Water can support the space in your stomach, reduce hunger and slow down the urge to eat. Tighten your belt and move your limbs. Tightening the belt can increase the pressure on the abdomen and reduce the space in the stomach. If you cooperate with the transfer of attention, you can effectively reduce your appetite.

Eat some fruit or sugar before meals. A study by St. George's Medical College in London, England, found that one group of people ate some glucose before meals, while the other group ate normally.
