About Lean Body Mass
What is Lean Body Mass?
Lean Body Mass (LBM), also called Fat-Free Mass, is your total body weight minus all fat. It includes muscle, bone, organs, skin, and water. LBM is a better indicator of fitness than total weight because it measures what's actually metabolically active.
Why track LBM?
Tracking LBM helps you understand if you're gaining muscle or losing it during weight loss. The goal is usually to maintain or increase LBM while losing fat. More lean mass also means a higher metabolism.
