Estimating Lean Body Mass (LBM) in Women - James Formula

Lean Body Mass (LBM) is estimated to determine the dosages of some anaesthetic agents. LBM is calculated by subtracting the body fat weight from total body weight. Lean Body Mass Index in women is less when compared to men. This short tutorial will help you on how to calculate the lean body mass index in women using the James Formula.

The James Formula For Women:
LBM = 1.07 x weight(in kg) - 148 x (weight(in kg) / height(in cm))²

Let us consider an example on how to calculate the lean body mass (LBM) in women using the James Formula with simple steps.
Step 1: Given,
Weight = 60kg
Height = 160cm

Step 2: Applying the values in the formula,
LBM = 1.07 x weight(in kg) - 148 x (weight(in kg) / height(in cm))²
LBM = 1.07 x 60 - 148 x (60 / 160)²
LBM = 1.07 x 60 - 148 x 0.140625
LBM = 43.3875
