Most people with type 2 diabetes struggle with their weight. And chances are, your doctor has given you little or no guidance on how to shed those extra pounds. But doing it will likely make your blood sugar easier to control and can lower your blood pressure and cholesterol, too. In many cases, doctors will allow patients who lose a significant amount of weight to cut back on—or eliminate—some of their medications. The best way to lighten your load? Steer clear of the hype and stick to proven strategies.
