Introduction
Welcome to The Volumetrics Weight-Control Plan, the first book to use breakthrough new research on the science of satiety to help you control your eating habits. What is satiety? It's the feeling of fullness at the end of a meal, the feeling that you are no longer hungry. The more satiety you feel after a meal, the less you'll eat at the next one.
Satiety is the missing ingredient in weight management. Cut calories by simply eating less, and you'll feel hungry and deprived. You may be able to stick to such a diet for the short term, but to become successful at lifelong weight management, you'll need an eating pattern that lets you feel full with fewer calories.
The primary way to do this is to get smart about your food choices. For any given level of calories, some foods will have a small effect on satiety, others a large one. The right food choices will help you control hunger and eat fewer calories, so you can lose weight, keep it off, and stay healthy.
There's no secret to weight management: Consume fewer calories and burn more in physical activity. You can't lose weight without controlling calories. But you can control calories without feeling hungry. Feeling full and satisfied while eating foods you like is a critical component of our approach to weight management.
The basic strategy of Volumetrics is to eat a satisfying volume of food while controlling calories and meeting nutrient requirements.
The Foods You Choose
Which foods should you choose?
Surprisingly, foods with a high water content have a big impact on satiety. But you can't simply drink lots of water, whichquenches thirst without sating hunger. You'll need to eat more foods that are naturally rich in water, such as fruits, vegetables, low-fat milk, and cooked grains, as well as lean meats, poultry, fish, and beans. It also means eating more water-rich dishes: soups, stews, casseroles, pasta with vegetables, and fruit-based desserts. On the other hand, you'll have to be very careful about foods that are very low in water: high-fat foods like potato chips, but also low-fat and fat-free foods that contain very little moisture, like pretzels, crackers, and fat-free cookies.
Why is water so helpful in controlling calories? It dilutes the calories in a given amount of food. When you add water-rich blueberries to your breakfast cereal, or water-rich eggplant to your lasagna, you add food volume but few calories. You can eat more for the same calories. This property of foods -- the calories in a given portion -- is the core concept of this book. We call it by its scientific term, energy density.
Water is only one of many food elements that affect satiety and energy density. In addition to water, fiber can be added to foods to lower the calories in a portion. It provides bulk without a lot of calories. So by strategically increasing the water and fiber content of meals-with the addition of fruits, vegetables, and whole grains you can dramatically cut the calories per portion -- you lower the energy density. On the other hand, the component of foods that increases the energy density the most is fat. Fat has more than twice as many calories per portion as either carbohydrate or protein. So if you cut fat, you can lower the energy density of a meal. You can combine these strategies: Increase the water and fiber content of foods while lowering the fat content to get satisfying portions with few calories.
This book is based on recent research showing how foods affect hunger and satiety, which in turn has led to new ways to manage weight. Each of the major elements that makes up food -- fat, carbohydrates, protein, water -- has an effect on satiety. So do other dietary components: sugar, fiber, alcohol, and sugar and fat substitutes. In the next part of the book, we explore these influences in detail so you can learn the basic principles of choosing a lower-calorie, more satisfying diet.
Satisfying Portions
If you've suffered through dietary deprivation to lose weight, you may find it hard to believe that you can eat more food, feel full, and still reduce your total caloric intake. To make our program work, some people, if they choose lots of foods that have only few calories in a portion, may actually have to retrain themselves to eat larger portions than they do now.
We won't ask you to greatly restrict your food choices. You won't have to cut out all the fat from your diet, live on rabbit food, subsist on foods on a "free" list, or avoid any food. Volumetrics allows a wide choice of foods. You'll be able to eat bread, pasta, rice, beef, chicken, fish and seafood, dairy products, vegetables, and fruits.
To do so while cutting calories, we'll show you how to make changes such as adding vegetables to a risotto, or choosing fruit over fat-free cookies for dessert. You'll also gain greater understanding of the kinds of foods that are deceptively easy to overeat, whether it's cheese, chocolate, raisins, or pretzels. We won't ask you to ban them. That's not our style, because it's not a style that works. Instead, we will give you specific strategies so you can enjoy them without taking in too many calories. Volumetrics is not really a diet at all, but a new way to choose satisfying, lower-calorie foods.
