If we hit the gym, don't we deserve a little extra something, maybe something sinfully sweet? The idea that sacrifice begets reward is embedded in our collective thinking.
But a fascinating new study from the folks at the Cornell Food and Brand Lab shows how this thinking might backfire. Thinking of exercise as work can lure us into mindlessly devouring calorie bombs, such as a big helping of pudding or extra handfuls of M&M's. And compensating for physical activity with sweet treats this way may lead to weight gain.
