If you don't eat breakfast, you will easily get gallstones. Breakfast is the most important of the three meals. The nutrients and calories it provides should account for 1/3 of the whole day intake. You gave up, and at the same time you gave up lunch, which is even more undesirable.

In addition, to lose weight, it is important to insist on aerobic exercise every day-jogging, swimming, brisk walking, playing ball games and so on. However, please pay attention, but-every aerobic exercise must last for more than 40 minutes to lose weight, because sugar (glycogen stored in the liver) is basically consumed in the first 30 minutes of every aerobic exercise. After more than 40 minutes of continuous exercise, the body will start to burn a lot of fat (because there is not enough sugar in the body, fat needs to be converted into sugar to continue to provide the energy needed for exercise). Therefore, if you exercise continuously for half an hour every day, there is basically no weight loss effect, just consuming your liver glycogen, and the fat can't be reduced. In addition, glycogen depends on food such as starch, and if you don't eat it, you will easily get hypoglycemia+severe organ decline+decreased resistance. In the long run, you will get old early, be tortured by diseases, affect your mood, and be irritable or depressed.

This is a stupid idea!
