Most of the time it is not about real, physical hunger, but rather it is our mind that is playing tricks on us.
Drink a large glass of water straight away. Distract yourself. Read something, go for a walk or watch an exciting movie.
Hunger comes in waves, and after a short time it subsides again. Perseverance is the motto!
Make sure to eat healthy foods during meal times and limit your sugar intake. This also prevents food cravings.
