The Biology of Slowing & Reversing Aging | Dr. David Sinclair

In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don't Have To, and the host of the Lifespan Podcast, which launches January 5, 2022.  In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology. This episode includes lots of basic science and specific, actionable protocols, right down to the details of what to do and when. By the end, you will have in-depth knowledge of the biology of aging and how to offset it. Read the full show notes for this episode at hubermanlab.com.
