Abstract

The present invention relates to a method and an apparatus for measuring a distribution of body fat for human body. The method comprises the step of measuring a bioelectrical impedance and a thickness of abdominal subcutaneous fat, based on the personal data such as sex, age, height, weight, etc. The method further comprises the step of calculating an area or an amount of abdominal visceral fat or abdominal subcutaneous fat, based on the measurements of the bioelectrical impedance and the thickness of abdominal subcutaneous fat as well as the girth of abdomen. According to another embodiment of the present invention, the method comprises the step of measuring the thickness of abdominal subcutaneous fat and the girth of abdomen. Thereafter, the area of abdominal visceral fat and the area of abdominal subcutaneous fat are calculated, based upon the measurements of the thickness of abdominal subcutaneous fat and the girth of abdomen.
