hunger can also be very misleading. I've found that being thirsty, angry, or just plain bored can often make me think i'm hungry. Sometimes just getting up and going for a walk or drinking a big glass of water and all of a sudden i'm not hungry anymore.
Totally, I bet 90% of the time hunger is confused with thirst, I think the mechanisms that regulate hunger and thirst are very close in the brain. Every time you feel like eating something like bread, maybe it's because your las food was salty and spicy, so you're thirsty.
And yes, if you are bored, going to the refrigerator can be a "busyness", and definitely if you are tired and angry, food can serve as a relief.
