Drink three more days. Drink water when you are hungry.

No snacks, not at all. But it will make you feel that living is not fun.

Eat less, and you won't have to eat dinner. Eat less every time, and eating less and eating more meals is nonsense. Eating less will make you thinner.

Drink soup if you can, but don't eat when you are full. You can eat more watermelons in this weather.
