Lean Body Mass Calculator

A lean body mass calculator is useful for a variety of reasons. Have you ever pondered why skinny people who are strong appear to be heavier than chubby people? “Muscle weighs more than fat,” we’ve all heard it said, but is it true? What factors influence muscle mass? You should be able to calculate lean body mass if you want an answer to these questions (LBM). In this article, You’ll discover:

  • What is the definition of lean body mass?
  • What is the formula for calculating lean body mass?
  • What is the LBM Calculator and how do I use it?

All organs, bones, muscles, blood, and skin, as well as anything else that isn’t fat but has mass, are considered part of your lean body mass.

Knowing your lean body mass is crucial if you’re trying to lose weight. Keeping track of your LBM can help you keep track of how much muscle you’re losing. If you’re merely losing muscle, the effects of your diet may be underwhelming, because muscle loss is frequently accompanied by an unattractive appearance.

Being knowledgeable on how to calculate your lean body mass can help you determine how much fat you should shed and what your body fat percentage will be afterward. Using your LBM instead of your real weight is far more precise.

Lean Body Mass Calculator Formula

There are various equations that may be used to calculate lean body mass (and are different depending on gender). Boer came up with a formula that is actually the most précised formula for calculating lean body mass.

0.407 X weight in kg + 0.267 x height in cm–19.2 = Lean body mass (for men)

0.252 X weight in kg +0.473 x height in cm -48.3= Lean body mass (for women)

You can calculate your exact LBM using this simple method if you know your fat concentration:

Body weight–(body fat percentage x body weight)

You must complete the following tasks:

  • Weigh yourself.
  • By multiplying your body weight by your fat percentage, you may get a rough estimate of how much fat you have on your body
  • Take the result and subtract it from your total body weight.

What Is The Best Way To Use A Lean Body Mass Calculator?

The lean body mass calculator can assist you in determining your lean body mass. Only your height and weight are needed. However, the calculator will then produce two different versions of lean body mass, one for women and the other for men.

Consider the following scenario: 50 pounds 165 cm tall

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

More Factors to Be Determined By Using Lean Body Mass Calculator

You may find your body fat percentage with the LBM Calculator. Furthermore, you can use our body fat calculator or optimum weight calculator instead of subtracting the numbers.

The BMI calculator can determine whether your body fat percentage is healthy. This calculator determines if you are underweight, overweight, or in the middle of the scale. We recommend using a basal metabolic rate calculator because LBM is directly linked to metabolism. It calculates number of calories you would require if you spent the entire day resting based on your age, height, weight, and gender. However, it’s a great way to figure out how well your metabolism is working.

Aging and Lean Body Mass

Muscle tissue deteriorates as we become older. Muscle mass declines 3–8% every decade beyond the age of 30, according to a review article by Volpi et al. on how muscle tissue change with age. This rate of reduction is considerably higher after the age of 60.

Because of the pervasive availability of high-energy refined/processed junk food, there is a predisposition toward inactivity as we age, which may speed muscle loss and a fall in metabolic rate–as well as fat gain.

How Do I Increase My Lean Body Mass?

Look no further than exercise and food if you want to keep your lean mass.


Strength training (also known as weight lifting or progressive resistance training) puts your body under stress in order to promote muscle growth. By accumulating the amount of weight you lift over time, your body will become stronger and larger. Two to three workouts per week can aid in the development of muscle and/or the prevention of muscle loss.

To gain muscle, you can do a variety of resistance exercises.

  • Pilates 
  • Bands of resistance
  • Yoga
  • And many more.

Summary of Lean Body Mass Calculator

Based on your gender, height, and weight, our lean body mass calculator will calculate how much lean muscle tissue and fat mass you have.

It’s crucial to remember that the quantity of muscle and fat you have depends on a variety of factors (such as exercise volume, dietary habits, physical health condition, hormones, and so on) and thus prediction equations have a small margin of error.

Please read the pages above after you’ve used the calculator to get a better idea of your lean body mass.


What Is The Recommended Amount Of Lean Mass For Me?

Women’s lean mass ranges between 70 and 75 percent, whereas men’s lean mass ranges between 75 and 85 percent.
However, lean body mass varies by age, hormone status, exercise volume and intensity, injury and immobilization, and other medical conditions that may affect lean tissue.

What Does It Mean To Have A Lot Of Lean Muscle Mass?

Lean body mass is just anything in your body that isn’t fat mass (i.e., skeletal muscle, organs, ligaments, tendons, bones).
White fat (i.e., fat stored beneath your skin and around your organs), brown fat (i.e., heat production), beige fat (i.e., a combination of the two), and essential fat (i.e., a mix of the two) make up your fat mass (in your brain, nerves, and membranes).
