Key Lime Mousse Pie with just 88 calories and 6 grams of fiber. Chicken nuggets made with crushed barbecue chips. Faux-fried zucchini with 9 grams of fiber and only ½ gram of fat.

These are just a sampling of the low-fat, low-calorie and high-fiber recipes found in Lisa Lillien's second cookbook, "Hungry Girl: 200 Under 200" (St. Martin's Griffin, $19.95).

In 2004, Lillien started Hungry Girl, a Web site dedicated to helping dieters by providing product news and reviews, recipes and inspiration and daily free e-mail to more than 650,000 subscribers. Lillien makes it clear she's not a doctor, chef or nutrition professional.

She's just a hungry girl obsessed with food, who, like many other yo-yo dieters, says she struggled to lose the same 15 pounds for much of her life. Once Lillien, 43, of Encino, Calif., lost 25 pounds by changing her lifestyle, she realized she had to stick with it.

Those changes morphed into www.hungrygirl.com, and "Hungry Girl: Recipes and Survival Strategies for Guilt-Free Eating in the Real World" (St. Martin's Griffin, $17.95). It spent 6 months on the New York Times Best Sellers list.

Cutting the fat and calories, Lillien relies on the obvious, such as using egg whites instead of whole eggs, sugar substitutes and reduced-fat or fat-free products.

Fans of Hungry Girl will like the book's breezy style. If you try Lillien's recipes, be prepared to stock your pantry with her recommended fat-free, reduced-fat and high-fiber products.

KEY LIME MOUSSE PIE

Serves: 8 / Preparation time: 15 minutes

Total time: 1 hour (plus chilling time)

CRUST

¼ cup light whipped butter or light butter spread

2 tablespoons water

1 ¾ cups original Fiber One bran cereal

4 no-calorie sweetener packets

1 teaspoon cinnamon

FILLING

1 cup boiling water

1 small (4 serving size) package sugar-free lime gelatin

1 no-calorie sweetener packet

½ cup cold water

1 ½ tablespoons lemon juice

¼ teaspoon vanilla extract

2 cups fat-free whipped topping

Preheat oven to 350 degrees.

In a microwave-safe bowl, combine the butter with the water. Microwave until the butter is just melted.

In a medium mixing bowl, combine the cereal crumbs with the butter mixture, sweetener and cinnamon. Stir well until mixed.

Spray a 9-inch pie dish with nonstick cooking spray. Press the crumb mixture into the bottom and up the sides of the dish. Bake 10 minutes, remove from oven and cool.

Meanwhile, in a medium mixing bowl, combine the boiling water with the gelatin and sweetener. Stir the mixture for 2 minutes or until the gelatin is completely dissolved. Add the cold water, lemon juice and vanilla extract; mix well.

Refrigerate for about 45 minutes or until slightly thickened, but not set.

Once the gelatin is thickened slightly, stir in the whipped topping. Whisk until thoroughly blended; pour the mixture into the pie crust.

THE HUNGRY GIRL'S MEAL-PLANNING STRATEGIES

For Lisa Lillien, the light bulb went off in her head when she was taking pastries to be analyzed at a food lab because she didn't believe the nutrition label. She thought she could help people by sharing what she'd learned.

Her Hungry Girl persona evolved from that desire.

Lillien's Web site, www.hungrygirl.com, offers advice and product news for dieters. I caught up with Lillien by phone to talk about the Hungry Girl approach.
