My husband was diagnosed as type 2 diabetic when he turned 55 years, and has gradually moved up the "ladder" with his medications. However 10 years ago (when he was 70) I dropped all grains and sugars (lowcarb eating) and he ate the same things that I was to encourage me.
After a few months on Atkins his numbers dropped right down to the normal range and for a time he was taken off all his metformin etc as he exhibited no signs of being diabetic.
Unfortunately he never really looked into the theory of lowcarb eating or liked the foods I ate much, so bit by bit he went back to eating bread, porridge, marmalade, chips, sugar etc and is now back to taking metformin and glipizide to keep his numbers "normal".
Several diabetes specialists in USA nowadays recommend eating lowcarb (or at the least dropping all grains and sugar) and it seems their patients often reverse the process by following their advice.
Maybe if you have time do some googling for "diabetes and Atkins" or "Diabetes and Low carb eating" to see if it seems to be something you might want to experiment with.
