1. A method for determining percent fat in a body, comprising:

  • (a) providing a near-infrared quantitative instrument comprising(i) at least one point source of near-infrared radiation;

    (ii) a near-infrared radiation detector capable of providing an electrical signal upon detection of near-infrared radiation;

    (iii) means for preventing near-infrared radiation from said at least one point source from impinging directly on said detector;

    (iv) locating means for placing said at least one point source against a body to be tested so as to introduce near-infrared radiation into said body, wherein said locating means positions said detector for receiving near-infrared radiation from said at least one point source that interacts with said body and for providing an electrical signal corresponding to the fat content of said body; and

    (v) means for converting the electrical signal corresponding to the fat content of the body into a readout indicative of the percent fat of the body;

    (b) placing the at least one point source against a body to be tested with the detector or positioned for receiving near-infrared radiation that interacts with said body;

    (c) transmitting near-infrared radiation into said body;

    (d) detecting near-infrared radiation which interacted with said body; and

    (e) providing a readout of percent body fat corresponding to an electrical signal indicative of near-infrared absorption provided by said detector.
