Losing weight with metformin

I am a diabetic and am wondering how much weight I can lose with metformin?

Metformin has been around for decades and is a relatively safe drug for type 2 

diabetes. More important, it should be the drug of first choice; it is cheap, readily available and works great. In the last decade, many papers have been published regarding metformin and its ability to induce weight loss. First, there is no doubt that metformin can induce weight loss in diabetics. However, diabetics have to be realistic. You are not going to lose weight simply by taking metformin and sitting on the couch; you have to change your life style and also exercise. Alone metformin does not decrease weight, it is not a weight loss drug nor has it ever been prescribed for weight loss. The weight loss by metformin is mild. You may lose 1-2 pounds month but you will need to exercise to reach that level. If you think by popping metformin and watching TV you are going to lose weight, you are sadly mistaken.
