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.
