Hi there Lifespan Community, Hope you had a Merry Christmas and New Years, today we are looking into the importance of nutrition and the impacts it has on our longevity.

Dr. Matt Kaeberlein is a globally recognized expert on the biology of aging and recurring on The Drive. In this episode, Matt explains his research findings on nutrition as it relates to aging and longevity, including the results from his recent review article in Science. From there, he and Peter dive deep into the literature on calorie restriction (CR), explaining the nuance, benefits for lifespan and healthspan, and potential downsides of CR. He discusses the epigenetic changes that occur with age and potential benefits and downsides of epigenetic reprogramming, often viewed as a panacea for reversing aging. Matt also explains the impact of dietary protein on aging, including the interesting dichotomy around how protein, a critical macronutrient, and rapamycin, a geroprotective molecule, have opposite effects on mTOR. Additionally, he talks about low-protein vs. high-protein diets and their effects on muscle mass and mortality, as well as the impact of IGF-1 signaling and growth hormone on lifespan.

This is a great podcast and its worth a listen.

Thanks for taking the time to watch this podcast.
