The skinny on being underweight

If being too fat is a health risk, you might think being too thin is good for you. But contrary to that old adage, "you can never be too rich or too thin," being overly skinny carries its own health risks.

If you're trying to gain weight, it may seem logical to load up on fattening foods like burgers, fries, chips, and chocolate. But just because you are thin doesn't mean you aren't at risk for conditions such as heart disease, and these types of foods are often rich, not only in calories, but in artery-clogging fats.
