Standard weight is one of the important signs to reflect and measure a person's health. Being too fat and too thin is not good for your health, nor will it give you a sense of bodybuilding. A large number of statistical data of different body types show that the ideal and simple index reflecting normal weight can be expressed by the relationship between height and weight.
Second, the judgment criteria
Body Mass Index (in English) is a number obtained by dividing the weight in kilograms by the square of the height in meters, and it is a commonly used international standard to measure the degree of obesity and health. When we need to compare and analyze the influence of a person's weight on the health of people of different heights, the body mass index is a neutral and reliable indicator.
Third, not everyone applies the body mass index, such as:
1.1under 8 years old;
2. As an athlete;
3. I am doing weight training;
4. Pregnancy or breastfeeding;
5. frail or sedentary elderly people.
If you think that the calculated results of body mass index can't correctly reflect the weight problem, please discuss with your doctor with the results and ask for a body fat test.
Extended data:
If your weight exceeds the standard value 10% ~ 20%, you will live longer.
1, Professor stiles, an American gerontologist, found that among people over 70 years old in California, if they exceed the standard weight 10% ~ 20%, the mortality rate is the lowest. When the weight is too low or too high to 30%, it is easy to cause diseases and affect life expectancy.
2. The reason why fat people live long is that the subcutaneous fat layer of fat people is thicker, and their cold resistance and disease resistance are stronger than those of ordinary people, and they can withstand the "torture" of diseases. However, thin people have relatively weak resistance and poor adaptability to the environment, especially acute infectious diseases such as influenza, upper respiratory tract infection and pneumonia, so they are sick and short-lived.
3. Medical research also found that if women lose weight obviously from the age of 50, they are prone to fractures, especially hip fractures. In addition, the incidence of visceral ptosis in thin people is very high, and the most obvious is gastroptosis. Therefore, when people get old, they should not be too fat, but they should not be too thin, and it is better to be a little fat. Of course, exercise and mental health are also important.
