Diet!: There are no easy answers. A healthy low-glycemic index diet and exercise is the best option for losing weight. Weight watchers has been shown to be effective in many studies. Speak with your doctor, consider seeing a reproductive endocrinologist for more options. Although metformin is not indicated for weight loss, it can lower Insulin resistance which may help diet and exercise work better.
