I was just quoting from my medical book, that seemed to reflect on what I was seeing myself( it was a very confusing and worrying time 12 months ago).
Yes, I fully agree that everyone is different and I can only speak from my experience, and what I've learnt over the past year.
My fasting blood sugar from the lab results was only 6.5(pre-diabetic) and not yet at diabetic levels at the time, but my hba1c was taken too soon after the infection and ended up being higher due to a bad UTI(that I've been having since birth), and maybe the reason I could reverse so quickly my condition. But it did take big changes like cardio every day, and being very strict on myself even over Christmas with cutting carbs and ended up losing 40kg(88pounds) in a very short time. The biggest thing that help me was my Apple Watch, I could see how much exercise I was getting, and set targets for each day, so to stop me from being lazy.
This summer I went on a 3 week full-board holiday, and was very nervous as I expected to return to pre-diabetic levels after pigging myself on all that food and even cake, and my fasting to jump up to 6s again, when I got back home, but I was shocked at 5.0 after a long drive home, and next morning 4.5, and 2 hours after breakfast 4.8. But even so, I continue to monitor and be very careful with carbs between 130-160 per day, so I don't stress my body and put weight back on.
I hope my experience will be of help and encouragement to others.
