have complete remission of something like that? Maybe I\u2019m exaggerating things.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, there\u2019s a lot of factors like the Gleason score and his was not good in a number of factors. So he was given, I think he told me three months to live, but he went years and years \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Wow.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>\u2014 after that. And he was like, no evidence of disease.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>How often was he doing the sardine fasting? Was that once every month? What did his cadence look like?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, he stayed ketogenic, and then I would go over there and encourage him to do that, and he loved to do it. He was like, \u201cOkay, I do this and now I feel better when I\u2019m doing it.\u201d Fred also surprisingly, would smoke a little bit, and I got him to maybe stop that too. So we got him to dial back on some other behaviors and maybe he would drink a little bit too, but not that much. But his health improved dramatically when he adopted a low-carb and then ketogenic diet. And then for years, he did the sardine fasting and we communicated and I just encouraged, \u201cHey, keep sending me your medical reports.\u201d<\/p>\n<p>And I was like, \u201cMaybe there is something to this.\u201d So that actually steered me into just like the Alzheimer\u2019s, we did started Alzheimer\u2019s research because of Dr. Mary Newport. I studied seizures because of Mike Dancer. Just Google Mike Dancer, epilepsy, and you\u2019ll find some remarkable stories. I steered him to the ketogenic diet and it was a remarkable. He got off all meds and it worked way better than the meds. So Fred, but that was prostate cancer. But then I started engaging with other patients and then connected with Thomas Seyfried soon after that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>How frequently was Fred doing the week-long sardine fasts, if you had to guess?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Once a month. Sorry. Yeah, I meant to \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Once a month.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, it\u2019s analogous to the fasting mimicking diet. I think Valter Longo can do that. He advises patients based on, situationally, their situation. But I encourage Fred to do it every month. And his feedback to me was that he would do it once every month to two months. He enjoyed doing it, so it was something that he kind of looked forward to doing.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Sardine fast. I can\u2019t wait for that to become a thing. That\u2019s going to spread. I don\u2019t want to gloss over what you personally do. So for you, for instance, I found out recently \u2014 and everybody get your checkups. Do not skip colonoscopies. Do not skip. In my case, I got an endoscopy because I was having some trouble swallowing every once in a while. I thought it was like, ah, maybe it\u2019s just like I\u2019m eating too quickly with dried chicken or something. And suffice to say, putting that aside, that was sort of the symptom that catalyzed it.<\/p>\n<p>But I ended up having very unexpectedly a hiatal hernia. Hiatal, I think also related to the word hiatus etymologically. I\u2019m going to get the definition wrong, I\u2019m sure. But basically from your esophagus to your stomach, typically there\u2019s a nice kind of sphincter or ring, and basically the stomach is kind of pushed out of that ring. And there\u2019s actually a lot of scarring in my throat from acid. And so I was told that maybe not this bluntly, but that puts me at some increased risk of throat cancer or esophageal cancer, some type of cancer.<\/p>\n<p>And I was like, \u201cShit, that\u2019s not typically what kills people in my family. Usually it\u2019s the cardiac stuff.\u201d And I feel like I have that. My lipid profile is very well under control, which is why going back and doing research for this conversation, and I\u2019ve also done fasting over the years, I\u2019ve thought, \u201cOkay, well, in addition to taking the proton pump inhibitors and everything so that I\u2019m not accumulating more scarring, is there a place for doing the fasting, since I don\u2019t mind doing it anyway? Just to further hopefully decrease the risk.\u201d\u00a0<\/p>\n<p>And you were saying you fast episodically, was that the word that you used?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Situationally, episodically.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Situationally. Situationally. What does that mean?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>If my wife is traveling and it prevents me from being antisocial and I have a lot of work to do, and I have a grant deadline that\u2019s five days away, okay, I\u2019m starting fasting for five days until I get this grant submitted. If I\u2019m traveling by myself, I\u2019ll do it. Occasionally I\u2019ll get sort of an inflammatory flare up and I don\u2019t know what it\u2019s \u2014 I\u2019ll feel a little bit off like brain fog or my joints or something like that. It\u2019s pretty rare now because my HSCRP is like non-detectable, right? Before I did, it was always one or two on a higher carb diet.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So people might recognize CRP, right? I mean, C reactive protein is a marker of inflammation. I mean, if you get your annual blood test or whatever, chances are it\u2019s on there somewhere.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I\u2019d like to draw attention to that real quick because HSCRP is a better indicator of cardiovascular disease than LDL cholesterol. We know that now. If someone said that 10 years ago, they\u2019re just like, \u201cWe think you\u2019re crazy.\u201d<\/p>\n<p>But yeah, HSCRP is what we call a cardio metabolic biomarker, including triglycerides and insulin and things that should be included. But that is a really important biomarker, I think, to keep low for Alzheimer\u2019s and cancer and all the other, I call it six horsemen. No. The things that I mentioned. But yeah, so occasionally I will use it situationally just if I feel my body, if I feel like something is coming on, I\u2019m getting a flu. But the sardine fasting is, and I advise it for cancer patients too. I want them to avoid a water-only fast in the context to prevent cancer cachexia.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Muscle loss or muscle wasting.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. And omega-3 fatty acids are very potent mitigators of cancer cachexia. And so you have the omega-3s and basically you have everything your body needs, especially nutrition-wise in sardines. You might want to add a little bit of vitamin C or magnesium or something. But essentially it\u2019s like you have adequate nutrition and then you create a caloric deficit, you create caloric restriction, and then with caloric restriction come a whole host of beneficial things. The protein\u2019s low enough that you\u2019re suppressing insulin, mTOR, and probably activating AMP kinase. And if you do that in a protracted way and you can achieve a glucose ketone index of one to two for about three to five days, that the constellation of things that if you measure that would correlate with inducing and maximizing autophagy. So that was the rationale for me to do that. A lot of people talk about autophagy and it\u2019s kind of a nebulous term. We measure it. We look at the autophagosome. So we\u2019re a lab that actually does look at things like that. There\u2019s p62 and other things that you can measure, but there\u2019s no commercially available \u2014 I think the best way to measure to suggest you\u2019re in autophagy is a glucose ketone index after a period of fasting.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Which Keto-Mojo will do automatically. It\u2019ll do the calculation for you. I did have a quick question.\u00a0<\/p>\n<p>When I compared my Keto-Mojo to an oral glucose tolerance test where I was having blood drawn every 30 minutes, the glucose readings I got from the Keto-Mojo were substantially higher than the blood test, than the blood draw itself and I was wondering if that\u2019s something you\u2019ve observed. I mean, who knows? Maybe it\u2019s a bad device. Maybe I had too much alcohol still on the finger and I didn\u2019t dry it properly. I mean, who the hell knows? Maybe it doesn\u2019t matter so much, but it seems to matter because regular spikes above a certain nanogram per deciliter seem to be indicative of all sorts of things. Have you run into any issues with the device or any caveats related to specifically the glucometer side? What I do like that\u2019s nice about it is it does give you that glucose ketone index, the GKI as a readout right there on the device or in the app at least that accompanies the device.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Are you talking about measuring glucose at the exact same time point that a phlebotomist pulled blood.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s exactly what I\u2019m talking about. Yep.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Okay. What was the difference between what was measured there?<\/p>\n<p><strong>Tim Ferriss: <\/strong>Let\u2019s say the peak at 30 minutes out after drinking this not-so-delicious dextrose water. It\u2019s something like this. I was bumped up to probably 140 on the phlebotomist drawn blood and it was like 165 on the Keto-Mojo. The return was much faster and much better on the phlebotomist drawn blood than it was on the Keto-Mojo device, which not to throw them under the bus. It could be operator error or just a single bad device. I have friends who have used it very successfully on the ketogenic diet, which is why I ended up buying it because Precision Xtra is kind of a pain in the ass to get a hold of, at least on Amazon. So that was my experience and I was like, \u201cOkay. Well, tricky, tricky, tricky,\u201d because if I\u2019m really trying not to pop above a certain level, if the device I\u2019m using day to day is 20 points above where maybe it should be, then that\u2019s a problem.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>What\u2019s your hemoglobin A1C?<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019d have to go back and look. It\u2019s trending down, but I would have to go back and look.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>If you wear a CGM, you\u2019re under maybe 100 with the CGM. So the meters tend to trend a little bit high, about 10 percent high. I think they were 10 to 20. Keto-Mojo was 10 percent higher than our assays, and the Precision Xtra was 20 percent higher than the assays that we do when we pulled blood from the animal. So if that helps, I think you want to at all. You want to look at your insulin levels, your hemoglobin A1C, hs-CRP.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, we got it all. Just for people, public service announcement, do an oral glucose tolerance test, ask your doctor, talk to them, get your insulin measured, because my relatives metabolic dysfunction was missed for a very long time, in part because they were looking at fasting glucose. You can get really lucky with fasting glucose depending on when you get that snapshot and the docs weren\u2019t great to begin with who were tracking these relatives, but as soon as we looked at OGTT, the oral glucose tolerance system, insulin, oh my God, it was like sky-high out of range.