Exercise alone is not typically enough to lose weight effectively. While physical activity is crucial for burning calories and improving overall health, weight loss is primarily driven by a combination of exercise and a healthy, balanced diet. To lose weight, you need to create a calorie deficit, meaning you burn more calories than you consume. Exercise helps increase the number of calories burned, but if you continue to eat more calories than needed, weight loss will be limited. A well-rounded approach, including portion control, nutrient-dense foods, regular exercise, and proper sleep, is key for sustainable weight loss.
