So if you are now in the diabetic range you can easily get your blood sugar back down. The best way I know is to go low carb, cut out bread, pasta, rice, potatoes, sugar and other high carb foods. Instead eat healthy fats and low or unprocessed meat and fish, eggs, cheese, etc. I added plenty of green veg, riced cauliflower plus a few berries with full fat Greek yogurt. And got my carbs low enough that I could have a couple of squares of 85% chocolate.
Now I'm in remission I have a few more carbs but still avoid sugar and high carb foods.
