There are a few reasons why you might want to use a lean body mass calculator. Have you ever wondered why slim but muscular people may weigh more than plump ones? Some people say "muscle weighs more than fat", but is it really true? If so, what does the muscle weight depend on? If you want to answer these questions, you should know how to calculate lean body mass (LBM).
You'll find out:
Lean body mass contains everything except body fat; that means it counts all the organs, bones, muscles, blood and skin, and everything else which is not fat but has mass.
It is particularly important to know your lean body mass when you are trying to lose weight. By watching your LBM you can control if you are losing only body fat and no muscle. Otherwise, the effect of your diet may be very disappointing, as losing muscle very often results in unpleasant appearance.
There are multiple lean body mass equations (and they vary for both sexes, too). We're using the Boer formula, which is said to be the most accurate.
LBM (men) = 0.407 * weight + 0.267 * height * 100 - 19.2
LBM (women) = 0.252 * weight + 0.473 * height * 100 - 48.3
However, if you know your fat concentration, you can determine an exact LBM, according to this simple formula:
Lean Body Mass = Body Weight - (Body Weight * Body Fat %)
You will need to:
Lean body calculator is a useful tool which enables you to find your lean body mass. You simply need to type in your weight and height. Then, the calculator will estimate two versions of LBM - the first one for men and the second one for women.
Let's take an example:
The calculator shows about 45 kg of NBM if you are a man and about 42 kg if you are a woman.
Using LBM Calculator you can also find your body fat percentage. However, instead of subtracting the values, you can check our body fat calculator or ideal weight calculator.
In order to find out if your body fat percentage is proper or not, you can use the BMI calculator. This tool calculates if you are underweight, overweight or just right. As LBM is closely connected with metabolism I would also recommend basal metabolic rate calculator.
