Yes, physical activity increases total energy expenditure and thus burns more calories than being sedentary. The more intense the activity, the higher the number of calories burned. However, even light activities, such as standing, walking, or household chores, can contribute to daily caloric burn.
Regular physical activity also has metabolic benefits beyond immediate caloric expenditure. It can enhance muscle mass, which burns more calories at rest than fat does, leading to an increased basal metabolic rate. It can also improve metabolic flexibility, or the ability to switch between burning carbohydrates and fats for energy, which is associated with improved metabolic health.