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Or put a CGM on them. That\u2019s what motivated me to be, I guess, one of the first advisors for Levels. I\u2019ve worked with them on a research front. I think you\u2019ve interviewed Sam, right?<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>But Levels, I mean, that\u2019s \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, Sam Corcos.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, Sam. I mean, that\u2019s like the ultimate kind of metabolic optimization platform. I mean, there\u2019s others emerging too, but simply wearing \u2014 I mean, now they have the Stelo device that came out, so CGM\u2019s are over-the-counter now, but the analytics from that and also the biomarkers that if you\u2019re part of that program that you can measure, which include many things that we could talk about, but that would capture your relatives if your relatives put a CGM on. That\u2019s really important, but what you observed is pretty normal and not to probably be of concern, like your \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Okay. Cool. Yeah, I just wanted to check it out. Just to tie this up for me, and I maybe just missed it, if someone is using ketones on a continual basis, are there longer term adaptations? Part of the reason I\u2019m asking is that in the most recent set of experiments, let\u2019s just say, I was strict keto for three weeks, and then frankly just got bored to death of the diet.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>It\u2019s hard.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, I did three weeks of let\u2019s just call it kind of textbook \u2014 protein also quite low, like 10 to 15 percent let\u2019s say, so maybe I bump it up next time, but just got so bored of it after three weeks, but I want to do enough that there might be some upgrade of the metabolic machinery. We could talk about that because I know for athletes it might be like six months to 12 months, but went from that to then 16:8 intermittent fasting, still in ketosis for maybe a week, so 16 hours off eating between, let\u2019s say, 2:00 p.m. and 10:00 p.m. Then I went to a more paleo-ish diet, let\u2019s just call it, within that feeding window. Then I did that for a few weeks and then started layering in exogenous ketones in my fasting state, typically 11:00 a.m., 1:00 p.m. if I\u2019m doing podcast recordings and things like that.<\/p>\n<p>Part of what I\u2019m trying to figure out is given I\u2019m APOE3\/4, scared to death of Alzheimer\u2019s, and maybe there\u2019s nothing to be done about it, but if there is something to be done in addition to exercise rights and kicking out the Klotho and BDNF and all that good stuff, from a dietary perspective, trying to figure out, okay, how long does keto memory last if there is an expiration date? If you were in my shoes, how you would think about not just the exogenous ketones, but fasting and ketogenic diet? Do you have any thoughts on that?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Well, yeah, you\u2019re doing a lot of stuff there, and I would recommend following a protocol that you could do day in and day out that should ideally almost be effortless and mesh with your schedule, which may be variable if you have podcasts and things like that. I\u2019m of the opinion that you could follow a baseline diet, which is a low-carb Mediterranean-like diet. Mediterranean is kind of a fuzzy term, I hate it, but low-carb Mediterranean style diet that essentially keeps biomarkers in check and then situationally going the ketosis now and then to just optimize it. But you want to follow an approach therapeutically that keeps your GKI into that one to four range. Tom Seyfried is very adamant about one to two, but the normal GKI of a person in the US is like 50, or 25 to 50.<\/p>\n<p>So just living in a state of having a GKI of even five would be, I think, trending towards being more metabolically flexible and having greater fat oxidation. Then you want to, as it sounds like you\u2019re doing, just keeping check of your metabolic biomarkers, so comprehensive metabolic panel, CBC, of course, if you\u2019re using different agents on that, but insulin HSCRP, hemoglobin A1C, triglycerides, ApoB you want to measure too, Lp(a) it\u2019s good to know.\u00a0<\/p>\n<p>Unfortunately, 30 percent of people \u2014 this is probably important when navigating what protocol to use. I have a mutation. I did GB HealthWatch, which looked at my genetics for dyslipidemia. So GB HealthWatch, Dr. Spencer Nadolsky reached out to me because I was posting my numbers online and he was like, \u201cHey, you need to do this test.\u201d He\u2019s a very smart, aggressive or proactive kind of guy and suggested this test. He\u2019s like, \u201cI think you\u2019re a hyperabsorber.\u201d I was like, \u201cIsn\u2019t one percent of the population hyperabsorber?\u201d But come to find out about 30 percent of the population hyperabsorb cholesterol.<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s me too. I\u2019m in the same boat.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Okay. I have an NPC1L1 receptor mutation that\u2019s a gain-of-function mutation. I use an ezetimibe monotherapy for that. Ezetimibe was sold as Zetia, and I can get by with half of a tablet, which is five milligrams, and half my ApoB. It put my ApoB \u2014 it cut it in half, and also half my LDL. So I can follow a ketogenic diet. I had the skyrocketing LDL ApoB, but then I put that back in check. I am of the opinion that I need more data to come out. There\u2019s a group of people that think LDL in the context of optimal metabolic biomarkers that it\u2019s not to be concerned about, but that data is emerging and there\u2019s groups of people that I believe are credible and then working on that front, looking at the lipid energy model. With the lipid energy model, LDL and ApoB is a carrier for fat to peripheral tissues, but we don\u2019t have to go there.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Dodge it for now.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. If your LDL pops up, then a pescatarian Mediterranean-like diet that\u2019s low-carb that\u2019s ideally under 100 grams of carbohydrates per day, and that\u2019s no sugar, no starch, fibrous vegetables and fruits. So my rule of thumb is 25 percent of what carbohydrate you consume should be fiber, and then that\u2019ll essentially make it non-glycemic, right?<\/p>\n<p><strong>Tim Ferriss: <\/strong>What percentage did you say?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>What I do personally is about 50 to 100 grams of carbs a day and ensuring that the carbohydrates that you\u2019re consuming, about 25 percent of that carbohydrate is fiber, so for example, broccoli, asparagus, of course, cauliflower, green, leafy vegetables, but even fruits, I trend towards wild blackberries, raspberries, blueberries, and buy them in combination. Then wild blueberries are about half the size and they have more fiber, less sugar, so I have a cup of that per day. My carbs come from mostly broccoli, wild berries, dark chocolate, and maybe a few other odds and ends.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Where do you get wild berries? Is that something you buy or do you have to go out and steal from your neighbor\u2019s patch?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Well, yeah, we have a blueberry \u2014 surprisingly, blueberries grow great in Florida \u2014 but we have a blueberry farm right by us. It\u2019s a winery, so they grow blueberries and then make blueberry wines and things like that and have huge festivals, but we get from there. But yeah, you can go to Walmart and get the Walmart blueberries, which are the size of grapes. Then next to that, now Costco and Sam\u2019s and even Walmart now have the wild blueberries.<\/p>\n<p><strong>Tim Ferriss: <\/strong>No kidding? Okay. Just because you mentioned LDL, I might be hallucinating this, so please correct me if I am, but didn\u2019t you at one point dramatically cut down your LDL labs by swapping dairy out, I think maybe heavy cream and using coconut cream or something else in its place, or am I making that up?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I took out heavy cream, but put sour cream back in, but maybe about half of the sour cream, but also just switched out the eggs. I think the eggs were getting to me because eggs have a lot of cholesterol, and I was eating a dozen a day.\u00a0<\/p>\n<p>When I prepare my food in the morning, my dogs get my food. So I\u2019ll make 10 eggs, but I\u2019ll have three yolks, and then I divide the other yolks between my two dogs. Then instead of ground meat, which I was eating a lot of, I get chub mackerel. I do sardines, occasionally tuna fish, but I get cases of chub.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Chubb like the insurance company, C-H-U-B-B? No. How do you spell that?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, C-H-U-B. Unlike a king mackerel, which are bigger, chub mackerel are small fish.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, don\u2019t bioaccumulate as much garbage or \u2014\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. So they\u2019re really low on the heavy metal list, which I tend to check because I eat so much of it. One can is almost a pound, and there\u2019s three fish in each. I take a fish and give my two dogs each a fish. It\u2019s got a lot of fatty water in it full of omega-3s, and I pour that on their food and they love it.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Where do I sign up to be reincarnated as one of your dogs?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, this morning they got \u2014 my wife has an Audacious canine supplement, so we give them a \u2014 that\u2019s got spirulina, ketones and a few other things. We give them that, creatine monohydrate.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Hold on, I can\u2019t skip over that. Why give ketones to your dogs?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Well, the brain-boosting effects, the anti-inflammatory effects, the neuroprotective effects, and the anti-cancer effects, so these are all things I worry about with my dog. They are fixed. I do give them a SARM, surprisingly, after they got injured.<\/p>\n<p><strong>Tim Ferriss: <\/strong>This is an anabolic, right?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I do, yeah. I transitioned. They got attacked by a big pit bull and they kind of immobilized for a while. I was going to use it for a cancer cachexia study, and it\u2019s ostarine, I think. So I started giving it to them and it seems like they are leaner, stronger. We have a Great Dane that\u2019s 12 years old. That makes him 90 to 100 human years, and he runs 35 miles per hour. He has no sign of slowing down.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, he\u2019s a Great Dane that should have passed away years ago and he\u2019s just like a machine.\u00a0<\/p>\n<p><strong>Tim Ferriss:<\/strong> You mentioned Audacious Nutrition. Just for the purposes of transparency, you do have family in the business involved with Audacious, right? Just to confirm?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino:<\/strong> Yeah, I can\u2019t have any company. I don\u2019t sell anything personally, but my wife decided to create a product that used the ketones that we actually used in research. So it evolved out of that was various salts, and the idea was that if that product was created, then we can use it for research. And that was the initial part.