In 1999, almost 108 million adult
Americans were overweight or obese. If you are overweight or obese, carrying
this extra weight puts you at risk for developing many diseases, especially
heart disease, stroke, diabetes, and cancer. Losing this weight helps to
prevent and control these diseases. The NHLBI guidelines provide you with a new
approach for the measurement of overweight and obesity and a set of steps for
safe and effective weight loss.
