Interesting article in the American Journal of Lifestyle Medicine:
High-intensity exercise causes a short-term suppression of hunger of approximately 15 to 60 minutes. Although there is evidence for compensatory food consumption, it usually does not make up for the energy deficit created by exercise. The exception occurs when individuals consume or reward themselves with energy-dense foods or drink. Because people tend to eat the same volume of food each day, on days when they exercise, they will remain in an energy deficit. However, on sedentary days, a positive energy balance is likely if caloric restriction is not imposed, which could result in weight gain. Caloric restriction alone leads to loss of lean body mass, while the inclusion of exercise with an energy deficit helps conserve lean tissue.
