The fat-to-lean ratio of tissue on a human subject is measured by the subject standing on a platform (100), raising his or her heels, then allowing his or her weight to fall onto the board near a transducer to produce a force. A sensor transmits a voltage signal to an analog-to-digital (A/D) converter. The subject's stomach (300), buttocks (310), and other flesh will continue moving in a downward direction (335) (below their rest position) after the skeleton has stopped moving. This results in a downward force on the board which is registered as a data peak (580) in a computer through the action of the sensor and the A/D converter. Tissue elasticity will cause the stomach and buttocks to then move upward (350), above their normal resting position. This will result in a lessening of the force and a corresponding minimum (590) in the output wave. The wave thus is a damped sinusoid which can be analyzed using various means to result in an "excess pendulous fatty tissue index" which is indicated by humanly sensible readout display.
