Calculating Body Mass is now made easy with this Lean Body Mass Calculator. This LBM calculator designed in a way that everyone can use it by putting in values like your weight, gender, and height. This Lean Body Mass Calculator tells you not just the LBM for various categories but also tells about your body fat percentage. For a weight-conscious person, this LBM Calculator is a very handy tool.
You might have seen people who are fat but not muscular, and if you compare their body weights, you will find out that fat person has lesser weight than the muscular man. A fat person looks bulky due to extra fat in the body, while muscles possess more volume than the weight, and that’s why a person with muscles looks smarter but still has good weight; that’s because this person has a more lean body mass than the body fat. And now you know why it is important to know about your lean body mass.
In very simple words, the lean body mass is the weight of your body after deducting the weight of your body fat. In other words, it’s the weight of muscles, your bones, other body organs, and limbs without fat. Now as you know what is lean body mass, you might have got the idea of what is important in your mission of weight loss.
The extra body fat not just disfigure your body, it is also dangerous for your health and smooth performance of your daily body functions. So if you will calculate how much lean body mass and body fat you have, you can plan your diet and workout accordingly to improve your lean body mass and to reduce your body fat.
Usually, Lean Body Mass (LBM) rages from 60 to 90 percent of body weight. A man with less than 75 percent LBM is said to be unhealthy, and for a woman, it is less than 68 percent. Athletes often have lean body mass (LBM) between 84 and 94 percent for men and 81 and 91 percent for women, which is said to be normal for trained individuals, although it is lower than the average for healthy people. Studies depict that, it is not healthy, however, for a woman to have less than 8% body fat or a man to have less than 5% body fat.
Calculating Lean Body Mass is different for different gender because the body structure and requirements are different for males and females. Normally, female body needs to have more body fat than males so the lean body mass will be lower than males. Let’s have a look how to calculate lean body mass for male and females using lean body mass formulas, but before that let we tells you about the main equation of LBM or (eLBM).
LBM = BW – BF
The LBM formula’s that are taken into account for calculating LBM are as follows:
0.407 × weight[kg] + 0.267 × height[cm] – 19.2
0.252 × weight[kg] + 0.473 × height[cm] – 48.3
1.1 × weight[kg] – 128 × ( weight[kg] / height[cm] ) 2
1.07 × weight[kg] – 148 × ( weight[kg] / height[cm] ) 2
0.32810 × weight[kg] + 0.33929 × height[cm] – 29.5336
0.29569 × weight[kg] + 0.41813 × height[cm] – 43.2933
The peters equation is used to calclate LBM of children (up to 13-14 years old) and this equation is based on an estimated extracellular volume (eECV) as given:
eECV = 0.0215·W0.6469·H0.7236
eLBM = 3.8·eECV
Now from the formula’s, you can see how different the lean body mass is for males and females and children. And if you feel that you can’t remember these equations, you always have the option of using this simple and easy to use LBM calculator to calculate your lean body weight.
As you know, lean body mass definition and you have also learned how to calculate lean body mass, and now you need to know how lean male body or female body is perfect or satisfactory. To know about how lean male body or female body should you, you can consult lean body mass chart given below. And if according to chart, you have less lean body mass and more of body fat, you need to try lean body workout to come back to perfect figures.
You just have to fill the designated fields of this simple lean mass calculator to attain your result. You can readily calculate LBM within just four simple steps:
Generally, women posses more body fat as compared to men even if they have the same body mass index (BMI). Studies reveal that women need more body fat % for them to bear children. That’s the basic reason why they often have a less lean body mass as compared to men. Average women would have LBM between 69 to 75%, and for men, LBM is between 76 to 82%.
For many individuals, LBM range from 60 to 90% of their body weight. If a female has a lean body mass (LBM) percentage lower than 68%, then she’s considered unhealthy. The same for a man, if he has an LBM percentage lower than 75%.
Typically, athletes who workout and train to build muscles, they have an LBM percentage range between 84 to 94% for men and 81 to 91% for women. Experts referred these ranges “normal” for those who train. You can use the above simple but highly accurate LBM calculator to know in which ranges your LBM is!
