An experimental drug to treat type two diabetes may also help with weight loss.
In a Danish study of 564 obese adults, those who took Liraglutide for 5 months lost about 15 pounds, compared to an average of 6 pounds in a placebo group.
The participants also restricted their diets and added exercise to their routines.
The drug, which is given by injection, also reduced blood pressure.
It's approved to treat Type 2 diabetes in Europe, and is under review by the U.S. Food and Drug Administration.
