💪 Clinical Anthropometric Body Profiler
Lean Body Mass Calculator
Estimate your fat-free lean tissue weight using validated clinical equations (Boer, James, and Hume) to optimize protein dosing and athletic training.
Body Metrics
Estimated Lean Body Mass (Boer Standard)

💡 Optimal Protein Dosing Benchmark:
Athletes aiming to maximize muscle hypertrophy should consume 100g to 138g protein/day (1.6 - 2.2g per kg of LBM).
Clinical Lean Body Mass Equations
Lean Body Mass equations use weight ($W$ in kg) and height ($H$ in cm) to estimate non-adipose tissue:
- Boer (Men): $\text{LBM} = 0.407W + 0.267H - 19.2$
- Boer (Women): $\text{LBM} = 0.252W + 0.473H - 48.3$
- James (Men): $\text{LBM} = 1.1W - 128 \times (W / H)^2$
