Is there any scientific evidence that diabetes is never cured, but only in remission?
Yes. Your pancreas would need to be replaced to be cured. The insulin receptors are damaged or dead. When they reach a critical level for your weight, you develop type 2 diabetes. They do not re-grow. Therefore the only cure would be to replace your pancreas. Remission can be achieved through diet (keto is best), intermittent fasting, bariatric surgery, weight loss (so your remaining receptors can handle the load).
“There’s no cure for type 2 diabetes, but losing weight, eating well and exercising can help you manage the disease. If diet and exercise aren’t enough to manage your blood sugar, you may also need diabetes medications or insulin therapy.”

I recently did a lot of reading on this topic.
From what I understand, yes, once the body reaches point of type 2 it never goes back to “normal.” The cells in liver and pancreous that deal with blood sugar are destroyed over a long time of being abused. Once destroyed never regenerate. Blood sugar can be controlled with diet and excercise but those particular cells needed to deal with sugar never come back.
Remission is acheived with dedicated diet modification and excercise. But, much easier for a person to not change his life and take a pill thus the numbers are bad and getting worse every year.
Moral of the story: take care of yourself before it is too late.
