Do you feel tired all the time? Do you feel hungry between meals, even if you've just eaten? Do you crave candy, soda, or coffee, especially in the mid-afternoon?

If you answered yes to any of these questions, you may have a metabolic disadvantage. Most diet plans fail because they don't address the underlying metabolic conditions that contribute to increased hunger and weight gain. In fact, they often worsen the problem by cutting calories and prompting food cravings. This further stresses your metabolism and leaves you hungrier—and heavier—than ever.

The Stubborn Fat Fix remedies this by identifying and treating metabolic imbalances. Based on the results of simple quizzes, you'll choose between two eating plans that prescribe the ideal foods needed to repair your metabolic disorder and turn off faulty hunger signals. On both plans, you'll lose weight by doing something that seems counterintuitive—eat more, move less—in order to heal your metabolism. You can even incorporate "luxury" foods—indulging in ice cream, salty snacks, bread, wine or beer, or even chocolate—to stay on track without feeling deprived. A tailored supplement program, carefully controlled exercise, and stress-reduction techniques complete the metabolic cure.

Even better, once your metabolism is in balance, you will not only permanently drop pounds but also improve your cholesterol, blood pressure, blood sugar, and energy levels for overall better health. Hundreds of the Berkowitzes' patients, like those profiled in the book, have successfully lost up to 70 pounds with this plan.

With The Stubborn Fat Fix—featuring more than 30 delicious recipes and the exclusive Fiber Ratio tool created by Valerie to help you get the most out of your favorite foods—you, too, can lose that stubborn fat forever.
