Calories burned by using your brain?

Just wondering if using your brain to do something mentally taxing burns more calories than just watching tv? Strikes me that it should but I have never read this anywhere- any ideas?

    Reading burns more calories than watching TV so I'd guess that mentally taxing tasks would burn even more than reading.

    I have heard running the brain burns 20% of our total energy usage but do not know if thinking burns more than not thinking.

    Apparently our brain is one of our most metabolically expensive organs, accounting for 20% of our resting metabolic calorie use. Unfortunately though, it seems that thinking hard doesn't change calorie uptake much, even though it might feel like it does!

    A nice article in Scientific American here: https://www.scientificamerican.com/article/thinking-hard-calories/

    Not enough to worry about. The silly little suckers sit there in our craniums revving themselves over every little perturbation of sight, smell, sound, taste, touch-sense, body orientation; plus operate and check on all the other body bits.

    They're busy every nanosecond, always, even when we're asleep. We just don't notice because we're not paying attention. (They're even busy creating that inattentive "we".)

    I think thermal constraints limit thought from chewing through too many calories.

    Well, it's not enough apparently for MFP to have that as a calorie burning exercise. But TV watching isn't either. And TV watching sometimes leads to mindless snacking, so there's that. Good question, though.

    Sure but your brain is constantly busy regulating all kinds of systems in your body. In computer terms you'd call it a bunch of always on background processes. Takes a lot of energy to run, just longer on your phone.

    This must be why when I study I get sooooooo hungry.

    I don't know. If I had a long taxing, thought filled day at work I know I'm exhausted....would be nice to think it was burning calories...but not betting on it

    When I drive the 800+ miles to Massachusetts I burn a lot. Yet it feels like I'm just sitting.
    The most inactive high burn rate activity I have ever done.

    Over a 10 year period. ;)
