Are you buying those expensive no-fat products but gaining weight? You've switched to frozen dinners with hardly any fat and eat only no-fat cookies, but your weight hasn't changed? You are not alone. Remember that fat, besides delivering terrific texture for a product, is also a bulking agent. Taking out the fat requires replacing it with another bulking agent. A lot of the time, it's sugar! Check out the ingredients and calorie counts; you might be surprised. You might be better off eating smaller portions of the "regular" version.
