Obesity is now considered an epidemic and is a leading cause of preventable death in the US. Losing weight can improve health and quality of life by reducing risks of diseases like diabetes, high blood pressure, heart disease, and some cancers. Successful weight loss requires decreasing calorie intake through diet while increasing calorie burn through exercise. Exercise is important for weight loss by elevating metabolism, burning more calories, and releasing endorphins to improve mood. Regular exercise, even light activity, should be enjoyable in order to stick with a routine long-term.
