In real-world clinical practice, tirzepatide produces significantly greater weight loss and higher rates of achieving 5%, 10%, and 15% weight reduction thresholds compared to semaglutide in adults with overweight or obesity.
If you are choosing between semaglutide and tirzepatide for weight loss, real-world data suggests tirzepatide is likely to produce roughly double the weight loss at one year compared to semaglutide. You are also significantly more likely to hit major weight loss milestones (5%, 10%, 15%) with tirzepatide. However, this comes with the caveat that these specific findings are based on formulations labeled for Type 2 Diabetes, and insurance coverage may be more difficult to obtain for tirzepatide than semaglutide.
In this large, propensity-matched, real-world analysis, individuals with overweight or obesity treated with tirzepatide were significantly more likely to achieve clinically meaningful weight loss and larger reductions in body weight compared to those treated with semaglutide.
Why this rating
Large sample size (n=41,223), rigorous propensity score matching, and real-world applicability, though it is an observational study (preprint) rather than a head-to-head RCT.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
