Lean body mass is what your body will weigh if you do not have any fat. This approach counts all organs, bones, skin, blood, and everything else that isn’t fat but contains mass.

If you’re losing weight, the consequence of your daily diet might be somewhat unsatisfactory, as shedding muscle frequently leads to an unpleasant look. Understanding how to calculate your lean body mass also determines how much fat you need to shed and your body fat percentage. It’s considerably more accurate to consider your LBM when determining your body weight.

Put another way; it is the burden of muscles, bones, other body tissues, and limbs with no fat. As you understand what lean body mass is, you may have a notion about what’s essential in your weight loss assignment.

How to Calculate Lean Body Mass?

The lean body mass calculator is easy to calculate your lean body mass. Simply enter your height, weight, and gender, and the calculator will do the rest.

You can also use our Body Mass Index Calculator (BMI) to estimate your lean body mass. Enter your height and weight, and the calculator automatically generates your BMI. You can use the BMI chart to find your estimated lean body mass.

For those who want a more accurate estimation, you can use our Lean Body Mass Formula.

Just follow these steps:

1. First, determine your body fat percentage. You can use a skinfold caliper or bioelectrical impedance analysis (BIA).

2. Next, multiply your body fat percentage by your total weight. This will give you your estimated fat mass.

3. Finally, subtract your fat mass from your total weight. The result is your lean body mass.

For example, if you weigh 200 pounds and have 20% body fat, your estimated fat mass would be 40 pounds (200 x 0.20 = 40). Your lean body mass would be 160 pounds (200 – 40 = 160).
