Body mass index was originally designed as a statistical tool for public health research. When we need to know whether obesity is the cause of the disease, we can convert the patient's height and weight into body mass index, and then find out whether there is a linear correlation between this value and the incidence. However, with the development of science and technology, the current body mass index value is only a reference value. In order to truly measure whether a patient is obese, it is necessary to measure the patient's impedance by micro-electricity, so as to infer the patient's fat thickness. Therefore, the role of body mass index has gradually changed, from medical use to mass weight loss index.

Adult body mass index value:

Too light: less than 18.5

Normal: 18.5-23.9

Overweight: 24-27 years old

Obesity: 28-32 years old

Very obese, over 32 years old.

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.

Body mass index waist circumference measures abdominal fat. Risk factors of obesity-related diseases, such as hypertension, low density lipoprotein (? Malignant? ) high cholesterol, HDL (? Benign? ) Low cholesterol, high blood sugar, 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.

1, what is the use of body mass index?

Everyone's physical examination first measures their height and weight. Therefore, the body mass index is the simplest method, which is suitable for all ages and can be tested at home. Body mass index = weight (kg)/height (m) x height (m). So through simple calculation, you can know whether your weight is normal or not.

2. How good is a woman's body mass index?

It is generally believed that women's body mass index is 18.5-24, which is normal. But it just means that the body mass index is not perfect. Because the body mass index is just a general formula. He spoke from the overall situation of his body.

Such as women of the same height and weight. Their bodies are different. There are apple-shaped bodies, pear shape, elephant legs, paunch and so on. Therefore, besides body mass index, we should also consider other factors. Here are some important things to talk about.

3. What should I pay attention to besides body mass index?

In addition to body mass index, there are several main physical indicators:

(1) subcutaneous fat

In life, everyone has reached the standard, and people without stomachs have mild or moderate fatty liver. This is the reason for subcutaneous fat, so besides body mass index. Also pay attention to subcutaneous fat.

(2) Abdominal fat

Some women have a normal body mass index, but they have a lower abdomen and even a big belly. This kind should also pay special attention. Because abdominal obesity has a certain relationship with hypertension, hyperlipidemia and aesthetics, we should also pay attention to this. It is generally recommended to be below 80CM, but it needs to be evaluated by professionals.

(3) Chronic diseases:

If you have hypertension, hyperlipidemia, hyperglycemia, or other chronic diseases, you need to maintain your weight according to the advice of clinicians or your own diseases, rather than simply referring to the body mass index.

Generally speaking, body mass index is an important parameter to evaluate weight and health. But it is better to add some physical parameters according to your own specific situation.
