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).

Hydrostatic weighing, also referred to as underwater weighing, hydrostatic body composition analysis and hydrodensitometry, is a technique for measuring the density of a living person's body. It is a direct application of Archimedes' principle , that an object displaces its own volume of water.
A 1998 study suggested that energy restriction and weight loss, for example a 4- to 12-week period of diet and exercise was beneficial. [1] A small study of 11 Asians with MONW published June 2018 found that moderate weight loss through dieting reduced their cardiometabolic risk per improved body composition, lipid profile, and insulin sensitivity.
