Tirzepatide (up to 15 mg weekly) achieves the highest mean weight loss (up to 20.9%) among current pharmacotherapies but lacks FDA approval for cardiovascular risk reduction.
Tirzepatide (up to 15 mg weekly) offers the highest weight loss potential (up to 20.9%) among current drugs. However, it is not yet FDA-approved for cardiovascular risk reduction. Titrate the dose slowly to manage gastrointestinal side effects.

Tirzepatide leads at 20.9%, though it lacks FDA approval for CV risk reduction or adolescent use [56]. In SURMOUNT-1... tirzepatide led to 15.0-20.9% weight loss vs. 3.1% with placebo over 72 weeks...
Why this rating
Supported by large RCTs (SURMOUNT-1, 2, 3, SUMMIT) with significant results.

- 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
