Normal A1c is 5.7% so you are just into prediabetes. Basically cutting or stopping things like potatoes, veggies that grow under the/inside ground (starchy carbs), most fruit except berries and the occasional apple, pasta, rice, pastries, pies, cakes, sweets, sugar - the hidden carbs in prepared food. Some of these will cause a blood sugar spike, this we check by using a BG meter (in most areas type 2's have to buy their own, alas) - if it gives a spike, either reduce the portion size or find a replacement that works better (ie cauliflower rice for real rice), there are plenty of alternatives to try. Lowering your carbs will also help you lose weight if you need to, plus do more exercise if you can, every bit helps.
I think I have said enough to begin with, others will no doubt drop in with their own experiences, questions, advice and support. You are in the best place here 🙂
