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).

The air volume before you get inside the chamber is compared to the air volume once you’re inside to determine bone density, body fat and muscle mass. Kateryna Onyshchuk / iStock.
Ectopic fat is the storage of triglycerides in tissues other than adipose tissue, that are supposed to contain only small amounts of fat, such as the liver, skeletal muscle, heart, and pancreas. [1] This can interfere with cellular functions and hence organ function and is associated with insulin resistance in type-2 diabetes. [ 46 ]
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.
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.
Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
