Fried side dishes -- chili cheese fries, onion rings, and plain old French fries.

Sadly, the most popular vegetable in the U.S. is the French fry, which is loaded with fat, calories, and salt. Most people think nothing of adding a side of 6-ounce fries to their order at McDonald's, even though it adds an additional 570 calories, 30 grams of fat, and 6 grams saturated fat. Sharing a Chili's Awesome Blossom (1/2 portion) gives you 1,355 calories, 101 grams of fat, and 18 grams saturated fat – all before the entree. A serving of Del Taco's chili cheese fries has 670 calories, 46 grams fat, and 15 grams saturated fat, while White Castle onion rings have 750 calories, 39 grams of fat, and 6 saturated fat. "Best bet: Have a side salad with your entrée and skip the high-calorie, deep-fat fried appetizer, and look for something that is not fried and has vegetables," says Hurley. Think bruschetta or edamame.
