A: Overeat

Overworking your brain may cause overeating. The stress of thinking drove folks into feeding frenzies, says a study reported in the journal, Psychosomatic Medicine. Researchers compared the hunger drives of students who performed three tasks sitting and relaxing, reading and summarizing text and taking a complex computer test. After each task, the scholars were unleashed on a buffet. Compared to the resters, the readers wolfed down 203 more calories, a 23.6% increase, and the computer gamers gobbled 253 more calories, a 29.4% increase. “Overeating after intellectual work could contribute to the obesity epidemic,” says study leader Jean Philippe Chaput of Canada’s Universite Laval. “We can’t ignore this factor because more and more people hold jobs of an intellectual nature.”
