<P> Bioelectrical impedance analysis ( BIA ) is a commonly used method for estimating body composition , and in particular body fat . Since the advent of the first commercially available devices in the mid-1980s the method has become popular owing to its ease of use , portability of the equipment . It is familiar in the consumer market as a simple instrument for estimating body fat . BIA actually determines the electrical impedance , or opposition to the flow of an electric current through body tissues which can then be used to estimate total body water ( TBW ) , which can be used to estimate fat - free body mass and , by difference with body weight , body fat . </P>
