Being diabetic is a very complex set of processes and it's very difficult to figure out. I am a long term diabetic. I've been eating this way for years! It used to work great for me, but for about the past year or more, I am having trouble keeping it under control. I have recently started IF to try and get things in line but so far I"m having no luck. It really depends on so many things, how much insulin your pancreas is producing, how insulin resistant you are, how much your muscles are able to utilize, etc. The list just goes on on and on. I don't really have any answers for you. There are a lot of great doctors out there who can explain things way better than I can. Dr. Jason Fung seems to be a good one for information. Search him out. He has some books and videos on YouTube.
