How This is Calculated
Lean Body Mass (LBM) = Total Body Weight × (1 − Body Fat % / 100). Fat Mass = Total Body Weight − LBM. LBM includes muscle, bone, organs, and water. Maintaining or increasing LBM during weight loss is associated with better metabolic outcomes and reduced risk of weight regain.
