An hour of running may actually suppress junk-food cravings, says a study out of Scotland’s University of Aberdeen. After running on a treadmill for 60 minutes, volunteers viewed images of high- and low-calorie fare. MRI scans then showed that “following exercise, parts of the brain that control appetite began to ‘light up’ when viewing low-calorie foods”—meaning, the brain considered them rewarding—“but the rewarding aspect of high-calorie foods was suppressed,” says Daniel R. Crabtree, Ph.D., who led the research. “There was also a reduction in feelings of hunger and a desire to eat, and an increase in fullness.”
