Step into the world’s leading longevity lab as Dan Buettner sits down with Dr. Valter Longo, the pioneering Director of the Longevity Institute at USC, to uncover the "best medicine" already hidden within the human body. This episode breaks down the radical science of the Fasting Mimicking Diet, a revolutionary approach that tricks your cells into a state of deep repair—shrinking and regenerating vital organs like the heart and pancreas without the extreme struggle of water-only fasting.

Discover how these ancient biological programs can actually reverse your biological age by up to two and a half years in just three months, while protecting your muscle mass far more effectively than modern weight-loss drugs. Dr. Longo challenges popular health myths, explaining why your "healthy" protein intake might be shortening your life and how even a daily apple could be contributing to hidden weight gain. From the secrets of Italian centenarians to cutting-edge clinical trials, this conversation provides a definitive roadmap for harnessing your body's natural ability to heal, rejuvenate, and fight disease from the inside out.
