{description}If you are sitting in a room right now with two other adults, statistically one of you should be overweight or obese. Obesity is a serious and growing health threat, and it usually leads to other health problems such as high blood pressure and diabetes.  There are many approaches to treating obesity:  some involve personal initiative such as exercise and diet, and others involve medical intervention through weight-loss drugs or surgery.  The possible value and effcacy of these two approaches are actively researched at the Stanford Medical Center, where teams of doctors and scientists are attempting to fgure out the best educational programs to promote exercise and potential candidate drugs for suppressing appetite.  {/description}
