What is lean body mass?

Lean body mass is the weight of your body if you didn’t have anybody fat; it includes all of your organs, bones, muscles, blood, and skin, as well as everything else that isn’t fat but has mass.

If you’re attempting to reduce weight, knowing your lean body mass is very vital. You can keep track of how much muscle you’re losing by looking at your LBM. If you’re merely losing muscle, the consequences of your diet may be discouraging, as muscle loss frequently results in an unattractive appearance. Knowing how to calculate your lean body mass can also help you determine how much fat you should shed and what your body fat percentage will be once you’ve done so.

How to calculate lean body mass

There are several formulas for calculating lean body mass (and they vary between sexes as well). The Boer formula, which is claimed to be the most accurate, is what we’re employing.

LBM (men) = 0.407 * weight [kg] + 0.267 * height [cm] - 19.2

LBM (women) = 0.252 * weight [kg] + 0.473 * height [cm] - 48.3

However, if you know your fat concentration, you can determine your exact LBM, according to this simple formula:

Lean Body Mass = Body Weight - (Body Weight * Body Fat %)

You will need to:

  1. Measure your body weight
  2. Multiply your body weight by the fat percentage
  3. Subtract the result from your body weight

How to use LBM calculator

A lean body calculator is a helpful tool for determining your lean body mass. All you have to do is enter in your weight and height. The calculator will then calculate two different versions of LBM, one for males and one for women.

Consider the following scenario:
50 Pounds
165 cm tall

If you’re a guy, you’ll need around 45 kg of NBM, and if you’re a woman, you’ll need about 42 kg. Genetics has a role in gender differences. The male body has greater muscle, whereas the female body has more body fat by nature.
