I can tell you what my wife's experience was. Diagnosed with an A1C about 9.5, glucose level in the 230's. She also has some neuropathy in her foot, that at the time she didn't mention. First diagnosed 9 years ago with her Medicare wellness check up. Initially we did what the dietician and doctor recommended. She was on oral medication and we watched the carb intake as recommended. She did get her A1C down in the 6.6- 7 range, I don't remember exactly. That took about a year and on medications. Counting carbs also resulted in calorie restriction so she did loose some weight.
About 18 months later after having my own cardiac health problems I was looking for recipes I encountered the plant based folks which also lead to vegan dietary results in type 2 diabetics and neuropathy. I asked her if she'd like to try low fat vegan for 2 weeks and see if it helped. I was going to see if I could do it for 2 weeks. About a year later she was off all her meds and had a slight improvement in the numbness in her foot. Her A1C is usually 4.9-5 and her fasting glucose is in the 80's. She is still vegetarian, mostly eats a vegan low fat diet because 7 years later, I still eat a vegan low fat diet.
By mostly vegetarian I mean she has some cheese on her pasta maybe 3-4 times a year, and I know she's had some milk chocolate, but that's it.
I can go into a whole lot more detaisl if you're interested. Please keep in mind this is just our story. Amoung her siblings 2 developed type 2, one of which suffered tremendously before her death ( motovational factor) and the other is managing ok, but her numbers are still in the diabetic range. She's an omnivore. Two of her other sisters never developed diabetes, and had active lifestyles. This is good evidence that in my wife's instance it was a life style result.
Now some questions. What are you eating now? Are you overweight? Do you test your blood glucose? Are you on other medications? Do you have a family history of diabetes?
I think a good place to start would be a discussion about what you actually eat now.
All the best, Bob
