A low carb diet (or at least a reduced one) is the way to go. Add some exercise and you may never become truly diabetic. Start by cutting out all the obvious sugar from your diet and definitely test your blood sugars. I can't advise on test kits, because my husband was one of those rare and lucky T2 diabetics given infinite and everlasting supplies by his GP (we put it down to an administrative error!)
Do read up on low carb diets, there's lots on this forum and the DietDoctor.com is a good source.
