Can Metformin Cause Weight Loss?
Medically reviewed by Lauren Okafor | MD, The Frank H Netter MD School of Medicine, Loyola University Medical Center on August 22nd, 2026.
Yes, metformin can cause modest weight loss, typically 2-6 pounds over 6-12 months. This diabetes medication works by reducing glucose production in the liver and improving insulin sensitivity, which can lead to decreased appetite and caloric intake. Studies show that metformin users lose an average of 2-3% of their body weight, with some experiencing up to 10 pounds of weight loss. The weight loss effect is generally more pronounced in people with insulin resistance or prediabetes. While not primarily a weight loss drug, metformin's metabolic benefits make it a valuable tool for weight management. We can help you understand if metformin might be appropriate for your weight loss goals through a personalized consultation.
