Using the Hume Formula, the Lean Body Mass of a male is calculated in two components. The first and the second component are multiplied to give the Lean Body Mass of a female. Meanwhile, the weight in kilograms is divided by the height in centimeters and the answer is squared to obtain the second component. Then, 148 is subtracted from the arrived number to give the first component. Likewise, the Lean Body Mass of a female is calculated by first multiplying the weight in kilograms with 1.07. The first and the second component are multiplied to give the Lean Body Mass of a male. Then, 128 is subtracted from the arrived number to give the first component. Using the James Formula method, Lean Body Mass of a male is calculated by first multiplying the weight in kilograms with 1.1. Male : (1.1 * weight in kg) - 128 * (weight in kg / height in cm) 2įemale : (1.07 * weight in kg) - 148 * (weight in kg / height in cm) 2 Finally, 48.3 is subtracted from the gross result to give the Lean Body Mass of a female. The two values are added to get the gross result. Likewise, the Lean Body Mass of a female is calculated first by multiplying the height in centimeters with 0.473 and multiplying the weight in kilograms by 0.252. Finally, 19.2 is subtracted from the gross result to give the Lean Body Mass of a male. Using this method, the Lean Body Mass of a male is calculated first by multiplying the height in centimeters with 0.267 and multiplying the weight in kilograms by 0.407. The Lean Body Mass can be calculated using three different formulas as set forth below to find the lean body mass.
