Semaglutide 2.4 mg weekly induces mean weight loss of ~15% and enables >20% weight loss in significant patient subsets, significantly outperforming older anti-obesity medications and lifestyle interventions alone.
Semaglutide 2.4 mg, taken once weekly, is a highly effective treatment for obesity, producing an average 15% body weight loss over 68 weeks when combined with lifestyle changes. It significantly outperforms older medications and lifestyle interventions alone, helping to overcome the biological drive to regain weight. This treatment is suitable for adults with a BMI of 30 or higher, or 27 or higher with comorbidities, and requires a gradual dose escalation to manage side effects.
Semaglutide is a newer anti-obesity medication that changes the overall landscape, as phase 3 studies show a mean weight loss near the 15% threshold and significant proportions of patients with a weight loss of greater than 20%.
Why this rating
Based on Phase 3 RCTs (STEP program) with large sample sizes and clear statistical significance.

More from this paper
- Bariatric surgery is currently the most effective treatment for obesity in terms of mortality reduction and comorbidity resolution, but it is restricted to higher BMI classes and not suitable for all patients.Strong
- Older anti-obesity medications (Orlistat, Sibutramine, Phentermine, Naltrexone/Bupropion, Phentermine/Topiramate) achieve mean weight loss between 5-10%, which is often insufficient to meet patient expectations and leads to lower long-term adherence.Good

- 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
