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.
Average Bone Percentage. According to âAdvanced Human Nutrition,â a lean man is theoretically made up of about 15 percent bone, 45 percent muscle and 15 percent fat. A lean woman is made up, on average, of 12 percent bone, 35 percent muscle and almost 30 percent fat. Protect your bone health by eating fruits and vegetables, consuming protein, sodium and caffeine only in moderation, and by staying active, recommends the National Osteoporosis Foundation.
