However, by the middle of the afternoon, you are very uncomfortable with the empty feeling in your stomach and feel you "have to eat." This is caused by psychological hunger that incites you to eat.
Psychological hunger is caused by the desire to eat our of habit, you see something "yummy" or you are in the mood more food. So if you are on a diet, it is very important to know the difference between psychological hunger and real physical hunger. If you feel an emptiness in your stomach, is physical hunger. If you just want to eat and do not feel the emptiness and the rumbling in your stomach, then is psychological hunger. Refrain from this.
