ELI5: why have humans evolved to only be required to consume such a small percentage of their body weight daily relative to some other animals on earth?

We tend to eat relatively high-calorie diets, with our focus on grains and other carbohydrates. We also cook our food, which makes it easier to get at the calories. By comparison, a lot of plant-eaters have to chew, swallow, partially digest, regurgitate, and re-chew their food to get the maximum out of it, nutritionally. Another way of doing the same thing is to just eat a huge amount of food, and process it quickly.
