The myth that muscle is heavier than fat likely stems from a difference that does exist between fat vs muscle: density. Muscle is denser than fat, which means that if you have one pound of each ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

Experts explain the relation of fat and muscle on weight, how body composition effects overall health, and tips for how to gain muscle and lose fat.
In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8] Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent , and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to ...
The density of mammalian skeletal muscle tissue is about 1.06 kg/liter. [11] This can be contrasted with the density of adipose tissue (fat), ...
BMI vs. Body Fat Percentage. BMI and body fat percentage are both ways of determining whether a person has a healthy weight or not. A high BMI can indicate a high body fat percentage, but it’s ...
Prior to the adoption of DXA, the most accurate method of estimating body fat percentage was to measure that person's average density (total mass divided by total volume) and apply a formula to convert that to body fat percentage. Since fat tissue has a lower density than muscles and bones, it is possible to estimate the fat content.
While my BMI and skeletal muscle weight were both in healthy ranges, my body fat percentage was slightly over the healthy limit. I also had the maximum healthy limit of visceral fat , fat stored ...
