Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. Fat free mass contains two types of water intracellular and extracellular water.

Body fat measurement bioelectrical impedance. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass. Bioelectrical impedance analysis bia determines body composition by running small electrical currents through the body. Intracellular water is that found in the bodys cells. A small current is used to measure the resistance at difference frequencies against the various tissues in the body eg fatlipid has a high resistance to the flow of current therefore shows a high impedance reading. Since the advent of the first commercially available devices. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body.
As the electrical conductivity is different between various bodily tissues eg. Accurate measurement of body water is central to the prediction of body fat from bia. Muscle fat bone etc due to their variation in water content the small electrical current passes through the tissues at different speeds. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body. Therefore if a person is more muscular there is a high chance that the person will also have more body water which leads to lower impedance. Most body water is stored in muscle.
However the convienience of this method comes at a price of accuracy. Thus intracellular water is mostly observed in the muscles bones and organs. Bia involves running a light electrical current through your body. Bia or bioelectrical impedance analysis is a non invasive measurement of body fat lean muscle mass and hydration. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat.
