In this episode of MASS Office Hours Live, hosts Dr. Eric Trexler and Dr. Eric Helms discuss a variety of fitness and nutrition topics, with a main focus on the concept of metabolic adaptation. They explore whether metabolic adaptation is a myth or an illusion, explaining that most of the adaptive decrease in total daily energy expenditure (TDEE) comes from reduced non-exercise activity thermogenesis (NEAT) rather than resting metabolic rate (RMR). The hosts also answer various listener questions, providing advice on protein intake, bench press technique, strategies for satiety while dieting, hamstring training, managing fatigue during a cut, aerobic training for health vs. performance, the potential use of nicotine as an appetite suppressant, and much more.
