Abstract
Method and apparatus for determining percent fat in a body wherein substantially uniformly dispersed near-infrared radiation is transmitted into the body to achieve optical interactance between the body and the near-infrared radiation. Optical absorption by the body at only one wavelength of the near-infrared radiation is measured. The measured absorption at the one wavelength of near-infrared radiation is utilized to quantitatively determine the fat content of the body. Data on a plurality of physical parameters of the body, such as height, weight, exercise level, sex, race, waste-to-hip measurement and arm circumference, can be utilized along with the measured near-infrared absorption in the quantitative determination of body fat content.
