Appetite: A desire (longing, craving) for food or drink. Having motivation to consume a food or drink that contains calories.
Americans, as a rule, are in bondage to their persistent appetites for “problem foods”. In fact, the typical American appetite is more foe than friend. Just look around to see the evidence. Americans love to eat! And the food industry capitalizes on this human weakness by offering us sweet and savory delights that are literally devastating to our health.
