Long-term use of GLP-1 receptor agonists (semaglutide 2.4mg or tirzepatide 15mg) produces significant weight loss (4-21%) and improved cardiometabolic markers, but discontinuation leads to rapid weight regain and increased cardiac risk.
GLP-1 agonists like Wegovy and Mounjaro are highly effective for significant weight loss (up to 20%) when taken long-term. However, they are not a 'cure'; stopping the medication typically results in weight regain and increased heart disease risk. If you use these, view them as a long-term tool alongside lifestyle changes, not a quick fix.
GoodSupportsHIGH confidence
patients who discontinued the medication had a 30–33% increased risk of cardiac disorders compared to patients who continued to take the medication... patients with diabetes on average were able to lose 4–6.2% of their total weight (and nondiabetics up to 17.4%) with long-term (>1 year) use of this medication... discontinuation results in weight gain.
Why this rating
Based on multiple Phase 3 RCTs (STEP, SURPASS) and observational studies cited.

- 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
