Male 70 kg at 175 cm: Boer LBM ≈ 55.9 kg (80% lean mass, 20% fat mass).
Key insights to remember
Lean body mass consists of muscle, bone, organ tissue, fluids, and essential fat.
The Boer equation is often considered the standard for drug dosing calculations in clinical settings.
LBM is a better predictor of basal metabolic rate (BMR) than total body weight.
Increasing lean body mass through strength training elevates daily calorie burning at rest.
How to interpret your results?
Lean Mass (LBM)
Total weight of all body components excluding non-essential adipose fat.
Fat Mass
