Tirzepatide, a dual GLP-1/GIP receptor agonist, produces significantly greater body weight reduction (up to 20.9% at 15mg) compared to semaglutide and other GLP-1 agonists in patients with obesity, with real-world studies confirming superior efficacy.

Tirzepatide (up to 15mg once weekly) is the most effective current pharmacological treatment for obesity, producing up to 21% weight loss. Real-world data shows it outperforms semaglutide. Discuss side effects like nausea with your provider, and consider cost-effectiveness as data is still emerging.

SURMOUNT-1... percentage change in body weight compared to the baseline was... 20.9% with tirzepatide 15 mg... Evidence retrieved from systematic reviews and meta-analyses of relevant RCTs in the field have suggested that tirzepatide provides significantly greater body weight reduction compared to GLP-1 receptor agonists... patients assigned to tirzepatide had a significantly greater weight loss compared to those administered semaglutide (15.5% versus 10.3%, respectively)
