Hydrostatic weighing, also known as underwater weighing, relies on the principle of buoyancy to calculate body density. This method involves comparing an individual's weight in air to their weight when submerged underwater. By determining how much water is displaced by the person's body, the technique can accurately assess body density.

The foundation of this method is based on Archimedes' principle, which states that an object submerged in fluid experiences a buoyant force equal to the weight of the fluid displaced. Since body composition primarily consists of lean mass (muscles, bones, etc.) and adipose tissue (fat), this measurement allows for an estimation of body fat percentage. The denser the body composition, typically indicative of higher muscle mass, the less buoyant the individual will be in water, whereas a higher fat percentage will result in greater buoyancy.

This approach is particularly reliable because it provides a more direct measurement of body density, which can then be used to categorize body composition effectively. Other methods mentioned, like those concerning muscle mass measurement, fat distribution, or general health evaluations based solely on height and weight, do not capitalize on the principles of buoyancy and density assessment that hydrostatic weighing employs.
