In this episode, we journey through millennia to uncover the incredible story of fasting. We explore its origins in the "feast or famine" cycles of our earliest ancestors, its sacred role in global faiths from Christianity and Islam to Hinduism and Buddhism, and the cutting-edge science that is finally explaining why it works. Discover the Nobel Prize-winning process of "autophagy"—your body's own cellular cleaning crew—and learn how this ancient discipline can reset your metabolism, sharpen your mind, and potentially extend your healthspan.
