It’s really possible to sweat out your appetite. Doing several rounds of intense intervals might make you eat less, reports new Australian research.
In the study, researchers found that men who completed an intense sprint session consumed fewer calories over the ensuing 38 hours than those who completed a continuous workout at moderate intensity. “Intense exercise may suppress ghrelin, a hunger-stimulating hormone,” says Aaron Sim, Ph.D., lead author of the study.
Working out may also train your brain to eat cleaner. In a new study published in Neuroreport, when active healthy people looked at pictures of junk food, the brain regions associated with appetite were less stimulated than those of more sedentary people. In other words, physical exercise may be associated with reduced activation of the food responsive reward regions, which are in turn associated with reduced preferences for unhealthy high calorie foods. According to the researchers, exercise increases sensitivity to the appetite regulating hormone leptin, which may lower the appeal of high calorie foods.
So, exercising regularly not only keeps you fit, but also can improve your eating habits!
