Pharmacotherapy with semaglutide (1 mg/week) and/or metformin (0.5g 3x/day) combined with lifestyle interventions produces weight loss comparable to low-carbohydrate diets and balanced diets at 3 months, despite potentially faster initial results.
Pharmacotherapy (semaglutide/metformin) combined with lifestyle changes is an effective weight loss strategy that yields similar results to dietary changes after 3 months. It is not just for 'severe' cases but can be a valid option for those struggling with diet alone.
ModerateSupportsMEDIUM confidence
At 2 months, patients who received the low-carbohydrate diet (8.86 (6.45, 10.84) %) and pharmacotherapy (8.16 (5.79, 9.68) %) achieved a higher percentage weight loss than those who received balanced dietary guidance (6.77 (3.72, 8.65) %) (P < 0.01). At 3 months, there was no significant differences among groups for the percentage of weight loss (P = 0.362).

- 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
