Silly question

Does thinking hard burn calories?

I took a $250 IQ test a couple weeks ago, and it was an hour and a half long. After the test, my head hurt and my whole body felt weary just as if I had gone for a 30 minute jog.

I know that the brain is the most energy-consuming part of the body, could we be overlooking it as a form of metabolic raiser(calorie consumer), or am I just retarded?

All organisms needs energy, so do your brains.

It generates a powerful electrical field and uses a lot of energy, kind of like any processor.

I often substitute thinking hard for jogging while I'm cutting.

As far as I know, that's most likely due to a stressing lifestyle rather than some supposed calories' expenditure by the brain...

Brain uses about 100g of glucose a day, which is 400 calories. The more you use your brain the more glucose it'll need so the more calories it consumes.
