Under normal circumstances, the standard weight of a man should be the height minus 105, that is to say, the male friend of 178cm should be kept at 73 kg, so that the fluctuation of his weight will generally not exceed 10%. In other words, if your height is 178cm, then you can't be thin above 65 kg, and you can't be obese below 80 kg. But if it is not within this range, we should pay attention to controlling our weight, because it is not good for our health whether we are too thin or too fat.

If you are too thin, your body will lose hair more easily in the first place. Because people who are too thin lack protein and fat, it is difficult to have extra nutrients for their hair, and they are more prone to hair problems such as dryness and dullness, and they are more likely to lose a lot of hair when combing their hair. This phenomenon also appears in people who are over-dieting, mainly because the scalp can't get enough nutrition, especially iron.

Secondly, it is easy to osteoporosis. The thin man himself looks very fragile, as if he would break when pushed. Indeed, because there is no muscle protection, bones and joints will be more vulnerable to injury. Coupled with the lack of nutrition, the hormone level in the body is too low, which leads to problems in calcium absorption, and a large amount of calcium will be lost, so it will be more prone to osteoporosis.

Then there is memory loss and anemia. Thin people's brains don't have more nutrition supply, so they will run slower than others, and if they do this for a long time, their brain cells will be damaged, so their memory will get worse and worse. The emergence of anemia is mainly due to the lack of vitamin B 12, iron and other nutrients in the body; There is also slow gastrointestinal peristalsis, which leads to failure to absorb nutrients in time, leading to anemia.

If you are too fat, the knee joint will suffer first, because the weight of the whole upper body is pressed on the knee joint, plus more fat and less muscle strength, and the knee joint is prone to problems, leading to serious wear and tear, so if you are fat to a certain extent, it is a problem to finally stand up.

Secondly, some chronic diseases are easy to target themselves. Because obesity is caused by too much fat, it is easy to cause hyperlipidemia, so it is easier to form blood clots and blood vessels will lose their elasticity. At this time, chronic diseases such as hypertension and hyperlipidemia will break out, which may be caused by poor control. Myocardial infarction.
