The best way to treat obesity is to eat a healthy, reduced-calorie diet and to exercise regularly. To do this you should: •eat a balanced, calorie-controlled diet as recommended by your GP or weight loss management health professional •join a local weight loss group •take up activities such as fast walking, jogging, swimming or tennis for 150-300 minutes a week •eat slowly and avoid situations where you know you could be tempted to overeat. You may also benefit from psychological support from a trained healthcare professional, to help change the way you think about food and eating.
