Different from women, obesity is mainly subcutaneous fat, and most of the fat that plagues men is concentrated in the abdomen. Therefore, in addition to being obese, obese men have a high proportion of medium height.

Extended data:

Measurement of perimeter and arc length of "three measurements";

Upper bust: The horizontal circumference passing through the left and right axillary posterior points (pap) when breathing calmly, measured with a soft ruler.

Bust III/bust III (m 61): The horizontal bust passing through the nipple point (th) during calm breathing, measured with a soft ruler. If the female subject's breasts are large or drooping, the soft ruler can be put higher when measuring to avoid the influence of breast swelling on the measured value.

Lower bust: The horizontal circumference of the chest passing through the lower bust point (sust) during calm breathing, measured with a soft ruler.

Waist circumference (M62): The circumference passing through the horizontal circumference of the navel center or the connecting line between the lowest point of the rib and the midpoint of the top edge of the iliac crest is measured with a soft ruler and measured before inhaling at the end of expiration.

Minimum waist circumference: the horizontal circumference of the thinnest part of the waist between the rib arch and the iliac crest. Measure before inhaling at the end of expiration, and measure with a soft ruler.

Abdominal circumference: the horizontal circumference of the abdomen passing through the iliac crest point (ic). Measure before inhaling at the end of expiration, and measure with a soft ruler.

Waist point circumference: the waist passes through the horizontal circumference of the left and right waist nodes and is measured with a soft ruler.

Hip circumference: the horizontal circumference of the most protruding part of the hip backward, measured with a soft ruler.
