As classes get into full swing, your time is suddenly filled up with reading, late nights spent writing papers, and of course, eating. If you’ve been wondering why you’re always hungry when studying for History 210, researchers have an answer.

In a recent study done by Angelo Tremblay at his lab at the Universite Laval in Quebec, it was found that those performing mental tasks like trying to solve problems (e.g. Calculus 111), while working at a computer stimulated their appetite so much that they tended to eat more calories than their bodies actually burned while performing the task.

The psychological logic for the rise in appetite?  According to the study, mental work “destabilizes” our levels of insulin and glucose, which in turn stimulates the appetite.

Is this why after a weekend of total dedication to homework, I suddenly find I’ve depleted me and my roommate’s entire snack supply?

According to Tremblay’s study, participants consumed far more calories after performing a mental task like reading for a class than relaxing for the same amount of time. In addition, they concluded that time spent surfing the Internet, as well as instant messaging, may very well be a significant factor in the obesity epidemic amongst college students.
