If you are eating restaurant salads and wondering why you’re not losing weight, the dressing is usually too blame. Restaurants slather salads with high calorie dressings. Look for a non-cream based dressing, or better yet, go with a vinaigrette. Get your dressing on the side, and dip in the lettuce. You’ll be surprised at just how much is left over. Possible calories cut: 50 to 500 depending on the dressing.
