As the saying goes: old and thin, people live long! That is to say, when people get old, it may be easier to live longer if they are thinner, because they can get rid of all kinds of obesity complications and move more flexibly, but there are different types of thinness, which are mainly divided into healthy thinness and unhealthy thinness. Among them, healthy thinness refers to the normal activities of various organs of the body, which can ensure the daily intake of nutrients, but because of more exercise or normal metabolic function of the body, they are thinner. Unhealthy thinness refers to low interest in food because of uncoordinated body parts, so thinness is not a sign of longevity due to malnutrition.

People are old, can you be a little fatter?

As we all know, a large amount of fat will accumulate on the body surface of obese people and even squeeze into organs and blood vessels of the whole body, which will not only increase the operating burden of organs, but also hinder blood circulation. These are the adverse effects brought by obesity, but fat is not without its merits. First of all, it can help the body keep warm against the cold, especially in winter, and there are few abnormalities caused by freezing. Fat also has a certain buffering effect. But there is a limit to being fat. If you are too fat, it will still become a burden on your health, so there is no direct relationship between obesity and longevity.

Old people who really live long weigh in this number.

From the above analysis, we find that both being fat and being thin have certain advantages, but they also have certain disadvantages. Therefore, we investigated the weight of the long-lived elderly, and found that if the height of 170 cm is taken as an example, it is normal if the weight can be kept within 55 kg to 70 kg, that is, the value of height cm divided by weight kg is between 2.5 and 3, which is considered to be a relatively healthy weight and is more easily liked by the long-lived people because of this number.

Nutritionist's point of view: In fact, there are many factors that determine longevity, and each factor has a certain relationship. For example, weight is related to the usual eating habits and exercise habits. To ensure a healthy weight, we must pay attention to diet, control food intake, and keep exercising. Only by doing everything well can longevity notice you.
