Results: The mean weight loss in the metformin treated group was 5.8±7.0 kg (5.6±6.5%). Untreated controls gained 0.8±3.5 kg (0.8±3.7%) on average. Patients with severe insulin resistance lost significantly more weight as compared to insulin sensitive patients.

In a much larger trial in over 4,000 people with type 2 diabetes, it was found metformin use was associated with a 2.4 kg (roughly 5.3 lbs) weight loss over a four-year period. There are a few ways that metformin might impact weight. One is that the medication can reduce your appetite.
Due to the modest and inconsistent effects of weight loss the FDA has not approved metformin as a weight loss agent.

How quickly does metformin work for PCOS? Most medical providers start patients on lower doses of metformin to reduce the severity of side effects. Though each person responds differently, it may take 1-2 weeks or longer to work up to an effective dose.
