For those watching their waistlines and their wallets, frozen versions of popular restaurant foods are tempting solutions. But think twice before replacing your favorite take-out with its frigid counterpart--the swaps aren't always so diet friendly. Here, a look at the frozen foods that don't do your body good.

1. Breakfast sandwiches. Popping it into the microwave instead of picking it up from a fast food restaurant drive-through doesn't make a breakfast sandwich a healthy way to start your day. Be especially wary of the kinds that use French toast as bread. One Aunt Jemima brand Sausage and Egg on French Toast sandwich weighs in with 20 grams of fat, 8 of which are saturated. Translation? Not quite the breakfast of champions.

2. Mac and cheese. Whether it's homemade or from a grocery store, mac and cheese is the ultimate comfort food. But this ooey, gooey goodness doesn't come without a price, especially if it's of the frozen variety. One 10-ounce portion of Stouffer's macaroni and cheese serves up 350 calories, 17 grams of fat, and a whopping 920 milligrams of sodium--double those numbers if you decide to eat the whole box.

3. Sundae cones. A pre-packaged bar or cone might seem slightly less dangerous than a never ending carton of ice cream. After all, if you're limited to just one portion, how much damage can you really do? More than you might think. These all-inclusive cones are often loaded with fudge, caramel, and nuts, packing in more calories than two servings of some kinds of regular ice cream. One Nestlé Vanilla Caramel Drumstick contains 440 calories, 19 grams of fat, and 40 grams of sugar, your entire recommended daily allowance (RDA), according to the U.S. Department of Agriculture (USDA). 

4. Pizza. Greasy, fatty pizza is already known to destroy diets, and those of the frozen variety don't help its reputation. Loaded with sodium and an abundance of fat-laden meets and cheeses, their crusts are often so thick that the dough alone adds hundreds of calories per serving. Most of the 410 calories in one Stouffer's French Bread Cheese Pepperoni Pizza come from fat (20 grams). With 810 milligrams of sodium, this pizza doesn't skimp in that department either.

5. TV dinners. More than 30 years after they were first introduced, TV dinners are still popular, perhaps due to their nostalgia factor. But proceed with caution. These tasty and convenient microwaveable meals may be brimming with sodium and fat, especially the ones that come in supersized versions. If getting 90 percent of your RDA of sodium in one sitting sounds tempting, try pairing your favorite sitcom with a Swanson Hungry-Man Fried Chicken dinner. With 2,160 milligrams of sodium in just one serving, watch out for rising blood pressure.

6. Breakfast pastries. They're toasty, warm, and delicious, but breakfast pastries aren't as nice and sweet as they seem. The 200 calories and 10 grams of fat in just one little Pillsbury Strawberry and Cream Cheese Toaster Strudel could wreak havoc on your waistline--and send you into sugar shock as well.
