A visceral fat area estimating system of the present invention comprises first
input unit for inputting a height of an subject, second input unit for inputting
a body weight of the subject, third input unit for inputting a fat mass of the
subject, fourth input unit for inputting age of the subject, computation unit for
computing a visceral fat area based on data from the first, second, third and fourth
input unit, and display unit for displaying the visceral fat area computed by the
computation unit. Therefore, the system can estimate a visceral fat area securely
without concern for exposure of an subject to X-rays, at low costs, and with proper accuracy.
