Lean Body Mass Calculator
What is Lean Body Mass?
Lean body mass (LBM) is how much your body would weigh without any body fat. It takes into account the weight of bones, muscles, organs, blood, skin, and every other part of your body that isn’t fat but has mass.
Using a lean body mass calculator helps you monitor how much muscle you’re losing, decide how much fat you want to lose, and what your body fat percentage will look like afterward.
Looking at your lean body mass is much more accurate than only measuring your body weight.
How do I Calculate Lean Body Mass?
Calculating your lean body mass relies on complex equations, but if you already know your fat concentration, you can use this simple formula:
Lean Body Mass = Body Weight - (Body Weight * Body Fat %)
Most of us don’t know our body fat percentage off the top of our heads, so we’ve created a lean body mass calculator to make it easy to find your LBM.
