#157 - AMA #22: Losing fat and gaining fat: the lessons of fat flux

In this “Ask Me Anything” (AMA) episode, Peter and Bob take a deep dive into fat flux. They define the major players that impact the flow of fat entering and exiting a fat cell, which determines how much fat a person carries. They discuss the significant influence that insulin has on the net fat balance and explore common strategies, such as fasting and low-carb diets, that have efficacy in the liberation and oxidation of fat from fat cells. Additionally, Bob explains his research process and how he seeks answers to Peter’s challenging questions.
