Nutritional Biochemistry

I often get asked, ‘Which diet works best?’. In my view, this is simply the wrong question. Nutritional biochemistry is a powerful lever in our longevity toolkit, but it is much more than fad diets or the number on the bathroom scale. A better question might be, “how can I use nutrition to support my metabolic health?”

Reframing the goal toward metabolic health is a critical starting point. From there, you can combine general principles of nutrition science (such as how much protein you need) with personalization tactics (such as using a CGM to monitor glucose levels) to build a nutrition plan that makes sense for you.

See the collection of audio clips, podcasts, and articles below to learn more about my nutrition and fasting framework.

#194 – How fructose drives metabolic disease | Rick Johnson, M.D.

“Fructose turns out to have been meant to be this wonderful system for survival, but in our culture with the amount of sugar in foods that we are eating (that either provide sugar or can be turned into fructose), this pathway has become hazardous.” —Rick Johnson

#193 – AMA #31: Heart rate variability (HRV), alcohol, sleep, and more

In this “Ask Me Anything” (AMA) episode, Peter and Bob first answer a variety of questions related to heart rate…

Is alternate-day fasting superior to calorie restriction for fat loss in lean adults?

A recent study suggests ADF is no magic bullet

#167 – Gary Taubes: Bad science and challenging the conventional wisdom of obesity

“Doing a background analysis is the hard, relentless, rigorous grunt work of science. It’s endless and thankless, because if you do it right, all you’ll do is prove that you were wrong all along.” —Gary Taubes

Are continuous glucose monitors a waste of time for people without diabetes?

Some experts suggest CGMs are useless for nondiabetics. I disagree.

#165 – AMA #24: Deep dive into blood glucose: why it matters, important metrics to track, and superior insights from a CGM

“Hyperinsulinemia on an [oral glucose tolerance test], even in the presence of normoglycemia, is the canary in the coal mine.” —Peter Attia

#163 – Layne Norton, Ph.D.: Building muscle, losing fat, and the importance of resistance training

“I always tell people, I don’t think I would’ve had the success I did in business or social media or academia if I hadn’t done weightlifting because that taught me so much about other things in life.” —Layne Norton
