Hi ickihun, thank you for your words and tips!
Insulin was de-prescribed after good advances fasting blood glucose, HbA1c, and fasting insulin. I do a (very) low carb diet but with a lot of cheating episodes. At least one / weeek.
But something very curious happend.
I needed to do a travel vacation with my family and I was very scared about to fit in the airplane seat, to fit in the airplane belt seat, to keep acceptable blood pressure numbers, as well as good blood sugar numbers (both fast and post-prandial).
To avoid any bad surprises, I behaved like a monk during all the trip, with one meal a day (or two), strict ketogenic, no alcohol. And, after a week I produced these interesting results, as well as good blood pressure numbers, and could fit inside the airplane seat (and the belt).
But...
Returning home, new year celebrations, my aniversary at jan 7, etc, I did return to the old 'chetogenic' lifestyle. And, obviously, lost all the progress.
These two scenarios were a very important lesson for me, because I know I am capable to handle my condition, I could address it in the past, and befor the trip I was thinking that was the time needed to look for some help (Ozempic, os something like this). But this strict period showed me that my body is still responsive. It is just a matter of mindset.
