Bioelectrical resistance is used to predict body fat. This is done by sending a small electrical current through the body and then looking at the change in current when it comes out of the other end. The person completing the test should not be touching any other non conducting surface. Fat free mass within the body is mostly made of water, which is less resistant compared to high fat mass. Taking this into account you can use the current which comes out of the body after travelling through to predict how much fat there is in your body.
