Can aging be stopped before it starts? Dr. Nir Barzilai reveals the science-backed longevity protocol to prevent age-related diseases and reverse your biological clock. Dr. Mark Hyman is joined by Dr. Nir Barzilai, a leading geroscientist and the founder of the Einstein Nathan Shock Center. Together, they break down the critical difference between chronological age and the actual biology of aging, revealing how we can target aging at its root source to dramatically extend our clinical health span. Dr. Barzilai shares his personal longevity routine—including intermittent fasting, strict daily exercise, and sleep habits—while diving deep into his groundbreaking research on "SuperAgers." Discover why certain genetic traits, like surprisingly low IGF-1 (growth hormone) levels, protect centenarians from chronic disease, and how everyday people can mimic these effects. We also explore the controversial truth about metformin, the highly anticipated TAME trial, and why simply chasing the newest peptides or taking 100-supplement stacks might be doing more harm than good. If you want to understand the future of evidence-based longevity medicine without the biohacking hype, this conversation is for you. #Longevity #AntiAging #Metformin #DrMarkHyman #SuperAgers Get my FREE guide 3 Steps to Reverse Aging when you sign up for my weekly health picks 👉 https://bit.ly/IncreaseHealthspan View the Show Notes For This Episode: https://bit.ly/ep-852 This episode is brought to you by Sunlighten, Cozy Earth, BiOptimizers, and Fatty 15.
