Several commonly used judgment methods measure a person's fatness and thinness. The phenomenon in today's society is that both men, women and children will treat their bodies excessively with harsh eyes and take thinness as beauty. The following is my summary of the most commonly used judgment methods to measure a person's fat and thin.

1 1 and body mass index (BMI) are the most commonly used methods to measure a person's fatness and thinness. This is a widely used body shape judgment index in the medical field at present. Body mass index = weight (kg) divided by the square of height (m). For example, a woman with a height of 1.6m and a weight of 60kg has a body mass index of 601.61.6 = 23.4. This value is between 18.5 and 23.9, which is normal. If it is higher than 23.9, you need to lose weight; Anything below 18.5 belongs to emaciation, and nutrition should be strengthened. Note that body mass index does not reflect fat distribution. Some people have normal body mass index, but there is a lot of abdominal fat accumulation, and the risk of chronic diseases is high. Therefore, it is necessary to combine body mass index and waist circumference to judge whether to lose fat.

2. Ideal weight. The ideal weight is what people often say is the standard weight. There is no absolute standard for weight, so we call it ideal weight. Ideal weight (kg) = height (cm)-105. For an adult with a height 170 cm, the ideal weight is 65 kg. But this formula does not apply to children.

3. Waist circumference. Waist circumference can not only reflect the total amount of fat, but also reflect the distribution of fat, which is a good index to evaluate the risk of chronic diseases. Adult male waist circumference should be less than 85 cm, female waist circumference should be less than 80 cm. Measure the waist circumference and stand with your feet 30 cm apart, so that your weight will be evenly distributed. The measuring part should be flat on the navel, and close to the skin with a soft ruler, but not pressed.

4, waist-hip ratio example. That is, the ratio of waist circumference to hip circumference is less than 0.9 for men and less than 0.8 for women.

5, subcutaneous fat thickness. The subcutaneous fat thickness of abdominal wall should be less than 15 mm in men and less than 20 mm in women. This usually requires a professional sebum thickness gauge to measure.

Losing weight needs to be gradual. Generally, it is safer to lose 0.5 kg per week, and it is easy to accept and adhere to. If you lose weight too fast, it may cause weakness, hair loss, depression, arrhythmia and other problems. In addition, due to the rapid decomposition of fat, it will lead to the increase of ketone bodies in blood, which will cause acidosis and serious consequences. Therefore, weight loss should be carried out in a planned way. Weight control should become a life philosophy and persist for life. Dieting and moderate exercise are the healthiest ways to lose weight. If there are no special circumstances or diseases, it is not recommended to use drugs, surgery and other methods.

Several common judgment methods to measure a person's fat and thin II. What is the reason for deciding to be fat or thin?

1, some people are not fat when they eat, while others are fat when they drink water?

The truth of deciding whether to eat fat or thin:

After food enters the human body, it focuses on absorption and metabolism. The same food, entering different human bodies, causes the difference of body shape, which is also composed of these two links. In other words, regardless of genetic factors, it is your absorption and metabolic function that determines whether you are fat or thin.

absorb

When food enters the digestive tract, it will first be decomposed into various nutrients, absorbed by the human body through the intestinal wall and stomach wall, and finally enter the human body and become a part of the human body. People with weak gastrointestinal function, the digestive system can not function normally, and the food is excreted before digestion, so it is naturally difficult for the human body to absorb nutrients. The weight of this kind of human body will not increase, but there will be problems of weak constitution and low immunity.

To metabolize.

Metabolism is burning calories. People's physique is influenced by genes. Some people are born with strong energy metabolism. Even if they lie still in bed, they consume more energy than the average person. A lot of exercise can also achieve the goal of high metabolism. In addition, it is worth mentioning that when the human body is underage, if you exercise more, it will improve the body's basic metabolism and benefit for life.

We see that people who are not fat no matter how they eat generally have strong absorption and metabolism functions. Their stomach bags are relatively strong, and the absorption and metabolism ability of the stomach digestive system is particularly developed.

But if you are a big eater without special constitution, be careful. Loss of glucose and disorder of insulin secretion will increase food intake, which may be a symptom of diabetes; It is easy to get hungry after a meal, indicating that the metabolism is too strong, which may be caused by too much thyroid hormone.

How do ordinary people eat?

If ordinary people want to eat more and not be fat, besides increasing exercise to improve body consumption, they can also avoid obesity by paying attention to food calories and reducing calorie intake. For example, vegetables and fruits have relatively low calories, while cakes, pizzas and ice creams have high calories. You can eat more fruits and vegetables and less sweets. Boiled vegetables have lower calories than fried vegetables; When buying finished food, you can pay attention to the food ingredient list, pay attention to the food calories, and try to choose foods with lower calories to eat. ...
