Jason Fung's video: The Physiology of Intermittent Fasting Science Jason Fung

Dr. Jason Fung provides a detailed description of the physiology of fasting, what happens to our body as we stop eating. Knowing this may help you lose weight. The body transitions by first using glucose from the food. In the second stage, it breaks down glycogen into glucose. In the third stage, it uses protein to make glucose, a phase called gluconeogenesis. After that, the body sustains itself mainly on stored fat.
