And normal people usually have lunch from noon 12 to afternoon 1. If they don't eat at night and eat again the next morning at around 7 or 8 o'clock, then we should have an empty stomach for at least ten hours. At this stage, we will consume fat after digesting our calories, so it has a certain effect on losing weight.
However, this method of losing weight is generally not recommended, because it is really harmful to our health, especially to the stomach and intestines, and it is easy to cause some diseases. Moreover, although this method of losing weight is very effective, it will rebound once the normal diet is restored, and even obesity is more serious than before, and skipping dinner will affect the quality of sleep and mental state. So I suggest you don't try, just exercise honestly and eat less. Ah, by the way, don't eat too greasy food, or you will try to lose weight for many days and go back to before liberation.
