Who doesn't love Denny's? Now you know what you should and shouldn't order...

Eat This:

• Two fried eggs with grits and grapefruit juice. Grapefruit juice is a great source of vitamin C and lycopene, but if you're fighting the sniffles, beware - compounds in the fruit render allergy-fighting medicines such as Allegra nearly powerless.
• Veggie-Cheese Omelette made with Egg Beaters.
• Grilled Tilapia Dinner with rice, vegetable blend and sliced tomatoes.
• Vegetable Beef Soup

Not That!

• Buttermilk pancake platter with whipped margarine and maple syrup. With 119 grams of carbs, the pancake platter creates an early morning spike in your insulin levels, which signals your body to start storing fat.
• Smoked sausage scramble.
• Fish sandwich with seasoned fries.
• Clam chowder.

Weapon of mass destruction:

• Mini burgers with onion rings. Don't be fooled by the diminutive name: With more than a day's worth of calories and saturated fat, these minis do massive damage to your gut. In fact, 4 of Denny's 6 burgers contain more than a day's worth of fat.

Guilty pleasure:

• Country fried steak and eggs. Drop the hash browns and this hearty breakfast packs major protein for 200 calories less than the Original Grand Slam.
