Using Brain is Consuming More Calories Than Exercising?

I am eating the 8th meal today.
I study a bunch. That is why?

Suggestion:

There is a certain amount that is used everyday by the entire body regardless of what you do. Extra goes into exercising or gets turned to fat possibly if you don't use it. Studying doesn't really change the amount of calories the brain uses. However, keeping a fast metabolism will burn calories without doing much and one of the ways you keep a fast metabolism is to eat lots of little meals. The reason for this is when you let yourself go long periods without food, the body thinks there is no food around and slows its metabolism to keep you going longer.
