What is a Lean Body Mass?

A Lean Body Mass is the factor between the total body weight and body fat.
So a lean body mass means counting the mass of all organs. It doesn't include body fat. So the total weight of all organs, including the bones, blood, muscles, and skin.

The Total Percentage of an LBM cannot be calculated directly. It ranges between 60-90% of a person's total body weight.

Men have a good proportion of LBM compared to Women. The proportion of certain dosages, like anesthetic agents, but most importantly, dissolving in water drugs, is highly dependent on the LBM.

Even more, the LBM value is a significant value for medical purposes. The LMB needs to be considered in terms of fitness and everyday routine. The main concern here is Body Fat. 

There are many formulas to calculate the LBM. The Calculator provides an approximate value of a person's LBM.

What is the difference between Fat-Free Body Mass and Lean Body Mass?

First, it is important to understand that Lean Body Mass and Fat-Free Body Mass are completely different things. 
Calculating the LBM includes non-fat tissues, bones, muscles, and other components. 
Apart from this, the non-sex-specific essential fat comprises 3-4% of men's bodies and 5-7% of women's. The Internal Organs have a surrounding subcutaneous fat. The fat is not measured while Calculating the Lean Body Mass.

Fat Body Mass is measured as the differing factor between the total body mass and the fat mass. It is the major difference between fat-free mass and Lean Body Mass.
The mass of essential fat from Lean Body Mass is subtracted, yielding the fat-free mass.

What are the ways to measure Lean Body Mass?

The Calculator can provide the Lean Body Mass value. But the approximate and correct value by the Calculator may be flawed. However, the benefit of using the Lean Body Mass Calculator is less expensive and nearly accurate.

While the other expensive way to calculate Lean Body Mass is to visit a Doctor or a fitness expert, some of them include DEXA and MRIs. Most of them use the DEXA as it is easy, accessible, and convenient.

The other ways to count lean body mass are total body mass weight, total body counting, and others. These methods have accuracy in people who are overweight and obese. Sometimes these ways are also suggested by Doctors to treat any issue related to the patient's health.


The Lean Body Mass Calculator can calculate the LBM of a person. Instead of using the formula and equation, one can directly refer to the Calculator and get an approximate value.