<\/p>\n<p><strong>Tim Ferriss:<\/strong> Cool.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I was using it anyway. I was like, \u201cWell, why don\u2019t you just make a product out of this? I can\u2019t do it.\u201d But it actually was an I-Corps NSF program through the university that got that started.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Question, do you give rapamycin to your dogs or to yourself. Do you currently take or give your dogs rapamycin?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I\u2019ve gone back and forth. I follow Matt Kaeberlein\u2019s work pretty closely and go back and forth. I\u2019ve decided not to just because of the immune suppression. I know I got about a handful of people that use it, and I would say half of them get sores in the mouth. That can\u2019t be a good thing.<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s super, super common, the mouth sores.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. The data\u2019s too early for that. I think the same thing can be achieved in a greater \u2014 a bigger lever would be sardine fasting for one thing and just beta-hydroxybutyrate and well-formulated low-carb supplemented ketogenic diet, by definition, a diet that elevates ketones and exercise, so exercise and a whole host of other lifestyle things. I\u2019m not ready to pull the rapamycin trigger on my \u2014 anything I do with my dogs, excluding the SARM, I haven\u2019t used that, but seeing the effects and looking at their blood work, it looks perfect. So there are no side effects with that and it seems to be helping with their advanced age.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Can you take just a paragraph, explain what this SARM refers to for people?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, there\u2019s a specific androgen receptor modulator that hits the androgen receptor but doesn\u2019t have the androgenic-like qualities.<\/p>\n<p><strong>Tim Ferriss: <\/strong>It\u2019s not going to give you a third Adam\u2019s apple, but it\u2019ll help with muscle growth.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>It helps to stimulate skeletal muscle protein synthesis, and then the context of this drug also bone metabolism. Both of our male dogs are fixed too. We have discussions with various vets that are of the opinion \u2014 they\u2019re more progressive that your dog should be on like TRT or testosterone if they\u2019re fixed, because that will increase the quality of their life, especially as they age. Our dog look \u2014 I can\u2019t detect any loss of skeletal muscle mass even when I look at pictures \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>For clarity, your dogs are all male?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, we have two male dogs and both of them are considered advanced age, and the black Lab is showing it a little bit. He has hardware in his two back legs. We had two knees put in with him, but he was a little bit heavier and now we\u2019ve dropped his weight with what I feed him now, which is essentially fish, meat, eggs, ketones, and we give him a mushroom supplement. That\u2019s a mushroom kind of lion\u2019s mane and a reishi, maybe cordyceps and a few other things, and then I give them creatine monohydrate. Yeah, they\u2019re pretty optimized as dogs. I think the big thing is that we live on a farm and they get a lot of activity too. They get two non-negotiable walks every day. I do that for me too. That\u2019s part of my creative downtime is to do a non-negotiable walk morning and night. So they get a lot of that and they chase our animals around too.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What are your current feelings on \u2014 let\u2019s just say on the sardine fast, when you\u2019re doing a week-long sardine fast, and maybe you\u2019re so adapted at this point that you don\u2019t experience this, but certainly when I\u2019ve done water fasts, and even if I\u2019m following a lower calorie ketogenic diet, I can have a really tough time sleeping, at least for a handful of days, right? I have just rapid heart rate. I don\u2019t know if that\u2019s trying to compensate for lower blood pressure because I\u2019m just losing so much water and electrolytes. Who knows? I have found supplemental electrolytes to help a bit with that. But what type of supplementation do you take or advise people take if they are trying a ketogenic diet for the first time or fasting? Maybe the answers are different. Let\u2019s just say it\u2019s a sardine fast like, man, Valter Longo coming for you with a sardine fast. What supplementation makes this easier or more productive just from an adaptation perspective?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I will use sardines and also KetoStart, which is essentially the electric sodium, potassium, calcium, magnesium, beta-hydroxybutyrate and that will be used two to three times per day. At nighttime, when you go with a caloric deficit, your sympathetic nervous system is activated a little bit, especially with the water-only fast, so you get a little bit hyper or dysphoric even for some people.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, I feel like you just ran up three flights of stairs when you\u2019re trying to go to sleep. Yeah, it\u2019s unpleasant.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Yeah. So that\u2019s less with a sardine fasting instead of zero calories. So the sardines would then be eaten at nighttime typically. I remember doing this repeatedly, and what I would do is take a little bit of GABA at night, and on one or two fasts I took just 25 milligrams of diphenhydramine.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I think that\u2019s the exact or close to the exact dose of one or two Benadryl, right? I\u2019d have to look at it, but isn\u2019t diphenhydramine Benadryl?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, diphenhydramine is \u2014 yeah, it\u2019s a histamine. It\u2019s tends to be lipophilic, which means when you take diphenhydramine, it quickly crosses the blood-brain barrier. You could be a little bit groggy the next morning. The studies show that 50 milligrams of diphenhydramine can decrease memory recall if taken acutely, but 25 milligrams, there\u2019s no effect of that. I\u2019m comfortable with taking 25 milligrams of diphenhydramine at night and then giving a lecture the next day in the morning. I feel razor sharp and because also it enhances \u2014 it reduces sleep latency, so I get better sleep, but I would not use it more than once a month or something. Yeah, I do think diphenhydramine and these over-the-counter sleep aids used every night by various people that are emailing me, I mean, it\u2019s creating dementia, I think. I mean, the data\u2019s pretty clear on that. You have an older person getting 50 milligrams every night, every week is bad.<\/p>\n<p>So melatonin, magnesium, a small dose, I guess for my size, it would be a half dose of diphenhydramine, and then GABA. So you could take GABA in the form of GABA that you can get over the counter, or there\u2019s also phenibut GABA, which I have but tend to haven\u2019t used in a while.\u00a0<\/p>\n<p>Phenibut I would just want to put out there can be a really nasty drug for people. It could be addictive. You build a tolerance real fast, and coming off of phenibut can be very problematic for people. I mean, it\u2019s like coming off of GHB, I think, but it could be a tool in the toolbox because \u2014 I mean, we\u2019re talking about taking two, three grams of phenibut can give you euphoria.<\/p>\n<p>It\u2019s like a benzodiazepine, kind of, but if you take 250 milligrams or 200 milligrams of phenibut, which is a small dose \u2014 I mean, theoretically, you could take that two or three times per week and never really build a tolerance or get, but I would not advise people to do that. But if you\u2019re going to fast, say, once a month, one way to avert that, and I get the same exact thing, I get super hyper and my brain just goes on fire when I do the first day of fasting, a little bit of GABA or phenibut, diphenhydramine, magnesium. I\u2019ve always done melatonin, five to 10 milligrams of melatonin.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Oh, that\u2019s a solid dose.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, we went on vacation and I forgot it.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Do you still use melatonin continually? Because I remember there was some conversation floating around the ether and never looked too closely into it because I don\u2019t use melatonin all the time about some possibility of endocrine disruption, or can you speak to that?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I\u2019ve been using melatonin probably when I started using creatine in 1993, the old phosphagen when I was in high school.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Back in the day.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. EAS is that way back in the day?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I was a beta tester for that. Yeah, I was a beta tester when phosphagen came out. Then 1993, I think I started using creatine. I was an early adopter of creatine. But to get to your question in melatonin, I studied melatonin on the hippocampus on brain slices. You can slice the brain like a piece of bread and applied melatonin, looked at reactive oxygen species and things like that. We used it for oxygen toxicity. It wasn\u2019t good for that because it did make the rats sleepy. Melatonin doesn\u2019t really make me sleepy, it makes me more calm than anything else. I went on a vacation where I forgot melatonin and I slept like a baby probably because I was up every morning. The sun is the ultimate circadian synchronizer. I got off of melatonin to check my endogenous melatonin, and there was no suppression. Melatonin in animals that are hibernating, like little gerbils and things like that, if you give them melatonin, it can suppress endocrine function including testosterone production.<\/p>\n<p>Huberman talked about it. I love Huberman. So I was following him and he was talking about melatonin. So I went to the primary literature and I was like, \u201cMan, he\u2019s right. It is an endocrine disruptor and suppressor.\u201d But then I dug into the literature more and it was not the case for humans. So there was no evidence in human. I think when he talks about it, I don\u2019t think he references a human study, but he does reference legit studies. Yeah, Andrew Huberman is an amazing scientist and he puts out awesome information out there, but it did get me concerned about it. So I got off of melatonin, and then I confirmed that my body does make normal amounts of melatonin, so I measured that. I also confirmed that five milligrams of melatonin, if I go and measure the next day, my melatonin is off the charts, meaning that I take five milligrams at night, the next day in the morning at nine o\u2019clock or 10 o\u2019clock in the morning, my melatonin is super physiological.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Is that good or bad?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I think it\u2019s good. So I take melatonin not to sleep, but as a neuroprotective agent that has a whole host of beneficial effects for the brain, also Alzheimer\u2019s disease and also cancer, especially breast cancer. So, use it for that. I also mega-dosed 20 or 30 milligrams and then checked my LH and FSH.