About this episode

Bodybuilders are laser-focused on retaining as much muscle as possible while dieting, and for very good reason. In that context, the smallest details matter. But what about everybody else? This episode explores a hot take on weight loss, lean mass loss, and why the usual fear of losing muscle may be overstated in the context of successful long-term weight loss. Drs Eric Helms and Eric Trexler break down what lean mass loss actually represents, how body composition changes in obesity differ from bodybuilding or weight cycling, and why the health benefits of sustained fat loss substantially outweigh moderate losses in fat-free mass.
