New generation incretin analogues (semaglutide 2.4 mg weekly and tirzepatide 5-15 mg weekly) produce sustained mean weight reductions of 15-20% in adults with BMI ≥27 kg/m², significantly outperforming older agents and lifestyle interventions alone.
If you have a BMI over 27, talk to your doctor about semaglutide or tirzepatide. These are weekly injections (or oral pills for semaglutide) that help you lose 15-20% of your body weight, which is much more than older drugs. You must also follow a lifestyle plan with diet and exercise.

- 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
