Ways to Measure Body Fat

Underwater Weighing

Since muscle is much denser than fat, body density can tell us a lot about body composition. With underwater weighing, the subject is submerged and their density is calculated to estimate body composition. The downside, you have to get wet, and you need to be submerged underwater which may not be comfortable for some. However, underwater weighing is an extremely accurate measure of body composition if you don’t mind going under.
