Boer Formula for Lean Body Mass (Male)
LBM (kg) = 0.407 x Weight(kg) + 0.267 x Height(cm) - 19.2
The Boer formula estimates lean body mass directly from height and weight without requiring a body fat measurement. It is considered one of the more accurate predictive LBM equations.
Example Calculation
A 180 lb, 70-inch tall male.
- 01Weight = 81.6 kg, Height = 177.8 cm
- 02LBM = 0.407 x 81.6 + 0.267 x 177.8 - 19.2
- 03= 33.2 + 47.5 - 19.2 = 61.5 kg (135.6 lbs)
- 04Est body fat = (1 - 61.5 / 81.6) x 100 = 24.6%
