HIIT Reduces Food Intake
Exercise usually increases appetite and food intake. That’s not true of high-intensity interval training (HIIT). A study on obese men from the University of Western Australia showed that HIIT reduced post-exercise food intake for 38 hours compared to a moderate-intensity (60 percent of maximum effort) workout. Following HIIT, test subjects had lower levels of ghrelin, a gut hormone that increases appetite. The men tolerated HIIT well. This type of training might be appropriate for people with limited time for exercise or those who want the workouts to end sooner. However, HIIT is not for everyone because it is extremely strenuous.
