Potato chips are a popular snack food that come in a variety of savory flavors in convenient package sizes. Like most people, if you've had one, you know that it's very easy to continue eating several or even a whole bag. A study on weight loss and lifestyle published in the "New England Journal of Medicine" determined that potato chips are the greatest culprit in long-term weight gain because of their high content of simple carbohydrates. You don't have to give up this addictive snack completely, though; there are other types of chips that contain more complex or slow carbohydrates.
