Understanding Your Results
Lean Body Mass (LBM) is your body weight minus your body fat. It includes muscle, bone, organs, and water. A higher LBM generally indicates better physical fitness and metabolic health.
The Lean Body Mass Calculator is a helpful tool that shows how much of your body weight comes from everything except fat. This includes your muscles, bones, organs, skin, and fluids. It gives you a better understanding of your true body composition and helps you track progress if you're trying to gain muscle or lose fat.
What is Lean Body Mass?
Lean Body Mass (LBM) is your total body weight minus fat. It's also known as fat-free mass. Knowing your LBM can help you improve your workouts, diet, and overall health goals.
How is Lean Body Mass Calculated?
There are different formulas to estimate LBM. One of the most common is the Boer formula:
For Men: LBM = (0.407 × weight in kg) + (0.267 × height in cm) - 19.2
For Women: LBM = (0.252 × weight in kg) + (0.473 × height in cm) - 48.3
The calculator uses this formula to give you a quick result. You just need to enter your weight, height, and gender.
Example
Let’s say a man weighs 75 kg and is 175 cm tall:
LBM = (0.407 × 75) + (0.267 × 175) - 19.2
LBM = 30.525 + 46.725 - 19.2 = 58.05 kg
This means his lean body mass is about 58.05 kg.
Why is Lean Body Mass Important?
Tracking LBM is useful for athletes, people trying to lose fat, or those looking to build muscle. Unlike total body weight, LBM tells you how much of your body is strong and healthy. It can also help avoid mistakes like losing muscle during a weight loss program.
