Should you eat less food, or eat less often? Harvard geneticist Dr. David Sinclair argues the gap between meals may matter more than most people think.

In this commentary edition of Wellness Blueprint, we take the key moments from Sinclair's conversation on when to eat and what to eat for longevity, and add our own commentary between the clips to explain the science in plain English.

What you'll learn:

Why Sinclair separates "eating less" from "eating less often"
What sirtuins, NAD, mTOR, AMPK and autophagy are, and why they come up in aging research
The 16:8 time-restricted eating approach and how Sinclair describes his own routine
Why fasting is not starvation
How sugar, protein, red meat and amino acids connect to nutrient-sensing pathways
What plant-based, Mediterranean and Okinawan diets have in common
Xenohormesis: how plant stress compounds may affect us
Sinclair's final idea, the "state of want"
