Dieting is not helpful to lose weight in essence. You lose water, lean muscle and fat, but you gain fat again after gaining weight, so it's not worth the candle. Another serious side effect is that in order to seek the most basic energy balance, the body cells think that under the stimulation of repeated dieting, the body can not provide external energy normally and continuously, so it can only protect itself and try to reduce the internal basal metabolism level to achieve energy balance. At the same time, as long as you can replenish energy, you can hoard it to prevent it from being used again when you lose your energy source next time. Moreover, this metabolic abnormality will form a vicious circle of memory, so you will rebound if you eat less, and you will gain weight if you eat more. At the same time, it will increase the difficulty of losing weight every time you rebound. ? In addition, dieting needs to attract enough attention in terms of health hazards.

The problems that diet is easy to control mainly include the following points. ?

Anemia: the imbalance of nutrient intake makes the intake of hematopoietic substances such as iron, folic acid and vitamin B 12 insufficient; 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.

Uterine prolapse: Without adequate protection, the uterus tends to descend from the normal position along the vagina, the cervix sags, and even escapes from the vaginal opening, resulting in uterine prolapse. Severe cases may also lead to cervical infection and even cervicitis.

Gastroptosis: Women who lose weight through hunger often feel loss of appetite, flatulence and pain, which may be a sign of gastroptosis. People with obvious gastroptosis often feel abdominal discomfort, fullness and heavy weight, and their symptoms are aggravated when they stand after meals or are tired. When gastroptosis is serious, it is accompanied by visceral ptosis such as liver, kidney and colon. ?

Damage to brain cells: Physiologists believe that the result of dieting is a lack of nutrition in the body, which makes the damage to brain cells more serious and directly affects memory and intelligence. The longer you go on a diet, the more you lose weight and the greater your memory loss.

Hair loss: The main component of hair is a kind of protein called keratin, and zinc and iron are also indispensable trace elements for hair growth. Excessive dieting leads to insufficient intake of protein and trace elements, and severe malnutrition leads to hair loss. ?

Inducing gallstones: excessive dieting, due to the reduction of energy supply, leads to the consumption of fat deposited in tissues, and cholesterol moves out into bile, which makes the cholesterol concentration in bile surge, and bile becomes sticky and crystallized out. ?

Sudden death: Due to insufficient dietary calories and hunger, imbalance of copper, potassium, magnesium and other elements, plus sympathetic hyperactivity, myocardial cell atrophy, liver sugar deficiency, adrenaline can not be metabolized, so once stress occurs, it is easy to lead to arrhythmia, which in turn leads to cardiac paralysis and death.