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Milligrams?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Okay. Yeah. 20 to 30 milligrams.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>10 milligram tablets are like the gorilla tablets for melatonin. So I chewed a bunch of them and then held it under my tongue and I didn\u2019t really feel any more sleepy. I just slept like normal. My aura ring was normal. But then I went and I got lab work done and I did testosterone, LH, FSH, and there was no suppression. Actually, my LH and FSH were trending high end of normal, which is another topic that I can get into. But the thing is that it did not trigger an endocrine response in me. I do not think there\u2019s any data in humans, although specific animals are very sensitive to melatonin, and if you give it to them, it can cause endocrine suppression, some sex hormones. So it is a hormone. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Okay. All right. Well, that\u2019s good to know because I actually benefit from taking melatonin, but I largely cut it out because of some of the murmurs, but it does help me sleep. Is this a true statement that you do not do any fasting currently or recurrent pure water fasting, but instead do this situational sardine fasting? I mean, is that sort of 99 percent of the bang for the buck and there isn\u2019t really any reason to go beyond something like that as a fast-mimicking diet, or are there benefits that you think are compelling of doing a more restrictive, say, water-only fast where you\u2019re allowed black coffee and a few other things perhaps, but are otherwise really not consuming calories?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>For me, personally, it\u2019s very context dependent. I was talking to someone the other day that was getting shingles. As soon as the first sign of tingling, which is the precursor of getting shingles, they start fasting and it never actually surfaces. So only when they situationally pull the trigger and start water-only fasting does it completely mitigate \u2014 it\u2019s a massively effective countermeasure for herpes simplex flares or things like that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, I was going to ask, I don\u2019t know anything about shingles, so what\u2019s happening there? Do endogenous ketones, and therefore, could you just take a bunch of shots of exogenous ketones, or what\u2019s actually happening to have that suppression?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I think we\u2019re augmenting metabolic control of immune regulation in the context. You have the innate immune system, which is always kind of running around. Then research work we\u2019re doing now with the Moffitt Cancer Center is basically using ketone metabolic therapy to augment the adaptive immune system. So the adaptive immune system is more specific. It\u2019s kind of like that B-cell and T-cell, augmenting the B-cell and T-cell, things where it\u2019s like the adaptive immune system is like the Navy SEALs of \u2014 there was a human study that used a vegan diet versus a ketogenic diet, and this got put on my radar by numerous people who then wanted to research this. A vegan diet actually augments and enhances the innate immune system and a two-week ketogenic diet, and this was published in <em>Nature Medicine<\/em>, augmented the adaptive immune system and partly through the gut and partly just through changing metabolic physiology. This happens when we fast. If we\u2019re fasting, our gut is relaxing. I think it\u2019s restoring or preventing. When we eat something, we have things going into circulation that\u2019s keeping our immune system kind of active, right? So if we\u2019re not eating anything, our immune system becomes hypervigilant and then in a way that it becomes hypervigilant to attack things, but at the same time, it\u2019s suppressed.<\/p>\n<p>So inflammatory markers go down and because the immune system is like an army, you have a hundred thousand guys in an army in the immune system and they\u2019re all working if you\u2019re eating and you\u2019re stressed and environmental toxins and things like that. When we fast, we allocate more of that immune system to be more vigilant to attack things. But at the same time, our general inflammation state goes down. It becomes more vigilant, but inflammatory cytokines, chemokines kind of go down.<\/p>\n<p>So I think that\u2019s part of it in that it\u2019s stimulating, I think cancer-specific immunity but also just generally suppressing inflammation. And that\u2019s happening for a number of different reasons. In part due to elevating beta-hydroxybutyrate, which is an endogenous metabolite that plays a role in inflammasome suppression.<\/p>\n<p>So I know guys, maybe Eric Verdin and like the guys at the Buck Institute, they had kind of looking at that. And then our colleagues, Dr. Deep Dixit at Yale, sort of formulated a diet to specifically elevate BHB because he had showed previously that fasting suppresses the NLRP3 inflammasome and the metabolite that\u2019s off the charts with beta hydroxybutyrate. So the next study was giving that as a supplement with a normal diet to see if that could then also suppress the inflammasome and it did. And that was published in <em>Nature Medicine<\/em>, 2015.<\/p>\n<p>So I formulated the diet for that study and I\u2019m a middle author on that. So I think that plays a role in that. But I think it\u2019s multifactorial and I think it\u2019s just one of these things that needs to be studied because it\u2019s kind of universally accepted. It\u2019s kind of happening, but you also have to be in a good, healthy state.<\/p>\n<p>If your nutritional status is low, it depends on your baseline characteristics, your therapeutic response to fasting, and I think that\u2019s really important, especially for people who have cancer, maybe getting chemotherapy where they have compromised nutritional state in some ways, then you have to approach it very cautiously.<\/p>\n<p><strong>Tim Ferriss: <\/strong>How many meals per day do you eat now? How old are you, Dom, at this point?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>50s. Yeah. I just turned \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. 50s.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>In my 50s. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. Well, congrats. What does your diet look like now? Just kind of the set it and forget it version of Dom\u2019s diet. What does that look like?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. It\u2019s situational, but always probably three meals per day that I do and I did \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>And you weigh about how much at this point?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I just did a DEXA this weekend, actually. I did a DEXA two weeks ago and I did another one after I got off creatine and then did another one. So I just hover right at 218 to 220 and body fat last was 9.4 so \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. You got some muscle to feed. All right. So three meals a day. What does it look like?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>This morning it was eggs and chub mackerel and that\u2019s it. So basically just protein and fat. And for lunch, I typically have beef, chicken, or fish, usually fish. Lately I\u2019ve been eating a David bar. So Peter sent me some of those and I have kind of mixed opinions about it. It pops up on the CGM a little bit, but I think it\u2019s kind of an interesting direction to go into. I enjoy them, they taste really good. So I\u2019ve been doing that.<\/p>\n<p>And then for dinner, we went out for Mexican the other night and last night hosted Mary Newport and usually have beef, chicken, or fish with a vegetable, like always broccoli. I\u2019m a huge fan of broccoli. It worked. I could eat three pounds of broccoli has no gas or bloating effect for me at all. So somehow my body is just broccoli. My body loves broccoli, so our dogs do too. So I give them a little bit of that, salads, but usually about a pound of beef, chicken, or fish at dinner. So that\u2019s my big meal.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Wow.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>And over the years we have transitioned. Instead of eating at 7:00, we eat at 5:00 \u2014 5:00 or 5:30, so we eat earlier. And then I do physical activity after that. So if it\u2019s squats or deadlifts, I have to do it before I eat. But for pressing movements and activity, I do after that. And I do farm work for an hour or two in the evening after that.<\/p>\n<p>And I typically have, every other night, wine. So I\u2019ll have a bit of wine, lower alcohol, non-sugar Dry Farm wines, which has less than one gram of sugar. I would never drink wine without doing some kind of activity after. If wine at nine o\u2019clock and then try to go to bed, I would never do that because I see that on my aura. But if I do a glass of wine in some form of physical activity, we always do an evening walk. I think I sleep better, I think.<\/p>\n<p>I don\u2019t do two glasses, but I just do one glass. I know the current consensus on alcohol is that it\u2019s \u2014 but I would push back because none of that is specifically studying wine. If you go to the studies on wine, actually, shows once, the first one that came up is actually decreasing cancer risk.<\/p>\n<p>And then I noticed that when I take wine and measure my blood, it\u2019s less viscous. So wine also decreases platelet aggregation. So it makes your blood less viscous. And that is well known. I observed it and was like, \u201cSomething\u2019s going on here.\u201d And then I went to PubMed and it\u2019s actually well known. I didn\u2019t know it at the time that it decreases platelet aggregation, so less potential for clotting, for stroke and things like that.<\/p>\n<p>So I think that may factor into \u2014 we just got back from Greece and they had the ouzo and everything, then we went to Sardinia. So we went to these blue zones and they just, at night after their dinner, the males will do a shot of alcohol, usually wine, but sometimes ouzo and they\u2019re all in their 90s and hundreds, they\u2019re in the blue zone. So it\u2019s a universal characteristic. That\u2019s my protocol.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, there may be a genetic component too. I remember there was this book that was like, <em>Why French Women Don\u2019t Get Fat<\/em> or something and way back in the day, I remember before his passing, I was talking to Charles Poliquin, he\u2019s like, \u201cYeah, MTHFR.\u201d He is like, \u201cThat\u2019s why. It\u2019s none of the other stuff in the book.\u201d And he mentioned a couple of other things, like, who knows? I think \u2014\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Living by the water, activity, and social. So the social interaction is probably the biggest lever. I mean, I just see them, they\u2019re all out and about walking around and yeah, that\u2019s probably the biggest lever. And getting sun. So they\u2019re outside in the sun, everybody, it\u2019s multifactorial, but it doesn\u2019t seem to be hurting them, let\u2019s put it that way.