Could fasting extend your lifespan? | Dr. Valter Longo and Prof. Tim Spector

This interview podcast explores the concept of biological age versus chronological age and how to slow down aging. The hosts discuss various methods, including fasting, with Dr. Valter Longo, a leading researcher in longevity, and Prof. Tim Spector, a nutrition science expert. Dr. Longo highlights the impact of fasting on gene expression and introduces the "fasting-mimicking diet," a five-day program shown to reduce biological age by 2.5 years in some studies. Prof. Spector emphasizes the importance of a holistic approach, combining fasting with a diet low in ultra-processed foods. Listeners gain insights into different fasting methods and their potential effects on health and longevity, along with the understanding that individual responses vary.
