If you want to lose weight but must appease your sweet tooth from time to time, Richard Simmons is on your team. Sweetie Pie is a collection of delectable, reduced-fat and reduced-calorie desserts. Most get 30 percent or fewer calories from fat. But Simmons is quick to point out that you can't scarf down half a cake and expect to lose weight. The key, he says, is handling dessert "with respect," which means eating it on special occasions and having only a serving. You'll find adaptations of all your favorite desserts, such as brownies, lemon bars, biscotti, chocolate layer cake (19 percent fat), Boston cream pie, chocolate mousse pie, and even lollipops. You'll also find desserts only Richard Simmons might create, like "Brownie Pizza." Watch out--the last chapter presents six of Simmons's "all-time favorite outrageous desserts," fat and all. Simmons's running commentary of his personal relationship with these desserts is entertaining enough to read whether or not you want to prepare the recipe. Recipes include nutritional breakdown (calories, protein, fat, carbohydrate, sodium, and cholesterol), plus fat and calorie comparisons with standard versions. The photos will make your mouth water. --Joan Price
