Lean Body Mass vs. Muscle Mass. Lean Body Mass (also sometimes known as simply âlean mass,â likely the source of the word âlean muscleâ) is the total weight of your body minus all the weight due to your fat mass. It includes the weight of all your organs, your skin, your bones, your body water, and your muscles.
Body fat calculations for men include using a scale that makes use of pounds and a tape measure that uses inches. To calculate your lean body mass use your waist measurement and exact body weight at (1.082 x weight) â (4.15 x waist.) To determine body fat percentages versus lean body mass use this formula: body weight â lean body mass x 100 / 150. This will give you a percentage. For example if your body weight is 150 and your lean body mass is 125 you have a body fat percentage of 16.66. To calculate the body fat for women use a tape measure that uses inches and a scale that uses pounds.
