Can fast food be part of a healthy-eating plan? Sure, if you order wisely and choose fast food only occasionally. Choose an entree salad with grilled chicken, shrimp or garden vegetables. Opt for fat-free or low-fat dressing on the side, rather than regular salad dressing, which can have 100 to 200 calories per packet. Watch out for high-calorie salads, such as those with deep-fried shells or those topped with breaded chicken or other fried toppings. Also skip salad extras, such as cheese, bacon bits and croutons, which quickly increase your calorie count.
