In recent years, the global weight growth has far exceeded the global stock market growth. If the adult's body mass index (BMI) is considered overweight from the age of 25 and obese from the age of 30 (for a person with a height of 1.7 meters, that is, more than 73 kilograms is considered overweight and more than 87 kilograms is considered obese), then obese and overweight people in China actually account for one third, which is still in accordance with American standards. If according to Japanese standards, the body mass index is regarded as overweight from the age of 23 and obese from the age of 25-then at least half of the fat people, thanks to the kindness of the statistics department, have given people in the micro-fat world a way out!

There is a big problem with the body mass index (BMI), which is also considered "overweight". People with developed muscle groups and people with fat have great differences in body shape and body fat content. And thin people only have one figure, which is flesh and blood. There are two kinds of fat people: a pair of pear-shaped elephant legs and an apple-shaped belly that can squeeze into three times the sunshine.

Centripetal obesity, centripetal obesity, abdominal fat accumulation ... these confusing terms, in a word, are apple's big belly. What kind of belly is "big"? The simplest standard is waist circumference. The National Cholesterol Education Program (NCEP) of the United States considers that the waist circumference of men exceeds 102cm, or that of women exceeds 88cm, which is central obesity. However, the US Centers for Disease Control and Prevention believes that it is safe for men to have a waist-hip ratio less than 0.9, while a waist-hip ratio greater than 0.9 is a health warning. Some researchers have recently started to apply the Central Obesity Index (ICO), which is actually the ratio of waist circumference to height ... various parameters and so on. In fact, a person can't see his fingers with his head down, and how much he knows.
