Is it possible to lose calories from using your brain?

Question

It's from a scifi i read. is it possible to lose a noticable ammount of calories using your brain? (not that i'm fat and want to lose weight)

Answer 1

Yes, see the reference.

Answer 2

I believe so. The brain uses several processes etc etc, but if you are over working, like I am now, you will require more food energy to sustain yourself. Why do you think you lose weight when you stress over long periods of time etc. You wont lose weight in a noticeable amount, but over time you burn yourself out if you attempt to lose weight because you just won't be able to do it like that.

Answer 3

You won't use a 'noticable amount', but using your brain takes energy, and thus burns calories.
