Your body already knows how to live to 120 in perfect health. It's just not doing it. That realization is what sent Dr. Chris Rhodes down the fasting research path during his PhD in nutritional biochemistry at UC Davis.

His argument? Most people doing 16:8 intermittent fasting aren't getting nearly the benefits they think they are. The body doesn't flip into fasting mode until glycogen stores are depleted, which typically takes 20 to 24 hours. Autophagy, stem cell regeneration, and the real anti-inflammatory benefits don't peak until around 72 hours.

In this episode, Dr. Rhodes, creator of Mimio – the world's first fasting mimetic supplement – explains what his team discovered when they tracked metabolites during 36-hour fasts in healthy subjects, as well as how they isolated four synergistic molecules that recreate fasting benefits at the cellular level.

We also dig into something personal. Almost a year ago, I started supplementing with Mimio and tracked my biological age using TrueAge epigenetic testing before, during, and after.

The result? My pace of aging slowed to 0.85 – meaning that for every calendar year, I'm only aging about 10 months biologically.

Rhodes walks me through what the epigenetic markers actually mean, why some of my results seem contradictory on the surface, and why the phenotype matters more than the genotype when it comes to practical health decisions. 

We also get into why fasting can disrupt hormonal cycles through caloric restriction signaling, why elite athletes rarely have exceptional longevity despite peak fitness, and why combining actual fasting with Mimio may produce better results than either one alone.

About Chris Rhodes:

Dr. Chris Rhodes, PhD, spent 8 years researching fasting at UC Davis before discovering that specific molecules produced during a fast can reduce inflammation, fight oxidative stress, and support metabolic health. That research led him to create Mimio, the world's first fasting mimetic supplement, backed by three clinical studies and designed to deliver measurable longevity benefits without changing your diet or lifestyle.
