It's should be obvious that when you reintroduce the diet that caused type 2 diabetes, you'll get diabetes again. Take away the cause and it goes away, reintroduce the cause and it comes back.
I don't know what diet you are referring to. The present diabetic diet guidelines is to include carbs. That will keep type 2 diabetics diabetic. The same diet mainstream doctors refer a diabetic to.
However decades ago the diabetic diet is to eliminate carbs. I remember reading a diabetic cook book from the 1920's which had recipes eliminating all sources of starch, carbs, grains and sugar. It's no medical breakthrough, just forgotten knowledge due to bogus science and conflict of interests
Start your research here, doctor....

Correct me if I'm wrong. If you see what the job of the pancreas is and how it regulates blood sugar and how it's the organ itself that is responsible for regulating your blood sugar you should be able to see it does not all come down to diet but at the end of the day it's how well your pancreas/organ works.
And I'm done with this thread. Go eat a Twinkie or don't. I don't give a shit.
