[General Fantasy] How many calories must a giant consume on a daily basis?

And what do they eat?
gpt
Let's say they're x times taller than a human. Their weight would go up by a factor of x^(3). It would take them √x times as long to fall a proportional distance, and since walking is a controlled fall each step would take √x times as long, but it would take them x times further so they'd actually move √x times faster. Since they move x^3 times the force across √x times the distance, they end up using x^3.5 times as much energy.

So, for example, if a six foot man eats 2000 calories a day, then a 24 foot man would eat 4^3.5 = 128 times as much, or 256,000 calories per day.

Different giants eat different things. Snozzcumbers are one option.

That said, all this is based on the assumption that they're built and they move like regular humans but a little slower. Given the square-cube law and the caloric requirements, this isn't likely.
