GLP-1 receptor agonists (semaglutide, tirzepatide) produce clinically significant weight loss (15-21%) and improve comorbidities, but require long-term continuous use to maintain benefits.
GLP-1 medications like semaglutide and tirzepatide are highly effective for significant weight loss (15-21%) and improving health conditions like diabetes and heart disease. However, they are not cosmetic shortcuts. You must commit to long-term use, as stopping the medication usually leads to regaining the weight. Work with your doctor to manage side effects and adjust other medications as you lose weight.
individuals prescribed the drug semaglutide plus a lifestyle modification intervention for 68 weeks lost an average of 15% of their body weight... average weight loss at 72 weeks was 15%–21%... Maximum weight losses are reached after 12–18 months of continuous use for most individuals, with discontinuation being associated with weight regain for many.

- 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
