Eating and drinking is absolutely impossible.

Don't eat one day, eat a lot the next day. This will absorb more than your whole day's meal. So try to control your appetite.

Eat all three meals, depending on what you eat ... it's better to eat vegetables cooked in water than starve yourself. Eat more and exercise more so that you won't get fat.

Try mustard powder and green tea powder. Add a cup of warm water. Drinking it is very effective for losing weight.
