I didn't read the story because of addblock but I've seen headlines like this before. As someone with type 2 they always annoy me. I've been eating low carb for a long time (sometimes more successfully than others) and while I can keep my blood sugars under control with the diet, and hopefully keep my body from further damage, I have not "cured" my diabetes.
If I eat a high carb meal, my blood sugar will shoot up way higher than that of a normal person. I still have diabetes. Eating low carb is not curing me, but it is helping me keep things under reasonable control.
