Food cravings are a common phenomenon that can occur in anyone, and sometimes affect the process of maintaining a certain diet.

Cravings for sugar and unhealthy foods are a big problem if they occur too often, because of the long-term health consequences they cause.

Hunger is your body's natural signal that you're hungry. When you're hungry, your stomach may make noises and feel hungry, you may have cravings, or you may have a headache, feel irritable, or be unable to concentrate.
