“The biggest secret is saying no to 99 percent of the things that many people consider ‘normal’ so what you care [about] gets done.”
— Sami Inkinen
“The human experience is 100 percent subjective and if you’re not in touch outside of that, it’s just computers and algorithms. And when you really tune into the subjective experience, oftentimes the biggest decisions in life are based on that.”

“The love language of American capitalism is dollars. And so when you can help someone else to make money, you’re going to be very, very successful.”

Want to hear another conversation about ketones, metabolic health, and what your devices might be missing? Listen to my conversation with ketogenic-diet researcher Dr. Dominic D’Agostino, in which we discussed the ketone measurement paradox of feeling sharp at low readings, the carburetor analogy for ketone production versus utilization, metabolic memory and becoming more fat-adapted over time, my 18-day keto experiment, intermittent fasting as a keto on-ramp, the glucose-ketone index sweet spot, post-meal walking and GLUT4 activation, one-week-per-month protocols, low-carb Mediterranean as the 80/20 minimum effective dose, and much more.
