What Five Days of Fasting Can Do to How You Age — The Science Behind the Revolution

Most people think of fasting as a weight loss tool. Dr. Valter Longo's research reframes it entirely — as one of the most powerful interventions available for how you age at the cellular level. Barry Alexander Brown is the filmmaker who spent years bringing that science to life, shooting from California to Ecuador and across Italy to document the Longevity Revolution in a documentary narrated by Edward Norton. What he shares about the plant-forward daily habits and fasting practices that the longest-lived populations on earth actually follow, the science foundations behind the film that make the five-day fasting protocol so compelling, and what the cultural shift toward healthspan over lifespan means for how you think about the decades ahead will give you the most accessible and visually grounded introduction to longevity science you have encountered. You do not have to move to Sardinia to live like you are from there. This episode shows you where to start. You’ll learn (fast): How fasting + mostly plant-based eating can support healthspan The science foundations behind the film (and where to dig deeper) Barry’s creative process from editing icons to directing docs to writing novels Barry is also speaking on a panel about the film at the Nutrition & Longevity Festival (Cervia, Italy — Sept 14, 2025).
