The new diabetes drugs: Your best shot for weight loss?

Several drugs originally developed to treat type 2 diabetes can help people shed as much as 20% of their body weight—far more than other anti-obesity drugs. Known as incretin mimetics, they also improve blood pressure and cholesterol levels. Up to half of all new-onset diabetes cases in this country are linked to obesity, a disease that now affects more than 40% of Americans. Both conditions are closely linked to cardiovascular disease.
