What did her doctors say? Because it seems like most doctors will say it’s not possible. Was she taking medication?
She didn’t take medication at all.
One day, cold turkey, she cut out ALL sugar, pasta, bread (her favorite thing), rice, etc.
She tested her sugar twice a day, which she hated. I’d often have to walk down the road and do it for her. Her sugar level dropped slowly and at a steady pace. Her weight did the same.
Sadly, two years later she died of metastatic breast cancer. I still wonder if the drastic change in her lifestyle had anything to do with it. Probably not.
