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.
Thatâs because our first woman has 99 pounds of lean body mass and our second woman has 117 pounds of lean body mass. While they share the same total bodyweight, the leaner woman will have a higher calorie maintenance. This is primarily because muscle requires more energy to maintain than bodyfat.
