Lean Body Mass Calculator - Check Lean Body Mass (LBM)

Lean Body Mass Calculator Overview

• The lean Body Mass calculator helps you find your body's lean body mass (LBM) value to stay healthy.
• "Lean body mass" may sound like the amount of muscle you have, but that's not quite true. 
• More accurately, it's the amount of weight you carry that isn't body fat.
• Your LBM includes muscle, but also bones, water, connective tissue, and stored-up glycogen and other substances.

 

Steps To Calculate Lean Body Mass

1. Enter Your Gender
2. Enter Your Height (cm) & Weight (kg)
3. Check the Result of Lean Body Mass

 

Lean Body Mass Calculator Formula

 

Here is a formula for Lean Body Mass as per Boer For All

LBM (men) = 0.407 * weight [kg] + 0.267 * height [cm] - 19.2

LBM (women) = 0.252 * weight [kg] + 0.473 * height [cm] - 48.3

Lean Body Mass Formulas for Adults

 

The Hume Formula

For Males:

eLBM = 0.32810W + 0.33929H - 29.5336

For Females:

eLBM = 0.29569W + 0.41813H - 43.2933

 

The Boer Formula

For Males:

eLBM = 0.407W + 0.267H - 19.2

For Females:

eLBM = 0.252W + 0.473H - 48.3

 

Lean Body Mass Formula for Children

 

The Peters Formula

• The author suggests that this formula is applicable to children aged 13-14 years old or younger. 
• The formula is used to compute an eLBM based on an estimated extracellular volume (eECV) as follows:

eECV = 0.0215·W0.6469·H0.7236

eLBM = 3.8·eECV

 

In the formulas above, W is the body weight in kilograms and H is the body height in centimeters.

 

Calculate Lean Body Mass

• Lean body mass is what your body would weigh if you didn't have any body fat; that means it counts all the organs, bones, muscles, blood and skin, and everything else which is not fat but has mass.
• If you are only losing muscle, the effect of your diet may be very disappointing, as losing muscle very often results in an unpleasant appearance. 
• Knowing how to calculate your lean body mass also helps you decide how much fat you should lose and what your body fat percentage will be after that. 
• It is particularly important to know your lean body mass if you are trying to lose weight. 
• By watching your LBM you can monitor how much muscle you are losing. 
• It is much more accurate to consider your LBM than your body weight.

 

Body Muscle mass percentage averages for men

Age	Muscle mass percentage
18–35	40–44
36–55	36–40
56–75	32–35
76–85	< 31

 

Body Muscle mass percentage averages for women

Age	Muscle mass percentage
18–35	31–33

56–75	27–30
76–85	< 26

 

 

Benefits of Higher-than-Average Muscle Mass

• Generally, greater muscle mass has positive health effects.
• As you get older, you naturally lose muscle mass. 
• This age-related muscle loss, also called sarcopenia, begins at age 30. 
• You continue to lose 3 to 5 percent of muscle mass every decade, which reduces physical function and increases your risk of injury.
• But if you have high muscle mass, you can slow down muscle loss and protect your physical ability.
• Skeletal muscle also improves your overall metabolism.
•  Compared to fat, skeletal muscle burns more calories at rest.
• Additionally, greater muscle mass is associated with longevity. 
• A study found that older adults with more muscle mass live longer than those with less.

 

Side effects of Higher than Average Body Muscle Mass

• If you have higher-than-average muscle mass, it may be difficult to find clothes that fit well. 
• You’ll also need to eat more calories to feel full, which can become inconvenient and expensive.
• Some people say having greater muscle mass reduces their flexibility and ability to jump or run.

 

Importance Of Lean Body Mass - LBM Calculator

 

• LBM Calculator can also find your body fat percentage. 
• However, instead of subtracting the values, you can check our body fat calculator or ideal weight calculator.
• In order to find out if your body fat percentage is healthy or not, you can use the BMI calculator. 
• This tool calculates if you are underweight, overweight, or just right. 
• As LBM is closely connected with metabolism we also recommend a basal metabolic rate calculator. 
• It uses your age, height, weight, and gender to estimate how many calories you would need if you were to spend the whole day resting. 
• It's an excellent indicator of your metabolism levels. 
• You can also determine your body composition that adjusts for skeletal mass, by using our body frame size calculator.

 

Lean Body Mass Vs Fat Free Mass

• Lean body mass and fat-free mass are often used interchangeably. 
• While this is unlikely to cause issues in most cases, the two are not exactly the same.
• Lean body mass includes the combined mass of bones, muscles, water, ligaments, tendons, and internal organs. 
• Internal organs include some essential fat and the mass of this fat is included in the measurement of lean body mass. 
• Although internal organs also have surrounding subcutaneous fat, this fat is not included in the measurement of lean body mass.
• Fat-free mass is calculated as the difference between total body mass and all fat mass including essential fat. 
• This is the difference between fat-free mass and lean body mass. Subtracting the mass of essential fat from lean body mass yields fat-free mass. 
• The difference between lean body mass and fat-free mass amounts to approximately a 2-3% difference in men and 5-12% difference in women.

Tips For Lean Body Mass

• Although Lean body mass declines with age, it’s never too late to build muscle through exercise and diet.
• Exercise and good nutrition will also help preserve muscle mass as you get older.

 

Exercise

• Strength training, or weight training, is the best way to build muscle mass. 
• This type of exercise strengthens your muscles by forcing them to work against resistance.

 

You can

• Do bodyweight exercises, like pushups
• Do resistance band exercises
• Lift free weights, like dumbbells or soup cans
• Use weight machines
• Do high-intensity interval training (HIIT)
• Do Pilates

 

It’s recommended to do two or three strength training sessions each week. Cardio is still important, though. Aerobic exercises, like jogging or dancing, supports muscle growth and slows age-related muscle loss.

 

Diet

• Gaining and keeping muscle mass also depends on good nutrition. 
• This includes eating enough nutrient-dense calories to fuel your body.
• Protein, which helps build and repair muscle, is particularly important. 
• The amount of protein you need depends on your level of physical activity. 
• Generally, 10 to 35 percent of your daily calories should come from protein

 

Examples of high-protein foods include:

• Beef
• Poultry
• Fish
• Eggs
• Beans
• Nuts

 

You also need enough carbohydrates to fuel your muscles. If you’re strength training two or more times per week, carbohydrates should make up at least 50 percent of your daily calories. Additionally, an adequate intake of fat, vitamins, and minerals is necessary for building muscle.
