The standard weight of men is: height (cm)- 105 = standard weight (kg).

The method of calculating the standard weight by the World Health Organization;

Male: (height cm-80) × 70% = standard weight.

Female: (height cm-70) × 60% = standard weight.

Standard weight plus or minus 10% is normal weight.

Standard weight plus or minus 10% ~ 20% overweight or underweight.

More than 20% of the standard weight is obese or underweight.

Extended data:

With the development of science and technology, the current body mass index value is only a reference value. To truly measure whether people are obese, we need to infer the thickness of fat by measuring the impedance of people with micro-electricity. Therefore, the role of body mass index has gradually changed, from medical use to mass weight loss index.

Adult body mass index numerical body mass index, male and female are underweight, below 20, below 19 moderate, 20-25, 19-24 overweight, 25-30,

24-29 obese, 30-35, 29-34 very obese, higher than 35, higher than 34.

Experts point out that the ideal body mass index is 22.

Because of the error, the body mass index can only be used as one of many standards to evaluate the individual's weight and health status. The National Institutes of Health (NIH) advises doctors to refer to the following three factors to assess whether a patient is overweight.

Body mass index waist circumference-measures the risk factors of abdominal fat and obesity-related diseases, such as hypertension, high LDL ("malignant") cholesterol, low HDL ("benign") cholesterol, hyperglycemia and smoking.

Because the body mass index does not take into account a person's fat ratio, a person with an overweight body mass index may not actually be obese.

For example, a person who practices fitness will have a body mass index of more than 30 because of his heavy muscle weight. If their body fat rate is low, they don't need to lose weight.
