The Weight Loss Equation
Weight loss fundamentally requires burning more calories than consumed. While diet plays the primary role in initial weight loss, exercise is crucial for long-term weight maintenance.
CDC research confirms that combining calorie reduction with regular physical activity provides the most effective and sustainable weight loss results.
