Caloric restriction vs. periodic fasting and the importance of re-feeding after a fast

Parent Episode: Valter Longo, Ph.D. on the Fasting-Mimicking Diet & Fasting for Longevity, Cancer & Multiple Sclerosis

Caloric restriction is a sustained reduced intake of approximately 30 percent fewer calories than one would typically eat, whereas periodic fasting is a more extreme deficit, but only for a short duration. Periodic fasting has distinct phases, unlike caloric restriction: during the acute deficit stage stem cells are activated, and during the refeeding stage, our systems are allowed to regenerate. In this clip, Dr. Valter Longo explains the difference between caloric restriction and periodic fasting and highlights the importance of refeeding after a fast.
