Lean Body Mass

Lean body mass is everything in the body that is not fat: muscle, bone, water, and organs. It comes up when discussing why many people prioritize protein — the general goal of preserving muscle while eating less — and it is measured by methods (DEXA, bioimpedance) with varying accuracy. We use the term to give context to nutrition goals, factually. Nothing here claims a specific effect of any product on your lean mass; that is an individual outcome shaped by far more than a supplement.