<\/p>\n<p><strong>Tim Ferriss: <\/strong>If someone is, let\u2019s just say they want to test out the ketogenic diet, and certainly they will note, they\u2019ll be like, \u201cWow. Dom doesn\u2019t eat a lot of vegetables except for a pound of broccoli at dinner \u2014 \u201c<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I can tolerate that but I have, probably it comes out to 30 to 40 grams of fiber a day, which is pretty high, but that\u2019s broccoli. And I usually have a small apple too. Sometimes we have apples and then a cup of wild blueberries. So it comes out to about 30 grams. That\u2019s maybe a higher, sometimes 10 or 20 but I try to shoot for about 30 grams of fiber.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Got it. Okay. If people want to kickstart the ketogenic diet, any tips for getting over the hump in the beginning? It can sometimes have a bit of a hard time before they kind of click over. I\u2019m not sure. For me, it\u2019s like once I\u2019m above 1.2 millimolar I feel totally fine. That\u2019s just me on a Precision Xtra. But for people who are looking to give it a shot and maybe haven\u2019t given it a shot, any tips for novices?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. I would do fasted low-intensity cardio. For me, that would just be going for a long walk. Waking up in the morning, and if you\u2019re going to start your ketosis experiment or whatever you\u2019re doing that morning, getting out in the sun, staying well hydrated, you could take MCT and also ketone electrolytes like KetoStart or something like that. And then that will ease the transition because it takes a little while for your ketogenesis to ramp up due to you got to deplete liver glycogen and ramp up beta oxidation fat enzymes.<\/p>\n<p>And then as ketones get into circulation, over the period of a couple weeks, you\u2019re going to upregulate the ketolytic enzymes, which are basically the enzymes and the tissues that are able to utilize and leverage those ketones for energy over time.<\/p>\n<p><strong>Tim Ferriss: <\/strong>How long does that adaptation take, would you say?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I don\u2019t know if anyone has unambiguously answered this question in humans, but in rodent models you could see the MCT transporter, not to be confused with MCT oil, but the monocarboxylic acid transporter, now there\u2019s one, two, three and four. That protein is 50 percent higher after two weeks in a rat, for example.<\/p>\n<p>I think the point for most people is that if you start fasting or ketogenic diet and to avert the keto flu, you want to hydrate, get in electrolytes and also elevate ketones as much as possible. And to do that with MCT, if you can tolerate it or ketone electrolytes. I would not be guzzling a ketone ester because you\u2019re going to spike ketones up, you\u2019re going to inhibit your own ketone production, especially if it\u2019s a dose-dependent thing. But my advice would be low intensity cardio, hydrate electrolytes, and then small amounts of ketone electrolytes with MCT. So MCT will stimulate your own Ketone production too so it kind of \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Now are you just taking tablespoons of liquid MCT? Are you using a powder and mixing it in? What do you personally do or what would you recommend?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>For the liquid, sometimes what I do if I\u2019m eating tuna fish, which is packed in water. I\u2019ll pour the MCT on the tuna fish and stir it up and then deliver it that way. If I\u2019m having coffee, I can put in the MCT powder in the coffee and mix that up and that would be 10, 20 upwards of 30 grams and work by Stephen Cunnane actually showed that if you take MCT in the context of caffeine or coffee, you can boost your ketone production by 20 or 30 percent. So there\u2019s a bit of a ketogenic synergy when you deliver caffeine with MCT. It\u2019s stimulating lipolysis and also fat oxidation in the liver so you\u2019re ramping out \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>What type of powder do you like to use?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>People send me things but actually the powder that I have is actually, it\u2019s Keto Brainz. It\u2019s MCT powder, Alpha GPC theanine, and it has lion\u2019s mane mushroom. So it goes under the brand name of Keto Brainz, and that\u2019s the MCT powder that I use. The base of it is MCT, but then it has sprinkled onto that theanine, which has a nice calming effect, which probably good to use on the first day of fasting. Alpha GPC, if I take too much of it gives me a headache so I only do one or two.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. I got to be careful with Alpha GPC. I also get a headache.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Oh, really? Okay.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>So you\u2019re the first one. I don\u2019t know if I was creepy. But yeah, when I first got Alpha, when I first got Keto Brainz and did like six scoops and I was like, \u201cOh, my God. I got to have a bad headache.\u201d But one or two scoops.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I love that your first go was six scoops. If I just want it off the shelf, MCT oil, because I feel like there\u2019s only so many medicinal mushrooms that I can cram into my diet also, but no offense to the mushrooms, but I actually have some interesting thought on some of them additional mushrooms. Some of them are very strongly antiviral and immunomodulatory. And so when I\u2019ve talked to a number of very credible mycologists, so like, \u201cYeah. It\u2019s probably best not to take that stuff every day. You should cycle on and off.\u201d<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>But if I just wanted MCT, for purposes of travel, because MCT liquid can create such a goddamn mess when you\u2019re traveling.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>And their pants too. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And in your pants too. And for people who are novices do not do creatine, caffeine and MCT oil out of the gate. You\u2019ve got to prove to yourself that you can handle that.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Unless you\u2019re constipated.<\/p>\n<p><strong>Tim Ferriss: <\/strong>It depends on the airplane. Yeah. What other just MCT oil, powders might you recommend or have you used?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Quest MCT powder. I think you can get that in like CVS and Walgreens now too. And Amazon, just the Nutricost. So I bought just straight up MCT. They also have a C8 powder and I\u2019ve tested both of them wearing a continuous ketone monitor. And I saw a nice elevation over time and then I combined that MCT powder with KetoStart, and basically I was in ketosis for half the day. So just dosing twice a day with that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I mean, I\u2019m going to break my own rules here, but I\u2019ve done enough test drives. I\u2019m about to go to, not super high altitude, but I\u2019ll be coming from sea level to about 8,000 feet on average and we\u2019re going to be doing a lot of intense exercise. So maybe my morning dose of coffee, which I\u2019m sure will be some shit instant coffee, but it\u2019s going to taste delicious when you\u2019ve been freezing your balls off all night, maybe I\u2019ll add some KetoStart and MCT powder to that because those would be easy to travel with I would imagine.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Super easy. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019m not sure how KetoStart tastes in coffee.\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>No. No. Don\u2019t do that. No. They have KetoSpike coffee. So Audacious Nutrition has KetoSpike cocoa, coffee and tea. So in the afternoon I don\u2019t do caffeine after 12:00. So I will brew. I\u2019ll just boil hot water and just put, and the KetoSpike coffee is a good Colombian coffee and it just has the BHB electrolytes in it. So I\u2019ve been doing that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. All right. Cool. I\u2019ll check it out. I\u2019m just trying to figure out, because I went back through all of our conversations, which covers a lot of technical detail as you would imagine. And I\u2019m just wondering what you are most excited about. And right now, I mean, just to volunteer this. I\u2019m very interested in neuroinflammation and the inflammasome, the interplay with the microbiome and how the microbiome can seemingly influence or mediate some of, for instance, the anti-seizure effects of the ketogenic diet. If you get rid of Akkermansia or a few other strains.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Lo and behold, doesn\u2019t really work. And I\u2019m wondering if that applies to other, say, conditions that metabolic psychiatry might be applied for, like schizophrenia and others, I don\u2019t know, but seems interesting as a question. What types of questions or projects or realizations, findings, anything have captured your interest or excitement these days?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. I think just quickly go down the list. Ketone metabolic therapy for cancer, so is one. And we have a pretty comprehensive review that describes the framework for ketone metabolic therapy for glioblastoma, which is a cancer that\u2019s largely resistant to the standard of care. So way much to talk about. It was actually like a 200 plus page paper that was going to be submitted. And we had to basically put a lot of data and things as supplementary figures.<\/p>\n<p>I think there\u2019s like six supplementary figures that tell specifically all the different metabolic drugs that target glucose, glutamine, GKI calculator and a lot of things. So yeah, just Google ketone metabolic therapy framework for glioblastoma and its open access. So that has stimulated research at different places. But I\u2019m excited about research that we\u2019re doing with Moffitt Cancer Center, which is the largest cancer center.<\/p>\n<p>We\u2019re one of the largest in Florida, a tier one cancer center where we\u2019ve got various projects, glioblastoma, maybe a breast cancer, but also lung cancer. So was specifically using ketone metabolic therapy to augment immune therapy, specifically the checkpoint inhibitors. And that has to do with what I described about ketone metabolic therapy, specifically beta hydroxybutyrate activating the adaptive immune system and making checkpoint inhibitors, which is a class of drug that\u2019s, and CAR T therapy.<\/p>\n<p>So now they actually have a study with CAR T therapy and checkpoint inhibitors. So ketones tend to expand the T-cells that are associated with CAR T therapy. So just kind of enhancing that therapy. And with the checkpoint inhibitors, it tends to just enhance cancer specific immunity that is augmented by PD1 inhibitors. So they\u2019re specifically studying that.<\/p>\n<p>So I\u2019m excited about that. So that\u2019s on the cancer front. And then we can jump, if you have no questions, I could jump to other, the Alzheimer\u2019s, the metabolic psychiatry.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Let\u2019s talk, yeah, let\u2019s talk about those. Let\u2019s hop to the Alzheimer\u2019s and metabolic psychiatry. Would love to dive into that because it\u2019s in front of mind for me. And just as a, I\u2019m not sure if I made this clear, doing the couple weeks of strict ketosis, segueing to a sort of 16\/8 ketogenic diet and then moving to kind of a paleo-ish diet has produced some of the best labs I\u2019ve ever had and also the best oral glucose tolerance test that I\u2019ve ever logged.