There’s more to dieting than counting calories – if you make healthy choices that fill you up, you’ll eat less. Weight Watchers’ PointsPlus program, launched in November 2010, assigns every food a points value, based on its protein, carbohydrate, fat, fiber, calories, and how hard your body has to work to burn it off. Choices that fill you up the longest “cost” the least, and nutritionally dense foods cost less than empty calories. So if you’re wavering between a 200-calorie fruit smoothie and a 200-calorie iced coffee, the smoothie is the smarter choice.
