What is the Lean Body Mass Calculator & How does it work?
Lean Body Mass (LBM) is the total weight of a person excluding fat. It's crucial for understanding muscle mass and overall health. The Boer, James, and Hume formulas are commonly used to estimate LBM based on body weight, height, and gender.
The Boer formula is particularly accurate for Caucasians, while the James formula is more suitable for Asian populations. The Hume formula provides a general estimation without considering ethnicity. Each formula helps in assessing body composition, which is vital for fitness and medical evaluations.
$$LBM_{Male} = 0.407 \cdot W + 0.267 \cdot H - 19.2$$
LBM = Lean Body Mass, W = Weight (kg), H = Height (cm)
