Bioelectrical impedance analysis (BIA) utilizes a handheld device that determines body composition by measuring the “resistance to the flow of an electric current through the body tissue.”

Underwater weighing uses “water displacement and how much area your body takes up in space” to gauge your body-fat percentage. Many believe that this gives the most accurate measurement.
