Because being too thin will cause many physical and psychological problems, which is what people around you talk about. Ask yourself, is it beautiful to be thin? Or is it because we keep saying that, so we think so?

First of all, aesthetics is very easily influenced. Aesthetics is easily influenced by culture. For example, many people in China say that they can only appreciate the beauty of China people, but they can't appreciate blond hair and blue eyes. It is because I usually see Asian faces that I am more sensitive to Asian faces. People with blond hair and blue eyes look the same.

The danger of being too thin

1 and anemia

Too thin people generally have the problem of unbalanced nutrient intake, and iron, folic acid, vitamin B 12 and other hematopoietic substances are insufficient. Because of eating less, the basal metabolic rate is lower than that of ordinary people, so the gastrointestinal movement is slow and the gastric acid secretion is less, which affects the absorption of nutrients. These are the main causes of anemia. In addition, malnutrition reduces the body's immunity and is prone to secondary anemia.

2. Memory loss

The main motivation for brain work comes from fat, which can stimulate the brain, accelerate the brain's ability to process information and enhance short-term and long-term memory. The thin human body is short of fat intake and storage, and the body is short of nutrition, which seriously damages brain cells and directly affects memory, so we become more and more forgetful.

3, hair loss

The main components of human hair are protein called fish protein and trace elements such as zinc, iron and copper. Too thin people have insufficient supply of body fat and protein, so their hair frequently falls off and their hair color gradually loses its luster.
