The formulas to calculate lean body mass are:
\(\text{LBM (men)} = 0.407 \times \text{weight} + 0.267 \times \text{height} - 19.2\)
\(\text{LBM (women)} = 0.252 \times \text{weight} + 0.473 \times \text{height} - 48.3\)
Example 1 (Men):
Calculation:
\(0.407 \times 70 + 0.267 \times 175 - 19.2 = 28.49 + 46.725 - 19.2 = 56.015 \text{ kg}\)
Example 2 (Women):
Calculation:
\(0.252 \times 60 + 0.473 \times 165 - 48.3 = 15.12 + 78.045 - 48.3 = 44.865 \text{ kg}\)
