Because, in the short term, dieting to lose weight may cause weight loss, but it is only a temporary "illusion" and will soon rebound after returning to normal diet. Moreover, long-term intake of too few calories and insufficient energy supply will cause a series of adverse reactions, which will not only make you slim down, but also endanger your health.

2. In the late stage of dieting, muscle loss is serious.

When you go on a diet for a period of time, the glycogen stored in your body is basically exhausted, so your body will consume fat and muscle sugar for energy. Over time, although you can lose some fat, it also causes the loss of muscle, which will lead to the decrease of basal metabolism, which is even more unfavorable for weight loss and aggravates the possibility of rebound.

3 malnutrition, hindering fat metabolism

The body needs to take in enough nutrients to maintain normal metabolism, including fat metabolism. For example, calcium can combine with fat in food in the intestine, block the absorption of fat in the intestine, and let fat be excreted with feces. In addition, B vitamins are also important substances involved in fat metabolism.

4 The body opens the self-protection mechanism, and the calorie intake is reduced.

When the calorie intake is seriously insufficient for a long time, the human body will start a self-protection mechanism to maintain normal operation by reducing calorie consumption, resulting in a decrease in your daily calorie intake. So even if you reduce your calorie intake by dieting, it is easy to lose weight.
