I just want to ask, where exactly did you measure your waist?

Waist circumference should be measured at the waist passing through umbilical point. The measurement method is as follows: when measuring the waist circumference, stick the soft ruler on the skin, draw a circle 3cm above the belly button, and then read it. Please refer to the figure below.

Waist circumference (WC) refers to the horizontal circumference of the waist passing through the umbilical point (om), which is a comprehensive index reflecting the total amount and distribution of fat. The measurement method recommended by the World Health Organization is that the subjects stand with their feet 25 to 30 cm apart and their weight is evenly distributed.
