Book excerpt: There are many diet books in print today, each designed to assist people in losing weight. Although they are all different, most of them work on a principle such as "low fat" or "low carbohydrate." The PVC Diet should not be looked upon as a diet, but rather as a simple set of rules designed to assist you in choosing your food. We have to eat every day and many of us need advice. Forget counting fat grams! They are not counted in this diet. The only thing you need to remember is PVC, three easy letters that will steer you to the correct selection of food for weight control as well as overall health.
