Zombie - Don't start going all radical straight away or you'll find yourself with very little to enjoy. Obviously, avoid the big boys; the frank sugar and heavy carbs, and get yourself into a testing and food recording routine for a week or so. Then, you will have a little data to go on. If, like me, you only have a couple of things you routinely have for breakfast, say, you can look back over your diary and bloods and see if there are any real stand out no-nos. Then deal with those, and take it from there.
But, don't forget, that you will see a rise when you eat - unless your meal is really very fat based, with no carbs whatsoever,but, for most of us, going that far isn't altogether necessary.
I don't know if you have any poundage to drop, but if you have, as that happens, not only should your bloods improve, but it is likely your tolerance to carbs may increase too. So, it could be that something you have to limit quite a bit now, could actually be reviewed in due course.
In my view, it's better to take an incremental approach and understand why you are limiting or eliminating certain foods; rather than apply a broad brush stroke approach only to unknowingly have eliminated a perfectly benign food or drink. That's the problem with this condition being so personal.
Keep up your good work. If enthusiasm alone could crack this thing, you'd have done it already.
