New generation obesity medications (GLP-1/GIP agonists) achieve mean weight loss of 15–25% over 68–72 weeks, narrowing the efficacy gap between medical and surgical management of obesity.
New GLP-1/GIP medications like semaglutide (2.4mg weekly) and tirzepatide are highly effective, producing 15-25% weight loss over ~1.5 years. This efficacy is now comparable to surgery, making medication a primary, not just secondary, option for obesity treatment.

- Combining obesity management medications (OMM) with metabolic bariatric surgery (MBS) or endoscopic procedures is an inevitable and necessary component of future personalized obesity care, though optimal protocols are currently undefined.Moderate
- Post-bariatric surgery weight regain (affecting 15-20% of patients) can be managed with endoscopic interventions or OMM, but optimal dosing and scheduling for these combination therapies remain undefined.Moderate

- 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
