To measure the relative proportion of fat and lean tissue which is lost requires a direct measurement of body accu measurebody fat caliper composition. The most accurate methods to measure body fat are difficult or expensive or both! The classical method involves calculating body density. This requires a measurement of body weight and body volume. Weight is easily measured, but volume is more complex. accu measurebody fat caliper Body volume is usually measured by water displacement (Archimedes principle), which involves totally submerging the subjects underwater. Only about ten systems accu measurebody fat caliper to measure body density are available in the UK, all in specialised research centres. Research laboratories also use measurements of the body’s water content to estimate the amount of lean and fat tissue. Fat does not contain any water whereas lean tissue is about 73% water.
