Body fat meter

From Wikipedia, the free encyclopedia

A Body fat meter is intended to measure the percentage of fat in the human body; various different principles can be used.

One form of meter that is now widely available at a low price, rather than as a clinical tool, is the body fat meter that uses the principle of bioelectrical impedance analysis (BIA) to pass a small, harmless, electric current through the body and make a measurement which, when combined with information on weight, Height, age, and sex, allows body fat as a percentage of body weight to be estimated. The measurement estimates the total volume of water in the body; lean tissue and muscle contain a higher percentage of water than fat, which allows the device to estimate the percentage of fat.

The present version of this article simply states the existence of these meters, with no opinion on the validity of measurements.
