Metformin is a medication to treat diabetes. It is not a diet pill, nor should you expect it to help you lose weight even if you are taking it for diabetes. As far as using it for dieting, it may change the way your body uses sugars for energy, but it alone is not going to help in a weight loss battle.
I am diabetic, and I take metfomin; what I have noticed as far as losing weight is that I can drop it IF I keep tabs on my carbohydrate intake. It is a fact that carblhydrates affect the ability of your body to create it's natural insulin; and it is known that keeping your carbohydrate intake down to a certain range can dramatically help in a weight loss battle.
Since May, I have been simply substituting carbs with more protein (instead of mashed potatoes, I eat and extra serving or two of vegetables and more meat), and so far, I am up to a 47 pound weight loss.
Hope that helps.
