LBM = total weight × (1 − body fat%). Boer formula (men): LBM = 0.407W + 0.267H − 19.2; women: 0.252W + 0.473H − 48.3. Used for drug dosing, anesthesia, and fitness tracking. Increasing LBM raises BMR since muscle burns more calories at rest than fat. Track LBM (not just weight) to distinguish fat loss from muscle loss during a diet.
