Abstract
A body fat measuring apparatus for measuring body fat in a patient's body comprises apparatus for simultaneously measuring an impedance between the patient's feet, and for measuring the patient's height and the patient's weight, and a calculator for calculating body fat from the measured impedance value, height and weight. The calculator estimates body density using a formula having a correction term either for increasing the body density upon increase of the impedance compared to the original impedance or a correction term for decreasing the body density upon increase of the weight with respect to the original weight.