<\/p>\n<p>And from a mood stability standpoint, and I am also for at least the last few weeks, supplementing with the monoester and a diester, the sort of Q-I-T-O-N-E. But all of those things combined, I\u2019ve got to say, psychologically from the standpoint of sustained focus and mood, has been just kind of mind-blowing, to be honest. So I\u2019d love to hear any and all thoughts on Alzheimer\u2019s metabolic psychiatry front.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. So metabolic psychiatry, I would encourage people to listen to Chris Palmer who you, I kind of put on your radar. I don\u2019t know if you remember. I sent you the link to the metabolic \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Yeah. Yeah. Appreciate that.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>So I was like, \u201cYou\u2019ve got to watch this, Tim. It\u2019s going to change sort of the landscape of psychiatry.\u201d\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. I remember that was a recording from a conference, I believe, where he was interviewing one of his patients on stage. Yeah.. I remember that.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>The Metabolic Health Summit, which is part of Metabolic Health Institute, which is you can get educational credits through that. So yeah. We brought Chris in and it was such a compelling story and he treated Matt Baszucki. So Matt Baszucki is the son of Jan and David Baszucki, because he quickly went into durable remission.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Who are well-known from Roblox.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Well-known from Roblox. Yeah. Sort of billionaire philanthropists that are changing, actually, ultimately maybe the standard of care for psychiatry. And I think they single-handedly are funding metabolic psychiatry with Shebani Sethi, she\u2019s at Stanford, Chris Palmer at Harvard, and I work with them closely as an advisor. There\u2019s at least a dozen other institutes that are doing metabolic psychiatry research for schizophrenia, bipolar, major depression, anorexia nervosa, which is a psychiatric disorder that kills more people than any other disorder and a range of different things and anxiety disorders and alcohol use disorders, alcohol withdrawal syndrome. So they\u2019re doing research on that.<\/p>\n<p>So with metabolic psychiatry, there\u2019s a lot of pilot studies, mostly bipolar, looking at a range of different things, ADHD too. And then there\u2019s apps that are emerging like MetPsy, metpsy.com. That\u2019s a collaboration with Dr. Ally Houston, he\u2019s at Oxford and Georgia Ede who might be good to have on the show. She\u2019s from Harvard psychiatrist. So that app is more of a comprehensive app that incorporates ketogenic therapy, but also lifestyle stuff and then coaching. So metabolic therapy coaching for mental health.<\/p>\n<p><strong>Tim Ferriss: <\/strong>How do you spell the name of the app?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>MetPsy is M-E-T-P-S-Y, right? M-E-T-P \u2014 I\u2019m trying to think.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Better at the science than the branding, I guess.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. M-E-T-P-S-Y.com, MetPsy. So I think they have their website up. So they\u2019re basically in their onboarding phase. So they should go live pretty soon. But I\u2019d like to add that the Baszuckis, I remember that they\u2019re funding a big study at Oxford right now and the Baszuckis will match dollar for dollar any donation and spearheading sort of that. Using the app and using ketogenic therapies in combination with lifestyle therapies too.<\/p>\n<p>So metabolic psychiatry is rapidly emerging in a number, and this ties into work we did. I guess my wife did. I was on the paper but she ran the study. We were doing seizure studies with exogenous ketones, and the most efficacious one for this application was the racemic ketone salts in the MCT. We were gavaging them and she was \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>What does gavage mean?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Oh, so it\u2019s basically like tube feeding the animal. So instead of mixing the ketones in with the rat chow, they eat it. And so it\u2019s taking a syringe and based on the weight of the animal, you pull in the amount of ketone ester or this case, it was MCT and ketone salts. We did the esters too, and it did have an anxiolytic effect, anxiety reducing effect.<\/p>\n<p>And then you administer that to the animal and what we are doing is we do seizure studies, put them inside a hyperbaric chamber and we go two to three times more normal and it induces a seizure. But what we observed when we put the animals in ketosis is that instead of them trying to bite us and kill us and not wanting to be held, they were very chill and calm.<\/p>\n<p>So it was just, \u201cWell, this is great. We can handle the animals easier and get them into the chamber without them trying to bite us.\u201d And my wife\u2019s a behavioral neuroscientist and she was like, \u201cWell, we should do some behavioral studies because I think there\u2019s something here.\u201d So we did elevated plus maze. So in this case, the animals can go inside a closed little cave or it can come out into the open arm in the elevated plus maze, which is exploratory behavior. They\u2019re more extroverted if they come out and more introverted and kind of like their fear response if they go into the cave.<\/p>\n<p>So we got results that we published. The title is like \u201cAnxiolytic Effect of Ketone Supplementation.\u201d We published I think three papers and showed the mechanisms and stuff too. So that was an early paper over 10 years ago, just basically showing that inducing acute ketosis with this formulation and doing the elevated plus maze produces an effect that was analogous to a dose of benzodiazepine.<\/p>\n<p>Like if you look at, I don\u2019t know, Xanax or other things in elevated plus maze, it was like, yeah, 20 or 30 percent more time in the open arm. So they\u2019re less fearful to be in environment and making them more like a social lubricant, maybe like Benzo or something. So it had that effect in the animals.<\/p>\n<p>And when we look at the blood work and even take out the hippocampus in the brain, the levels of GABA to glutamate are higher. And then in another study we did with Angelman syndrome, we looked at the mechanism of that and there\u2019s an enzyme called glutamic acid decarboxylase, and a lot of anti-seizure drugs kind of target that.<\/p>\n<p>So the protein levels were higher, essentially showing that your brain converts more glutamate, which is anxiety evoking, like wakefulness enzyme. It\u2019s converting more glutamate, which is excitatory to GABA, which is brain stabilizing. That\u2019s like your chill, like alcohol.<\/p>\n<p><strong>Tim Ferriss: <\/strong>It\u2019s what you take before bed. Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Yeah. So that was, and a variety of different studies, we also looked at adenosine receptor signaling. That\u2019s a little bit more complicated to describe, but there\u2019s a number of different effects contributing to that. So there\u2019s a clear rationale, I think, for depression. If you do an FTG PET scan on someone that\u2019s depressed, it shows glucose type of metabolism.<\/p>\n<p>One thing to mention, I think an important thing to mention in the context of bipolar, you can have a hyper glycolytic effect. And Dr. Iain Campbell from Edinburgh University has published some elegant reviews and is doing some work on that front in describing the research there. But I think it\u2019s important because some of the feedback coming out, and I think you even mentioned too, when ketones get really high, what we observed, if ketones get too high, that can cause an anxiogenic effect.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Get more anxious.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>A sweet spot, maybe one to two. I wouldn\u2019t go above three, probably 1.5 to 2 millimolar range. That seems to be a level of ketones that safely does not produce a metabolic acidosis. So what we do see that when you get above three, it starts to change blood pH.<\/p>\n<p>So it seems to maybe overwhelm the respiratory and renal compensation and your kidneys put out by carb and then there\u2019s respiratory and renal compensation that regulates your blood pH. But the animals that succumb to ketoacidosis and died from the ketone esters that we gave them in early studies had to do with that acidification of the blood.<\/p>\n<p>So it was just an overwhelming, so ketones are acidic and when you deliver it into an ester form, there\u2019s nothing to buffer that. When you give a ketone salt, the electrolytes are kind of like a buffer for that.<\/p>\n<p>So you have the metabolic effect, you have the changing of the brain neuropharmacology, and in bipolar, you throw anti-epileptic drugs at bipolar patients, and it\u2019s largely ineffective. So it makes sense that a ketogenic therapy would work for that.<\/p>\n<p>And the neuroinflammation too. So things that trigger neuroinflammation, and that could be an infectious agent, that could be a virus, that could be T. Gandhi. I mean, it could be like a bacteria. There\u2019s various things that could cause psychiatric disorders. Various infectious agents create that neuroinflammation. So I think neuroinflammation, and then when someone has a seizure too, the inflammatory state of the brain gets much higher.<\/p>\n<p>So I think ketogenic therapies are working through multiple mechanisms, more or less in synergy to produce that. It\u2019s not one mechanism. When we published the NLRP3, I got requests from Genentech and various pharmaceutical companies to go there and give a talk on the mechanism so they could drugify. And I would throw up a big flow chart of all these mechanisms, and I think they would get frustrated. And it was like, \u201cWell, tell us the mechanism so we can make a drug out of this.\u201d<\/p>\n<p>But I think the beauty of ketogenic therapies is that it\u2019s pleiotropic, right? Which means it\u2019s many mechanisms working in synergy. You could say Metformin, GLP1 drugs are working through metabolism, and they\u2019re kind of pleiotropic also.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Do you use either of those?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I\u2019ve experimented with metformin, and that is a way for some patients to increase their ketone levels. So we\u2019ve published on metformin from the context of that it increases mitochondrial oxidative stress, so it\u2019s a weak toxin to deliver. Most people didn\u2019t know that when we were studying that. And I think metformin can enhance, increase AMP kinase, maybe increase insulin sensitivity and has a very weak effect at reducing blood glucose if you have a normal glucose. But it does tend to increase ketones a little bit.<\/p>\n<p>And I think there\u2019s about 150 studies on clinicaltrials.gov right now on metformin, as a means to augment cancer therapy. So I think that could be a tool in the toolbox for some people. When I take it, and I do really intense \u2014 if I do an intense workout, I felt sick. An issue with metformin is it could produce lactic acidosis. It\u2019s producing lactic acidosis because it\u2019s a weak \u2014 it is a toxin to the liver, so it\u2019s de-energizing the liver. But also when I took it up to two grams per day, I had a photosensitivity. So when I went outside, the sun gave me a rash.