Tirzepatide increases the likelihood of achieving clinically meaningful weight loss thresholds (≥5%, ≥10%, ≥15%) in a dose-dependent manner, with 15 mg showing the highest odds ratios for all thresholds.
Higher doses of tirzepatide significantly increase your chances of losing 5%, 10%, or 15% of your body weight. The 15 mg dose offers the highest probability of achieving these milestones compared to lower doses.

Tirzepatide also markedly increased the odds of achieving clinically meaningful weight loss: ≥ 5% (OR=11.32; p < 0.0001), ≥ 10% (OR=14.77; p < 0.0001), and ≥ 15% (OR=18.07; p < 0.0001).
Why this rating
Based on the same robust meta-analysis of 11 RCTs.

More from this paper
- Tirzepatide induces significant, dose-dependent weight loss in patients with obesity or type 2 diabetes, with non-diabetic individuals experiencing greater absolute weight reduction than diabetic individuals at equivalent doses.Strong
- Tirzepatide is associated with a higher incidence of gastrointestinal adverse events (nausea, vomiting, constipation, dyspepsia) compared to placebo, which increases with dose and leads to higher discontinuation rates, but does not increase the risk of serious adverse events.Strong

- 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
