In this episode, Dr. David Sinclair and co-host Matthew LaPlante discuss how frequently we should eat, what food we should avoid, and what food we should pursue. They discuss the science behind how a "low energy state," which can be induced by a period of fasting, combats aging and promotes health. They also walk through research that points to the benefits of a mostly plant-based diet for slowing aging and offer key insights into when to eat and what to eat to maximize longevity.
