Frequently asked questions
What is lean body mass?
Lean body mass is all of the body's non-fat tissue, including muscle, bone, organs, water and skin, as opposed to stored body fat.

No; muscle is part of lean body mass, but LBM also includes bone, organs and body water, so it's a broader measure than muscle alone.

Eating enough protein, training with resistance and dieting in a moderate rather than extreme deficit all help preserve lean body mass during fat loss.