<\/p>\n<p><strong>Tim Ferriss: <\/strong>You mentioned on your wrists.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Am I making that up? Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, it tended to correlate with that. And then I got off of it. Then I experimented with it again and it tended to be \u2014 at the begin \u2014 I\u2019m in Florida and it was May. It\u2019s like when the sun\u2019s really starting to crank. Then I just go outside all day and it\u2019s like, \u201cWhere is this rash coming from?\u201d So it\u2019s a photosensitivity reaction that I got and that concerns me. So I have it, but I don\u2019t use it.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>May I ask you a quick question just related to metformin for a second?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Mm-hmm.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Is I was looking back on notes on prior conversations, and I think you mentioned Dale Bredesen on an episode of STEM-Talk. But specifically, for folks with the APOE4 genotype, like yours truly, do you think metformin may be more interesting? But let\u2019s assume in my case, let\u2019s call me metabolically healthy. So maybe yes, maybe no. I remember a long time ago having a chat with Nav Chandel, I want to say, I might be getting the name slightly wrong, from Northwestern. He was like, \u201cAh, if you\u2019re doing a bunch of exercise and getting your diet straight,\u201d he\u2019s like, :I don\u2019t think that you\u2019re going to see a lot of benefit.\u201d But he didn\u2019t have the APOE4 information on me. And then berberine I have written down for some reason. I\u2019m just wondering if there\u2019s anything to either of those for APOE4 specifically?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, berberine is pretty similar to metformin\u2019s glucose lowering effect. So that\u2019s something that you can consider if you don\u2019t want to take metformin. I\u2019m of the opinion that for the general population, eating a standard American diet that is averse to working out and just trying to really modify their diet, metformin I think is a very potentially effective drug for longevity. It\u2019s going to reduce blood glucose, since most people are pre-diabetic, or have type 2 diabetes that are in their 40s, 50s, and 60s. And it will reduce your incidence of cancer, specific kinds of cancers like pancreatic cancer. I think the data\u2019s good on that, and I think it\u2019ll shift metabolic biomarkers that we have historically good data on in the right direction.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Does metformin do anything that taking a GLP-1 like tirzepatide or something doesn\u2019t do? I\u2019m just wondering if it\u2019s an additive effect.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Well, they\u2019re totally different drugs. But people who take metformin and one gram to two gram dose, two grams is high. But when they do that, they tend to eat less calories. So it does create \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>I see.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>A little bit of, for me, GI issues. Maybe a little bit of loose stools in the beginning, and that could be factoring in there. So it does tend to improve metabolic biomarkers across the board if you\u2019re trending towards metabolic dysregulation or metabolic syndrome. A GLP-1 works essentially through caloric restriction and just increasing appetite through in part, a mild gastroparesis and decreasing gastric emptying time. But also works on the brain, and I think has a wide range of beneficial effects. I think it\u2019s a game-changing drug that\u2019s going to change the whole landscape of metabolic therapies. And I think \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, seems to have a \u2014 from what I\u2019ve read, and maybe I don\u2019t want to over interpret here, but potential neuroprotective effects, right?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So that\u2019s the main reason I would be looking at potentially low-dose GLP-1.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I like the low dose. I like that you preface it with low-dose because I think higher doses are not studied enough long-term to avert potential side effects that we don\u2019t know about.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. And do you take berberine or is it superfluous because of the diet, you don\u2019t really need anything to lower glucose?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I\u2019ve experimented with it and it did decrease my glucose in response to a meal. I did dihydroberberine, which is a more potent version of berberine. But interestingly, after about a week, I started to get a headache. And then I got off \u2014 I don\u2019t know if it has a vasodilate or maybe it impacts liver metabolism in a way that was \u2014 who knows? Maybe decreasing my caffeine metabolism. These are things that come to mind. I am a fast metabolizer of caffeine.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, you still consume quite a bit of coffee. Yeah?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I do. I fill this up. So this is Metabolic Mind. Actually, Metabolic Mind is part of the Baszucki\u2019s Group metabolic psychiatry. So I have \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. So you\u2019re holding up \u2014\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I do one of these per day. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What is that? That\u2019s like 16 to 20 ounces, something?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>24. I think about 24 ounces.<\/p>\n<p><strong>Tim Ferriss: <\/strong>24 ounces.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Okay. It\u2019s metal. It looks like a thermos, basically.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Okay, got it.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Relatively strong coffee. I do that and pour one cup, and I usually finish it about now and no caffeine. Yeah, caffeine at four or 5:00 p.m. is probably going to disrupt sleep latency and sleep timing. But yeah, GLP-1, amazing class of drug. We\u2019re covering that now at med school in our nutrition courses we\u2019re teaching.\u00a0<\/p>\n<p>And then the SGLT-2 inhibitors are also a pretty interesting class of drug that I think has a lot of potential. So if someone trying to bring their glucose levels down, for example, trying to get that \u2014 these are prescription drugs. So of course, go to your doctor. But that\u2019s a pretty good lever to pull, especially if someone\u2019s resistant to dropping their carbs, if they\u2019re eating some carbs.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, GLP-1 and SGLT-2 are great.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, this is also a tool in the toolkit with, let\u2019s just say elderly patients who are \u2014 even if they wanted to comply, may not have the mental faculty to comply with ongoing. And you can\u2019t have, necessarily, 24\/7 supervision to prevent them from eating bagels. Which maybe you can do. Just all the meds in the morning and then one injection a week or whatever it might be. Do you take any supplements or medications with the explicit goal of mitochondrial health or maybe just the side effect of mitochondrial health?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Well, I think ketones shine there. The D, both the D and the L, beta-hydroxybutyrate. So that\u2019s first and foremost. And we are doing research with NAD.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>These injectables?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>I can\u2019t talk about the research that we\u2019re doing in depth. But we\u2019re working with Metro International Biotech. So they have phase two and phase three trials for Alzheimer\u2019s. So there\u2019s NR, nicotinamide riboside, nicotinamide mononucleotide. So the problem with those is that the liver is pretty greedy and takes a lot of that. And then the muscles are \u2014 so a lot of it\u2019s maybe not getting to the brain.<\/p>\n<p>But if people just Google MIB-626, so that\u2019s one of their drug forms of NAD, that\u2019s a stabilized form of NAD. And then they have a whole suite of NAD molecules that most people don\u2019t know about, but are in experimental trials. And we\u2019re doing some of those preclinical animal model work in our labs. So I do think \u2014 for certain applications, we didn\u2019t see an effect. But at the same time, they are \u2014 for applications like non-alcoholic fatty liver disease, maybe Alzheimer\u2019s, maybe inflammatory disorders, improving. If used for a long period of time, markers of mitochondrial health I think improve. So NAD, people may know NAD is basically a substrate for the sirtuins and various enzymes. There\u2019s 500 different enzymes. So a class of proteins that are called sirtuins rely heavily on NAD. So this is an important thing to consider.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>And this sirtuin is just for folks who are like, \u201cHave I heard that before?\u201d I want to say back in the day when resveratrol was everywhere in the news and super mouse and all you have to do is drink wine, but maybe 20 cases of wine. All of that stuff with trans-resveratrol, that\u2019s where the sirtuins popped up?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>The sirtuins are really heavily reliant on NAD. And NAD is involved in everything that we study. So five to 600 metabolic enzymes need NAD for fuel. So that\u2019s important to consider. And DNA repair is exclusively tied to NAD levels. So remember I mentioned reductive stress with D-beta-hydroxybutyrate?<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Reductive stress means that the NAD to NADH ratio would drop. So you get more NADH relative to NAD. That could be problematic because the availability for NAD may not be there for sirtuins and other \u2014 so a redox balance formulation.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I see.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>So that feeds back. I don\u2019t want to get too far into that, but I think it\u2019s impacting the redox balance, which is getting us to revisit the various ketogenic formulations and to study this, in cell-based systems, animal models. It\u2019s hard to do in humans. You could do a 31-phosphorus MRS if you have a four or 7-Tesla system like Harvard has. So this is one way to look at like phosphocreatine, ATP, pH, and also NAD to NADH ratios. So this is one way. Actually, we do have that at our Alzheimer\u2019s center, and that\u2019s on the list of to-dos, to look at this reductive kind of stress thing.<\/p>\n<p>So NAD, I\u2019m just throwing that out there. I think there\u2019s a lot of criticism towards NAD now. That happens from time to time. Because moving science from cell-based systems to animal models to humans, there\u2019s a massive learning curve there. We\u2019re learning that with some of the ketogenic agents. We\u2019re just at the cusp of really understanding the dosage, timing, scheduling and form of exogenous ketones that\u2019s optimal. And it\u2019s going to vary dependent upon the situation that you\u2019re trying to treat. And also individually, I think people are going to have. So that opens up this whole personalized precision ketogenic metabolic therapy, or the NIH is throwing a lot of money on personalized medicine based on genetic markers, and based on biomarkers that some of them that you can measure in real time. Like continuous ketone monitoring, continuous glucose, and maybe lactate monitoring.