The Science of Hobbit Gluttony

In Tolkien's world, Hobbits are small yet eat frequently due to their energy needs. Kleiber's Law helps explain this by stating that an animal's energy requirement scales with the three-quarter power of its mass. This means smaller animals need more food relative to their size than larger ones. The relationship between surface area and volume also plays a role, as larger animals lose heat more slowly. Applying these principles, Bilbo Baggins, a Hobbit, would need to eat more frequently than a human to meet his energy needs.
