lean body mass

Non-fat body tissue

Lean body mass is the weight of everything in the body except fat—muscle, bone, organs, water, and connective tissue.

It's a key metric in fitness and medicine for assessing physical composition: Her lean body mass increased even though her weight stayed the same.

Distinguished from fat-free mass, which excludes essential fats.
