This method is based on the measurement of body impedence where a safe low high frequency alternating current is sent around the respective areas of the body and calculates the resulting drop in voltage and the displacement of phase between current and voltage. Information regarding the distribution between the virtually non-conductive fat and good conductive body substances (water, blood, muscles, bones) can be gained from both these readings. Different areas of the body can be measured using different electrode arrangements (foot – foot, hand – hand, right foot – left hand etc.).
