I've been able to reduce my diabetic glucose levels to pre-diabetic/near normal, which I'm now maintaining by diet alone. I believe my diabetes was triggered in part by eating an unnaturally (and probably unhealthy) high carbohydrate diet, which my body ended up unable to cope with. Reverting to a lower carb diet - a somewhat stricter version of what I'd always eaten previously for around 70 years - has enabled me to maintain these lower glucose levels for nearly 10 year now, and going by my results my GP eventually decided I could manage without diabetic medication.
For me, limiting carbs is more about eating sensibly (diabetes or not!) rather than "controlling remission", and lower glucose levels are simply one of several benefits of my doing so.
There's no real necessity at all to stuff our faces with the (often) huge quantities of carbs we've been conned into believing that we should consume, as our bodies use both carbs and fats as fuel. Since we only require around 120-130g glucose (either converted from carbs or generated by our livers) for certain brain functions, we can use fat for our main source of energy - or only source as our carnivore members can confirm!...
