The cyclic metabolic switching theory of intermittent fasting - Nature Metabolism
In this Perspective, Mattson discusses that the beneficial effects of intermittent fasting (IF) are mediated by cyclic metabolic switching between ketogenic (fasting) and non-ketogenic (fed) states and that this explains the added health benefits of IF over caloric restriction and ketogenic diets.