Sometimes lean body mass (LBM) also referred to as a “lean mass,” likely the source of the term “lean muscle”, it is the total weight of an individual body minus all the weight due to his/her fat mass.
Lean Body Mass (LBM) = Total Weight – Fat Mass
Unlike “lean muscle”, Lean Body Mass (LBM) the term that correctly uses the word ‘Lean’ as it elaborates the entire weight of individual body minus fat. That’s the reason why it is also said to be as “Fat-Free Mass.”
Remember that the weight of organs will not change much, but bone density is something that will decrease over time and doesn’t significantly affect the weight of your LBM.
The two most major areas to focus on with LBM are body water and muscle mass.
When individuals talk about gaining muscle by consuming more protein or muscle building workouts, what they are really discussing about gaining or building their Skeletal Muscle Mass. However, this is just because of the three major muscle types that are cardiac, smooth, and skeletal. Skeletal Muscle Mass is the only type of muscle that human body can actively grow and develop through proper exercise and nutrition. But, keep in mind, Skeletal Muscle Mass is one part of your LBM or Lean Body Mass and another influencer is water.
No doubt, lean body mass and skeletal muscle mass both has a significant difference, so how you come to know how much each you have?
So, let’s begin with the term what not to do: don’t utilize a scale to determine changes in Skeletal Muscle Mass.
The most prominent method to estimate muscle gain is by using a combination of the number on the scale and advice from fitness magazines.
The problem with using a scale to determine progress is that there are several factors which influence an increase in body weight, a few of which are mentioned below:
Well, the best way to calculate what is happening to your Lean Body Mass (LBM): you just have to getting your body composition analyzed. Keep in mind, without testing your body composition, there will no other way to know what any gain/loss in your body weight is due to.
The methods that will use for body composition analysis will at the minimum divide your body into LBM (this can be indicated to as Fat-Free Mass) and Fat Mass. These methods are:
No doubt, each of them is packed with pros and cons and even accuracy may vary depending on a number of factors, so before taken such methods into account you ought to consult with your doctor!
If you want to get in more depth body composition analysis, then you would have to look to two more sophisticated methods, which include:
These methods tell you how much fat you have and even also differentiate your Skeletal Muscle Mass from your lean body mass (LBM).
Well, it’s to get back to our originally, three statements, let’s take a look!
According to optimistic studies, LBM is composed of all of the muscles, bones, organs, tissues, and water in the body excluding fat. When you hear about lean body mass, you may think of muscle. LBM is something that certainly includes our muscle mass, but even also includes everything else our body is made up of instead of fat. Keep in mind, 3% for men and 11% from women is immensely important for the proper functioning of the body.
These simple things assist you to increase lean body mass faster:
Lean body mass (LBM) is very important as it contributes to looking great or being stronger. Various studies reveal that the greater amount of LBM you have, the greater your Basal Metabolic Rate (BMR) will be. Means, individuals with greater amounts of Lean Body Mass will have greater energy expenditure while doing nothing, assisting to avoid calories imbalances, and ultimately, obesity.
These are the things that help you t get leaner and fitter.
Best foods for gaining lean muscle:
Muscle mass is not the same for every individual and may vary depending on age and fitness level. According to the 2000 study published in the Journal of Applied Physiology, the amount of muscle you have in your body will decrease as your age and dramatically after age 45. And, Classic study in the Journal of Sports Sciences reveals that fitness and type of activity make a difference in muscle mass; remember that bodybuilders having greater muscle percentage as compared to endurance athletes.
Lean body mass is said to be as a measure of the total weight of a person’s bone and muscle minus their fat weight. In another term, lean body mass is referred to as a person’s total weight minus their total fat mass.
In terms of diet, the lean body mass of an individual determines how much protein he/she needs to consume on per day to maintain muscle mass. The evidence of this method comes with the studies in which nitrogen balance is measured in people who relied on a very low-calorie diet (VLCD) to induce weight loss.
