Type 2. There is other ongoing research into Type 1. Not a cure, but a stabilization of blood glucose with low carb. Type 1 still need insulin.
I saw a youtube video over the weekend, that was done by two young doctors. Don’t remember their names. But they were both type 1.
They cured their diabetes, or at least managed it better than traditional advice, by going high carb, low fat, low protein. Less than 15% fat and less than 15% protein. And carbs were low on the glycemic scale.
Counter intuitive, but doubt they would lie about it. Their basic claim was that carbs weren’t easily converted into fat, and that if you severely limited fat intake, the cells would burn off their excess lipids even though you were eating carbs.
I’ll look up the video title if either of you want it.
