The medicine in the diabetes drug Mounjaro helped people with obesity or who are overweight lose at least a quarter of their body weight, or about 60 pounds on average, when combined with intensive diet and exercise, a new study shows.
The medicine in the diabetes drug Mounjaro helped people with obesity or who are overweight lose at least a quarter of their body weight, or about 60 pounds on average, when combined with intensive diet and exercise, a new study shows.
By comparison, a group of people who also dieted and exercised, but then received dummy shots, lost weight initially but then regained some, researchers reported Sunday in the journal Nature Medicine.
“This study says that if you lose weight before you start the drug, you can then add a lot more weight loss after,” said Dr. Thomas Wadden, a University of Pennsylvania obesity researcher and psychology professor who led the study.
The results, which were also presented Sunday at a medical conference, confirm that the drug made by Eli Lilly & Co. has the potential to be one of the most powerful medical treatments for obesity to date, outside experts said.
“Any way you slice it, it’s a quarter of your total body weight,” said Dr. Caroline Apovian, who treats obesity at Brigham and Women’s Hospital and wasn’t involved in the study.
The injected drug, tirzepatide, was approved in the U.S. in May 2022 to treat diabetes. Sold as Mounjaro, it has been used “off-label” to treat obesity, joining a frenzy of demand for diabetes and weight-loss medications including Ozempic and Wegovy, made by Novo Nordisk.
