Take a look at almost anyone’s refrigerator door and you will likely find a bottle (or two or three) of their favorite salad dressing. Which one do you choose when you are at the grocery store? What makes you buy that one in particular? Maybe the manufacturer has cleverly marketed the products to give the perception that after eating some fresh salad greens lightly tossed with this specific dressing, a slimmer waistline will naturally result.  Good luck!
