## What is the Lean Body Mass Calculator?

The weight your body contains, excluding your fat weight, is known as lean body mass. Everything else in a body with no fat but has weight. Like all the osseins, muscles, glands, organs, skin, and blood is included in the lean body.

If you are struggling with losing weight, then calculating the lean body is essential. By observing your LBM (Lean Body Mass), you can find to what extent you are dropping your muscle. Because only losing muscles means you aren't taking a healthy diet. Calculating your LMB also helps you maintain the fat ratio in your body.

**What is the Boer formula?**

There are various equations to obtain LBM, and they differ for men and women. However, we will use the most common and most accurate LMS **formula driven by Sir Boer**...That is why it is also known as the **Boer formula**.

**For Men**

LBM = 0.407

weight + 0.267 * height - 19.2

**For Women**

LBM = 0.252 * weight + 0.473 * height - 48.3

Whereas, But, it will get more straightforward if you already know about your fat concentration (%). By using the simple formula, you can get your precise Lean Body Mass.

LBM = weight of the body - (Weight of the body * Body Fat %)

### Example

For a more transparent and precise understanding, let's have an example below:

Suppose a man, has a height of 165 cm and a weight of 50 kg. Find the lean body mass of this man.

**Given data**

height = 165cm

weight = 50kg

**To Find**

LBM = ?

**Solution**

To find the LBM, we will use the Boer formula:

LBM [Men] = 0.407 * weight + 0.267 * height - 19.2

Putting values in the above equation

LBM [Men] = 0.407 * 50 + 0.267 * 165- 19.2 = 45.205

So the LBM of this man is approximately equal to 45kg.
