Can I make
one tiny suggestion? This is all very overwhelming, and you're getting a LOT of advice, and most of it is contradictory, I'm sure. From professionals, friends, family, strangers on the internet... So here's my last 2 cents, and then I'll leave you be.
Honest!
You can experiment. You have a meter. It won't try to sell you on one diet or another, some dogma, won't try to get you a subscription or make you buy books or whatever. It'll just tell you what your blood sugars are. I know that if I have breakfast with just 3 eggs, some bacon and grated cheese, mug of tea on the side, my blood sugars won't go up more than maybe 1.0 mmol/l in 2 hours and come right back down. I stay within the 4.5 and 6.0 range all day. I got my numbers down in weeks, not months or years... (Also solved my non alcoholic fatty liver, high cholesterol and a bunch of other things.) And I've been in the normal range ever since, going into my 4th year now. Took me 3 months to figure it out completely and satisfactory because I was experimenting a lot, but the differences were instantaneous. Why did I do that? Because I was inundated with loads of contradictory advice, was on medication that made me severely ill, and when I experimented, my meter told me that eggs with the trimmings were a lot better for me that cereal, for instance. (That would make me see double digits. Forget my usual lunch buns!). There's no pressure, no judgement, and no chiding from a meter. It'll just tell you what's what.
So there it is. The usual advice is to aim for a rise of no more than 2.0 mmol/l between before the meal and 2 hours after the first bite. I find it an excellent rule of thumb to go by.
Completely up to you though... If you're happy with the progress you're making, fine... But you could be doing a whole lot better. If you want to. It's scary and overwhelming so i do understand if it's all a bridge too far. Just hope you know, you have options yet.
That's all.
