It is not advisable to lose weight quickly. Fast weight loss is at the expense of health, which is naturally difficult to sustain, while reasonable weight loss is based on ensuring good health, so it is slow but lasting.

In fact, it is very easy to lose weight quickly. Eating less and exercising more will be significantly reduced in a short time. However, eating less and exercising more does not consume fat, but protein. When you eat too little and your body is short of sugar, your body will break down protein to provide energy instead of consuming fat. If this state lasts for a long time, the body will enter a state of low energy consumption, but it will be more difficult to consume fat. But in this process, the weight will indeed continue to decline, and there is no pressure to lose 20 pounds a month.

However, this is caused by malnutrition, and losing weight at the expense of health will only have two results in the end. First, because of the decline in health, I couldn't stand it and began to return to normal diet. However, because the body has entered a state of low energy consumption, the original normal food consumption can not be consumed, and it will be more converted into fat, so the weight will rebound quickly. The second is bulimia or anorexia caused by excessive dieting. This will be a big problem. The former will lead to a surge in weight, while the latter is very dangerous and can cause death in severe cases. Therefore, the result of fast weight loss must be that after a period of time, dieters can't bear it because of their declining health, lose weight quickly and rebound quickly.

Healthy weight loss is bound to be slow but sustainable. Generally speaking, the limit of healthy weight loss is to lose about 8% of the original weight every four weeks. This is the result of experiments conducted by sports physiology research institutions all over the world for all ages and races in the past 30 years. The result of healthy weight loss is that it can be reduced continuously, without stress and without affecting health. Every month, you can guarantee to lose 4% to 5% of the weight at the beginning of the month, and it will be a considerable number in a few months. The so-called fast weight loss will generally rebound in the second month. So don't be superstitious about losing weight quickly, you must rely on dieting to achieve it. The result is unsustainable and will definitely rebound.

Losing weight depends on time, and you can't rush for success. After all, you haven't gained weight in a month. Why do you want to lose weight in a month?
