He wants to sell you a $300 ‘fasting diet’ to prolong your life. It might not be as crazy as it sounds. (STAT)

STAT published a profile on Valter Longo of the USC Davis School and his research on the benefits of fasting and fasting-mimicking diets, and how the body ages. Fasting “is at the foundation of the body’s ability to protect, repair, and rejuvenate itself. We started to wonder: What can we use it for?” Longo said. Longo spoke about how his initial research on aging met some pushback from the scientific community. STAT also published a review of Longo’s fasting-mimicking diet.
