As you eat, your body releases leptin, which signals that you're satisfied and don't need to be hungry for a while. In other words, your body needs food, so it produces ghrelin. That makes you hungry, so you eat. Then, your body doesn't need more food, so it produces leptin. That makes you feel full, so you stop eating. But that chemical balancing act can be thrown out of whack if you ignore your hunger signals and don't eat regularly.
Go long enough without eating, and your body will try to coax you into eating by producing more ghrelin. And in most people, most of the time, that's exactly what they do. But not always.
