Craving refers to an intense desire to consume a substance. Food craving refers to an intense desire to consume a particular food. It is this specificity that differentiates food cravings from feelings of hunger. A craving for a specific food can only typically be satisfied by consumption of that food – while hunger can be alleviated by consumption of any type of food. Moreover, food cravings can occur in the absence of hunger – food deprivation is not a necessary condition for the occurrence of food cravings.