While we emphasize lowering the energy density of your dietary pattern because that's the best way to eat a satisfying amount of food, we don't want you to get the impression that energy-dense foods are "bad" or "forbidden." Who wants to go through life without chocolate? Favorite foods, even if they are high in energy density, have a place in your dietary pattern. But you will have to plan for them. If you rely on the body's satiety signals to stop you eating chocolate, you'll consume too many calories. So you'll need to satisfy your hunger with foods of lower energy density, and then enjoy high-energy-dense foods in appropriate portions. If the meal itself is satiating, a half-ounce of chocolate is a satisfying ending.

Lasagna can be a heavy, caloric dish. This one is both flavorful and lighter. With plenty of vegetables, the energy density plummets, which allows this tasty version to be made with real Parmesan cheese and lower-fat cheeses, rather than fat-free cheeses, and still provide nearly 1/2 pound per serving for under 250 calories.
Ingredients:
12 uncooked lasagna noodles, cooked and drained
2 teaspoons olive oil
2 cups chopped broccoli
2 cups sliced mushrooms
1 1/2 cups thinly sliced carrot
1/2 cup chopped red or green bell pepper
3 cloves garlic, minced
1 cup sliced green onion
1/2 teaspoon salt
1/2 teaspoon freshly ground pepper
2 cups low-fat (1 percent) cottage cheese
1 cup (4 ounces) shredded part-skim mozzarella cheese
3/4 cup (3 ounces) shredded reduced-fat Jarlsberg cheese or part-skim Swiss cheese
1 (10-ounce) package frozen chopped spinach, thawed and squeezed dry
2 cups commercial fat-free spaghetti sauce
1/4 cup grated Parmesan cheese
Instructions:
Cook the lasagna noodles according to the package directions, omitting salt and fat. Drain and set aside. (If you are using "no-cook" noodles, omit this step.)
Preheat the oven to 375 degrees F.
Heat the olive oil in a large, deep skillet or Dutch oven over medium-high heat until hot. Add the broccoli and the next five ingredients; sauté about 5 minutes. Stir in 1/4 teaspoon salt and 1/4 teaspoon pepper. Set aside.
Combine the cottage cheese, mozzarella cheese, Jarlsberg cheese, and spinach in a large bowl; add 1/4 teaspoon salt and 1/4 teaspoon pepper. Mix thoroughly.
Spread 1/2 cup tomato sauce on bottom of a 13-inch x 9-inch x 2-inch baking dish coated with vegetable cooking spray. Arrange 4 lasagna noodles over the sauce. Top with half the cottage cheese mixture, half the broccoli mixture, and half the remaining spaghetti sauce. Repeat layers, and end with a layer of noodles. Spoon the remaining 1/2 cup spaghetti sauce on the noodles; sprinkle evenly with Parmesan cheese.
Cover with aluminum foil and bake 45 minutes. Let stand 10 minutes before serving. Slice in half lengthwise, then in five equal widths.

Ingredients:
1 tablespoon olive oil
1 1/2 cups sliced mushrooms
1 cup sliced zucchini
1 cup cooked medium barley, made according to package directions but without salt
1 cup chopped red or green bell pepper
1 cup sliced green onion
4 large eggs plus 8 large egg whites (or 2 cups egg substitute)
1 1/4 cups part-skim ricotta cheese
1/2 teaspoon salt
1/2 teaspoon freshly ground pepper
1 (10-ounce) package frozen chopped spinach, thawed and squeezed dry
1 medium tomato, seeded and thinly sliced
2 tablespoons salsa (optional)
2 tablespoons fat-free sour cream (optional)
Instructions:
Preheat the oven to 450 degrees F.
Pour the olive oil into a 9-inch oven-proof skillet or quiche dish. Add the mushrooms and zucchini to the skillet. Bake for 5 minutes in the preheated oven. Remove the skillet from the oven, and layer in the barley, the red pepper, and the green onion over the mushroom-zucchini mixture. Top with tomato slices. Reduce the oven temperature to 400 degrees F.
Combine the eggs and egg white (or egg substitute), ricotta cheese, salt, and pepper in a blender or food processor; process until smooth.
Transfer to a bowl, and stir in the spinach. Pour evenly over the vegetables in the skillet; press down lightly on vegetables to allow egg mixture to seep through layers.
Bake the frittata, uncovered, for 35 minutes or until puffed and set. Let stand 5 minutes before cutting into wedges. If desired, top each serving with 2 tablespoons salsa and 2 tablespoons fat-free sour cream.
Note: If you make this dish with 8 whole eggs instead of egg substitutes or egg/egg white mixture, it adds 30 calories per serving.
