    63. Does Autophagy Actually Prevent Cancer and Slow Aging?

    02/15/2026 | 47 mins.
    In this episode, Sam is inspired by her family's interest in fasting for autophagic response to do some research. Autophagy is sold to us as a cancer-killing agent—according to some Healthtokkers, a single autophagy-boosting caloric fast can halve your risk of developing cancer. Is that true? Are there limitations or variables? And how does it affect your pace of aging? All questions this episode will address.
