What is lean body mass?
Lean body mass (LBM) is all body weight that isn't fat: muscles, bones, organs, water, and tissues. It's an important indicator of metabolic health and physical condition, as muscle burns more calories at rest.
Why is it important?
Lean mass determines your basal metabolism, functional strength, and athletic capacity. Preserving it during weight loss is crucial to keep metabolism active and avoid the rebound effect.
How to increase lean mass
Strength training is the most effective way to increase lean mass. Combine it with sufficient protein (1.6-2.2g/kg), adequate rest, and a small caloric surplus to gain muscle.
