Because smaller animals have to eat more relative to their bodyweight, Tolkein’s hobbits need to eat a lot - not for comfort, but for survival.

To learn more about this topic, start your googling with these keywords:
Metabolism: The chemical processes that occur within a living organism in order to maintain life.
Square-cube Law: A mathematical principle which describes the relationship between the volume and the surface area as a shape's size increases or decreases.
Kleiber’s Law: The observation that, for the vast majority of animals, an animal's metabolic rate scales to the 3⁄4 power of the animal's mass.
Calorie: Unit of energy. One food calorie equals 1 kilocalorie.
