If you consider yourself cured, then you're cured.
If you consider your diabetes in remission, then it's in remission.
If you consider your diabetes reversed, then it's reversed.
If you consider yourself to be a well controlled type 2 diabetic, then you are a well controlled type 2 diabetic.
The only way I could discover if I really have no more insulin resistance would be to eat carbs for a few weeks until my physiological insulin resistance due to a zero carb diet should have gone away and see what my blood glucose levels are like. I have no intention of ever doing that, so I'll never know. Perhaps low carb (or zero carb) is just an end run around type 2 diabetes, but that's good enough for me. Personally, I don't consider the "healthy plate" or the typical western diet to be healthy for anyone in the long run, regardless of blood glucose levels. In other words, just because a person has non-diabetic blood glucose levels doesn't mean they are healthy. So I will not be going back to that way of eating even if I could with respect to my blood glucose levels.
