This is not recommended. Generally speaking, a simple diet can make you lose weight in a certain period of time, but it doesn't mean losing weight. In the long run, improper dieting has no obvious weight loss effect.

First, the human body needs calories every day to maintain its basic metabolism. If it only eats a little food, it needs to "use its body reserve", but this reserve is not all fat, and the proportion of muscle loss is far greater than the proportion of fat consumption, so the weight loss effect is not good.

Second, improving basal metabolic rate is an important way to lose weight effectively. Simply dieting directly leads to the decrease of basal metabolic rate, that is, the body will adjust itself, which will reduce the calorie consumption in daily life (many people will be too lazy to move and have no strength), and then the fat consumption will be even lower than when they don't diet.

Third, being hungry for a long time will "remind" the body to store more energy, and the most economical energy reserve is precisely the accumulation of fat. Therefore, this kind of diet plan is very likely to rebound in weight, and it is easy to form the problem that "drinking cold water will make you fat".

Fourth, excessive dieting will affect the normal operation of the endocrine system. Endocrine disorders often become the cause of further imbalance of body fat ratio.

Therefore, it is ok to control your diet, but you can't worry. You have to calculate your calorie intake and consumption level, which is lower than the consumption level. The average person has no special circumstances, so it is best to ensure the daily intake of 1200 calories. At the same time, aerobic exercise is still the most practical and simple way to increase fat consumption.
