I wish I could tell you that you could cure your diabetes through just losing weight, but sadly it is more complicated than that. Often the weight is a complication of diabetes. Type 2 diabetes can cause your insulin to run high and your high blood sugars at the same time just pack on the body fat. So no, I don't believe your diabetes is cured. If you return to your old diet, your blood sugar will rise and diabetes will raise it's ugly head. That being said, I do believe that a good diet can make a world of difference in controlling your diabetes. And yes, I think that if you are lucky, you might be able to keep up the diet, get off your meds and control your diabetes for a while. Heck, maybe a long time. But in the end, what really matters is that you keep your blood sugar controlled. If you can do that with just diet great, but if you need meds, then that is ok too.
