Tips on achieving a healthy weight
Eat only until you feel satisfied. Begin meals with clear soups, broth or something light. Eat vegetables, grain foods or other starchy foods and protein foods at each meal. Eat slowly so your body has time to know when it's full. Drink 8 glasses of water a day. Exercise. Stock your desk or home cupboards with low-fat snacks. Don't keep high-fat foods in the house. Avoid alcohol. Let yourself indulge now and then. This helps you not feel deprived, which may cause you to eat too much later.
