Once-weekly subcutaneous semaglutide 2.4 mg and tirzepatide 10-15 mg induce large, sustained reductions in body weight and waist circumference in adults with obesity without diabetes, significantly outperforming lifestyle interventions alone.
For individuals with obesity who have not achieved sustained weight loss through lifestyle changes alone, adding once-weekly semaglutide (2.4 mg) or tirzepatide (10-15 mg) to a lifestyle program can result in significant, clinically meaningful weight loss (12-19%) and waist circumference reduction. These treatments are generally well-tolerated, with side effects typically being mild gastrointestinal issues that diminish over time.
This emphasizes that once-weekly subcutaneous semaglutide 2.4 mg and tirzepatide 10 or 15 mg induce large reductions in body weight and waist circumference and are generally well-tolerated.
Why this rating
Based on a systematic review and meta-analysis of 7 randomized controlled trials (n=5140) with low risk of bias.

- 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
