The ideal value that is most conducive to health and longevity is 22, and the range of+10% conforms to the ideal range, which is the same for both men and women. Generally, young people use lower body mass index values, while old people use higher body mass index values. According to the value of body mass index and personal height, we can calculate the ideal weight of an individual.
Classification and standard of adult weight
Graded body mass index
Underweight body mass index < 18.5
The normal range is 18.5 ≤ body mass index < 24.
Overweight 24 ≤ Body Mass Index < 27
Mild obesity 27 ≤ body mass index < 30
Moderate obesity 30 ≤ body mass index < 35
Body mass index of severe obesity is ≥ 35.

Obesity is defined as excess body fat. Based on body weight, the normal body fat content of men is 12 ~ 20%, and that of women is 20 ~ 30%. The lowest body fat for maintaining health is 3% for men and 10 ~ 12% for women. Too low is not good for health, and women will have menopausal symptoms.
Because adults no longer grow, weight gain means fat gain, so high body mass index can represent obesity. According to the regulations of the Ministry of National Defense, the body posture of men in active service in China is body mass index >; 33 can be exempted from service; If athletes have developed muscles, they may also have a higher body mass index, but they are not necessarily obese.
Body mass index will also affect the length of life. Between the ages of 22 and 25, people with high or low body mass index will not live longer than those with body mass index, and they are more likely to get sick. Therefore, the importance of maintaining an ideal weight is generally evident. Body mass index will also affect the length of life. Between the ages of 22 and 25, people with high or low body mass index will not live longer than those with body mass index, and they are more likely to get sick.