<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s cool. Yeah, that\u2019s very cool. One last supplement question because I\u2019m looking back at past notes. And I\u2019m probably going to mispronounce this. But idebenone, more observable version of CoQ10. Maybe that\u2019s a fair description. Maybe it isn\u2019t. Do you still take that or no longer?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I think CoQ10 is on the short list of five supplements that I would recommend to people. Although I don\u2019t take it, I do get quite a bit from the foods that I eat. I eat a lot of heart, liver, animal products that have CoQ10 in it. But if you\u2019re on a statin, if you\u2019re on metformin and other drugs, they could potentially deplete you. And then CoQ10 has a solid track record for cardiovascular health. So idebenone is a drug stabilized form of that. And then when I discussed that on your podcast, that was in the context of something called the Deanna Protocol. The Deanna Protocol is after Deanna Tedone. She has ALS, she was diagnosed well over a decade ago, was given two or three years to live. She\u2019s alive and well today, we\u2019re just emailing me yesterday. So Deanna Tedone had advanced ALS and then has been stabilized using the Deanna Protocol, which is included at the time, idebenone. But I think it became a drug.<\/p>\n<p>So idebenone became the standard of care for Friedrich\u2019s ataxia, and then you couldn\u2019t get it on Amazon. But I think ubiquinol, or CoQ10, it would be a good substitute for that. And I don\u2019t use it myself. But I think that\u2019s if you\u2019re older in age and you have cardiovascular heart problems in your family. However, with that said, we actually ubiquinol, we did high doses in our animal models, and we saw some kidney toxicity. We had some animals die. And \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Oh, Jesus. It\u2019s like \u2014\u00a0<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>But that was rodent models we used. Again, we use really high dose for oxygen toxicity. We\u2019ve looked at everything under the sun. But it was this unexpected side effect. Then I went to the literature and showed that it\u2019s such a powerful antioxidant in some ways, and it maybe was concentrating in the kidneys. So there was a couple of papers came up, and then we think that that\u2019s why the animals may have died. We were using a MitoQ, like various forms that are more mitochondrial specific. We\u2019re using more potent forms of the CoQ10. So it may not be similar to the commercially available forms.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What are the other supplements on that short list? You said four or five supplements. What are the other ones?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>That I take. Yeah, so creatine monohydrate would be the staple thing that I\u2019ve used since I was a teenager. First and foremost, exogenous ketones, and the data is emerging on that, I think that\u2019s going to be the next creatine for that. But creatine, for Alzheimer\u2019s disease, we didn\u2019t talk about it. But a dosage of 10 to, even if you\u2019re larger, 20 grams. And that\u2019s not a misspeak there, 20 grams of creatine. Spread out maybe five grams, three to four times a day for advanced Alzheimer\u2019s, if you can tolerate it. [inaudible 02:20:12]\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019m taking 20 grams today just because I didn\u2019t get very good sleep last night. I just find it to help with recovering from, let\u2019s call it sleep deprivation. But yeah, got to watch the split dosing.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah. Vitamin D, but you have to measure that in your lab. So you want that to be \u2014 you don\u2019t want it over a hundred, right? So you want vitamin D levels that are probably like 60 to 80, would be a good level of vitamin D and getting that checked. But I think you should check it first. It\u2019s weird. I live in Florida, I get tons of sun. But if I\u2019m not supplementing vitamin D, I trend to be low 30s. It could be trend \u2014 but so when I supplement it, I basically stay in the mid-60s to 70s. So vitamin D and melatonin, I think is a great neuroprotective antioxidant supplement to take at nighttime. And I don\u2019t take omega-3 supplements, but just because I did \u2014 Rhonda Patrick connected me with the omega-3 guy and I tried the OmegaQuant. My DHA levels and EPA levels were off the charts.<\/p>\n<p>Out of curiosity, I got off of fish for a month or so and it went down to normal ranges. And then I tried Nordic Naturals, which \u2014 it was a company that reached out to me and I was like, \u201cOkay, well, I\u2019ll remove omega-3s from my diet and then add it back in with a dose.\u201d And it popped me back up to a level similar to if I\u2019m eating tons of sardines per day. So if you don\u2019t like sardines and you don\u2019t like eating a lot of fish, I think Nordic Naturals is probably one of the go-to brands. I\u2019m not paid to say that or anything, but they\u2019re legit. But you could do the OmegaQuant test. I think there\u2019s so much data on EPA and DHA that I think ultimately, the omega-3 levels will be part of standard blood work. There\u2019s so much data emerging on that, that I think probably within the next 10 years, when you get comprehensive metabolic panel, CBC, DHA, and EPA will probably be added to that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right, Dom. Well, we could go for many more hours, I am sure. But let\u2019s start to land the plane for this round. And I do want to ask, of course, if there\u2019s anything else that you\u2019d like to mention or point people to. Anything you\u2019d like to recommend, formal complaints you\u2019d like to lodge? People you\u2019d like to secure in front of a large audience? No, I\u2019m kidding. But anything that you\u2019d like to say or point people to? Any resources, anything that you\u2019re up to, where they can find you? Anything at all?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I just want to mention KetoNutrition. That\u2019s our informational website, ketonutrition.org. And we\u2019ve hosted a conference where many people, Dr. Valter Longo, Rhonda Patrick, who\u2019s been the keynote speakers, that\u2019s the Metabolic Health Summit. That\u2019s been the conference, and that is run by Metabolic Health Initiative. So I direct people to Metabolic Health Initiative, and it\u2019s run by three of us. My colleagues, Dr. Angela Poff and Victoria Field run that show. I tag on for the ride.<\/p>\n<p>But that\u2019s an ACCME, accredited medical education platform. So everything that we\u2019re talking about here, we have speakers and we create a medical education platform, so people can learn about metabolic psychiatry. People can learn about metabolic based therapies and metabolic drugs, like GLP-1 drugs and hormone optimization and things like that. So I would mention that. The brand of ketones that I use that I often get asked is Audacious Nutrition KetoStart. So that evolved out of our work with cancer, neurodegeneration and seizures. We\u2019re doing work at Byrd Alzheimer Center on probably 20 or more ketogenic compounds in development that are mostly alcohol-free. So I think all of them are actually. We have some really interesting studies on Alzheimer\u2019s and a lot of other \u2014 so hopefully in the next year be able to share some of that preclinical animal model work. Hyperbaric oxygen, so we have a 28 million study \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s huge.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>At the University of South Florida. I am just peripherally involved in that or just know the people running that. And it\u2019s essentially evolved out of the DOD work that looked at the muddy waters of hyperbaric oxygen therapy for that. But I \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>It\u2019s a good way to put it. The muddy waters.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, I\u2019ve been part of reviewing grants and also manuscripts, and I think there\u2019s a lot of interesting studies that\u2019s going to emerge. By the time this airs, I think they will be on PubMed. Essentially, showing that hyperbaric oxygen therapy protocols, more mild hyperbaric oxygen at 40 to 60 sessions, and people that had traumatic brain injury a decade ago, can enhance cognitive function, reaction time, and a wide variety of metrics associated with brain function. So I think this work coming out of Israel, I would like to see it replicated. I would like to see \u2014 the work that\u2019s different at the University of South Florida is that it\u2019s very innovative and that it\u2019s using a sham.<\/p>\n<p>Instead of using hyperbaric air as the control, they\u2019re using \u2014 they basically pulse pressure in the beginning to make people think they\u2019re being pressurized and at the end, so their ears pop a little bit. And I don\u2019t know every \u2014 it\u2019s blinded. People don\u2019t know even what they\u2019re getting. If you question them, they don\u2019t know if they\u2019re getting hyperbaric oxygen. But I do think that oxygen is a powerful drug, and I am excited about that research, if you ask me. I\u2019m excited if it proves it or disproves it. I think we\u2019re going to get an unambiguous answer to this question about hyperbaric oxygen for a traumatic brain injury, and people with and without post-traumatic stress syndrome. So my thing is that if they put patients on ketone metabolic therapy, that would augment and enhance hyperbaric oxygen therapy, and decrease the potential for risk of an oxygen toxicity seizure, which goes up. If you\u2019ve had a traumatic brain injury, your risk of oxygen toxicity seizure would increase because \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Now, this is pretty specific to military? Or what are we talking about?<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah, they\u2019re all vets. And if they do find out that they get a beneficial effect from that, then after the experiment, they\u2019ll be able to get that for free service. So there\u2019s six \u2014 like quarter to half a million dollar hyperbaric chambers. So the hard shell chambers, there\u2019s six of them in this facility. And it\u2019s the most elaborate hyperbaric oxygen therapy study that has ever been done. And it\u2019ll answer the question about the efficacy. So that\u2019s ongoing now, and I\u2019m excited about that. I\u2019m also excited about potentially using that facility, because it\u2019s next to the Moffitt Cancer Center for patients that are undergoing various cancer treatments that could be enhanced with hyperbaric oxygen therapy. Because it augments the immune system and it\u2019s actually an FDA approved application for radiation necrosis. So if you\u2019ve had radiation, then your insurance would actually cover it. But it can enhance certain therapies that we\u2019re working on now. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Amazing.<\/p>\n<p><strong>Dr. Dominic D\u2019Agostino: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. Well, we will link to all of those things in the show notes as always.
