Bu hasapçy hakda
A lean body mass (LBM) calculator estimates the weight of everything in your body that is not fat — muscle, bone, organs and water — from your height, weight and sex. It uses the Boer formula by default, a well-validated prediction equation, with James and Hume as alternatives, and reports the remaining fat mass and body-fat percentage alongside it.
For a 175 cm, 75 kg man the Boer formula is 0.407 × 75 + 0.267 × 175 − 19.2 ≈ 58 kg of lean mass. Fat mass is then 75 − 58 = 17 kg, or about 23% body fat. Women use different constants (0.252 × weight + 0.473 × height − 48.3) because they carry proportionally more essential fat. The tool clamps results so lean mass never exceeds total weight.
Lean body mass is useful for setting protein and calorie targets, tracking whether a diet is costing you muscle, and, in medicine, for scaling some drug doses. Because these are prediction equations rather than a body scan, they are estimates — a DEXA scan or hydrostatic weighing is more precise for very lean or very heavy people. This is general information, not medical advice.

Resistance training with enough protein (often 1.6-2.2 g/kg) and adequate total calories builds muscle, the main component of lean mass. Tracking LBM during a diet helps you confirm that you are losing fat rather than muscle.
Lean body mass with muscle mass the same?
Haýal. Lean body mass includes muscle plus bone, organs, connective tissue and body water; scheletal muscle is only a part of it. Muscle is the part you can grow with training.
