-First of all, you must have a big breakfast.

This is very important, you must remember it.

First of all. At lunch, drink a glass of water first, then chew slowly.

Second. When eating, don't eat, eat cucumbers. If you feel that cucumbers are not full, you can eat whole wheat bread first, but you should chew slowly. Never eat after 8 o'clock.

If you are hungry a few hours after a meal, drink water and boiled water.

Third, don't sit down after dinner. Get up and walk for about 15 minutes.
