Frequently asked questions
What is the difference between LBM and muscle mass?
Muscle mass counts only skeletal muscle, while LBM also includes bone, organs, skin and body water. That is why LBM is always the larger of the two figures, typically by a wide margin.
Why does LBM matter when dieting?
Aggressive dieting strips muscle as well as fat, and losing LBM lowers the number of calories you burn at rest. Tracking LBM shows whether weight loss is coming from fat or from tissue you would rather keep.
