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.
BMR= Lean body mass (lbs) x 13.8 calories. You can obtain your lean body mass from body fat measurements. Calculate lean muscle mass vs. fat mass: Body fat % x scale weight= fat mass.
