A diabetes drug called tirzepatide can help people lose up to 21% of their body weight, but the weight loss tends to stop increasing too soon — especially for those with type 2 diabetes.

People with obesity or type 2 diabetes who take tirzepatide are much more likely to lose a meaningful amount of weight—like 5%, 10%, or even 15% of their body weight—compared to those who don’t, and the more they take, the better the results seem to be.
