Triple agonist Retatrutide (12 mg/week for 48 weeks) and dual agonist Tirzepatide (15 mg/week for 72 weeks) produce superior weight loss (24.2% and 20.9% respectively) in adults with obesity compared to traditional anti-obesity medications, with even greater effects in those with BMI ≥ 35 kg/m².

Newer drugs like Retratrutide (triple agonist) and Tirzepatide (dual agonist) offer significantly higher weight loss (20-26%) than older drugs. Retratrutide 12mg weekly for 48 weeks and Tirzepatide 15mg weekly for 72 weeks are key examples. These are more effective than traditional options, especially for those with BMI ≥ 35, but cost is a major barrier.

GoodSupportsHIGH confidence
Retratrutide – a triple agonist of the glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon receptors – at a dose of 12 mg for 48 weeks has been recently associated with a remarkable 24.2% weight loss in adults with obesity... Interestingly, patients with BMI ≥ 35 kg/m² had an even greater weight loss (26.5%)... Tirzepatide, a dual GIP and GLP-1 receptor agonist, at a dose of 15 mg for 72 weeks, has also been associated with important weight loss (20.9%) in people with obesity

Why this rating

Based on cited Phase 2/3 trials (references 7, 8) which are high-quality RCTs, though specific extreme obesity subgroup data is limited.
