Metformin provides modest weight loss (average ~2.1 kg/year) and improves insulin sensitivity, making it a first-line treatment for T2DM, though it is not FDA-approved specifically for weight loss.
Metformin is a standard first-line medication for Type 2 Diabetes. It helps control blood sugar and may lead to modest weight loss (about 2 kg per year), but it is not a powerful weight-loss drug. It is generally safe and well-tolerated, though some people experience gastrointestinal side effects.

According to the Diabetes Prevention Study (DPP), which is the largest study to show the weight benefits of metformin, the average weight reduction after one year on the medicine is only 2.1 kg [30].

- GLP-1 receptor agonists (e.g., semaglutide, liraglutide) and dual GIP/GLP-1 agonists (e.g., tirzepatide) induce significant weight loss and improve glycemic control by acting on multiple pathways including appetite suppression, delayed gastric emptying, and improved adipose tissue health.Strong
- Bariatric surgery (e.g., Roux-en-Y gastric bypass, sleeve gastrectomy) is an effective treatment for obesity and T2DM, capable of inducing remission of diabetes through both weight-loss-dependent and weight-loss-independent mechanisms.Strong
- Sustained weight loss of at least 15% significantly improves glycemic control, reduces cardiometabolic risk, and can induce remission of Type 2 Diabetes (T2DM).Good

- 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
