Bird "Estimation of lean body mass in children". Hume, R "Prediction of lean body mass from height and weight."."Research on obesity: a report of the DHSS/MRC group" HM Stationery Office 1976 "Estimated lean body mass as an index for normalization of body fluid volumes in man." Am J Physiol 1984 247: F632-5 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. Subtracting the mass of essential fat from lean body mass yields fat free mass. This is the difference between fat free mass and lean body mass. Although internal organs also have surrounding subcutaneous fat, this fat is not included within the measurement of lean body mass.įat free mass is calculated as the difference between total body mass and all fat mass including essential fat. Internal organs include some essential fat and the mass of this fat is included within the measurement of lean body mass. Lean body mass includes the combined mass of bones, muscles, water, ligaments, tendons, and internal organs. While this is unlikely to cause issues in most cases, the two are not exactly the same. Lean body mass and fat free mass are often used interchangeably. In the formulas above, W is the body weight in kilogram and H is the body height in centimeter. The formula is used to compute an eLBM based on an estimated extracellular volume (eECV) as follows: eECV = 0.0215 The author suggests that this formula is applicable for children aged 13-14 years old or younger. Multiple formulas have been developed for calculating estimated LBM (eLBM) and the calculator above provides the results for all of them. To compute body fat, consider using our body fat calculator or ideal weight calculator. For body fitness and routine daily life, people normally care more about body fat percentage than LBM. BMR 370 + (21.6 x Lean Body Mass (kg) ) Lean Body Mass (Weight (kg) x (100- (Body Fat)))/100 Katch-Mcardle BMR Definition This free online calculator is the quickest, simplest way for health conscious individuals to derive their BMR. Some medical exams also use the LBM values. What the Math Looks Like Looking at the math, 227 x 17 percent 38 pounds of fat weight, therefore, 227 38 189 pounds of lean mass. The weight of your bones (skeletal system) comprises 15 percent of your bodyweight. The dosages of some anesthetic agents, particularly water-soluble drugs, are routinely based on the LBM. About 44 percent of this number is pure muscle mass, which in this case, is about 83 pounds. Generally, men have a higher proportion of LBM than women do. basic amount of calories that your body burns to simply keep itself alive). While the percentage of LBM is usually not computed, it on average ranges between 60-90% of total body weight. This basal metabolic rate (BMR) calculator estimates the amount of calories that. This means that it counts the mass of all organs except body fat, including bones, muscles, blood, skin, and everything else. Lean body mass (LBM) is a part of body composition that is defined as the difference between total body weight and body fat weight.
