How Intermittent Fasting and Hormetic Stress Boost Brain Health and Longevity
Dr. Mark Mattson, one of the world's most cited neuroscientists, explains how mild stressors like intermittent fasting and exercise trigger beneficial adaptations that protect against aging and neurodegeneration. The episode explores metabolic switching, where the body alternates between glucose and ketone fuel sources during fasting periods. This process enhances brain function, promotes cellular repair, and may prevent Alzheimer's and Parkinson's disease. Mattson discusses different fasting approaches, including time-restricted eating versus 5:2 protocols, and how combining fasting with exercise creates additive benefits. He also covers plant compounds that mimic fasting effects, age and gender considerations for fasting protocols, and the difference between beneficial acute stress and harmful chronic stress.
