Aging, mTOR, Sirtuins, Rapamycin, Metformin, the Truth of Resveratrol & Longevity Supplements, David Sinclair & Anti-Aging Myths | Matt Kaeberlein | 151 | Mind & Matter

The podcast explores the science of aging, examining factors influencing longevity across species and within individuals. Matt Kaeberlein, CEO of OptiSpan, discusses the evolutionary perspective on aging, highlighting the roles of body size, metabolic rate, and reproductive viability. He notes the mysteries surrounding longevity mechanisms in outlier species like naked mole rats, and the impact of growth pathways like mTOR and IGF-1 on lifespan. Kaeberlein cautions against oversimplified interpretations of caloric restriction and advocates for a proactive, preventative approach to healthcare, emphasizing the need for a paradigm shift towards prioritizing healthspan. He also addresses common misconceptions around supplements like resveratrol and NMN, and advocates for routine testing of vitamin D, B12, Omega-3, and hormone levels.
