Exercise is often touted as the cornerstone of weight loss, but it's not a cure-all. Here are three reasons why exercise alone might not lead to weight loss: First, intense workouts can make you sore and tired, which might reduce your overall physical activity throughout the rest of the day. This compensatory behavior can decrease the net calories burned, undermining exercise efforts. Second, exercise can significantly increase appetite. Without careful dietary management, the extra calories consumed can easily surpass those burned during a workout. Lastly, relying solely on exercise for weight loss can overlook the crucial role of a balanced diet, which is essential for effective and sustainable weight management.
