GLP-1 receptor agonists (semaglutide, tirzepatide) produce 15–25% mean weight loss and reduce cardiovascular events by 20% and type 2 diabetes incidence by 72%.
If you have obesity or overweight with a related health condition, GLP-1 medications like semaglutide (Wegovy) or tirzepatide (Zepbound) are currently the most effective pharmacological treatments, offering 15-25% weight loss and significant cardiovascular benefits. These require weekly injections (or oral forms for some) and work best when combined with a modest caloric deficit and regular exercise. Be aware of potential gastrointestinal side effects and the need for long-term management, as stopping the medication often leads to weight regain.
These agents demonstrate unprecedented efficacy, achieving 15–25% mean weight loss in clinical trials, alongside reducing major adverse cardiovascular events by 20% and T2D incidence by 72%.
Why this rating

- 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
