If you’re overweight or obese, it’s best to start by taking steps to lose weight through nutrition and exercise. Aim to lose 5% to 10% of your body weight is the first goal. While this may seem small, research shows that even losing 5% to 10% of your weight is beneficial. Most hospitals and health care organizations have specialists such as a dietitian who can provide weight management advice and treatment.
