According to clinical trials, tirzepatide is the most effective medication for weight loss that is available right now. There have been several studies on the results of Mounjaro and it outperforms other GLP-1 medications for weight loss results.
One study of over 2,500 patients from July 2022 found an average of up to 20.9% body weight loss in patients on tirzepatide after 72 weeks, compared to semaglutide (Wegovy) where average weight loss was up to 14.9% over 68 weeks.
In the same tirzepatide study, up to 90.9% of patients were able to achieve at least 5% weight loss, up to 83.5% were able to achieve at least 10% weight loss and 56.7% were able to achieve at least 20% weight loss in 72 weeks of treatment.
