I'm a grad student in the middle of finals, and my friends and I have been commenting that we think we get way more hungry and eat more during finals and were wondering if when you're really exerting your brain, you burn extra calories. Well, my friend just sent me this link that says when you're doing a crossword puzzle or similarly taxing your brain, you burn an extra 1.5 calories per minute! www.popsci.com/scitech/article/2006-07/men
I also then found this article that says that thinking uses up a lot of blood glucose as opposed to just lounging, which makes you THINK you need extra food, but in reality you've only burned marginally more calories. blog.nutritiondata.com/ndblog/2008/09/the-
On the other hand, your brain is a muscle and if you're working it extra hard it sort of makes sense that your body would burn extra calories to fuel it.
What do you guys think? Do you notice that you're more hungry if you're using your studying/doing something extra taxing at work?
