Yes, I have a PCOS weight loss success story. ...Just not with Metformin.
I was diagnosed about 20 years ago, or so. The only symptom I had was the inovulatory dysfunction. I weighed 97lbs from age 16 to age 30 or so.
In my 30s, I went up to 110lbs, but that was good. Then, boom, around age 40, my periods became regular, but I started packing on the weight. By my mid-40s, I was over 160lbs!
Diet & exercise didn't work. In fact, I often gained weight with caloric restriction...
