First, @Raithe I'm also very sorry to read this, and all the best to your father.
That was pretty much my experience as well, however, I've never been at the point where I had to inject insulin. I'm still taking my medication, but I am fairly certain that I don't need it. I get the same blood sugar levels if I leave it out, however, as it's not designed to lower blood sugar but simply stabilize it by retarding my body's ability to store carbs for later use I still take it regularily. It works as potential buffer for the days where I don't really feel like sticking to my dietary regimen*.
Which brings me to the next point. It does work really well, and it kicks off with this nice sense of euphoria that you're currently experiencing. I'm not trying to rain on your parade there, but that feeling levels out eventually. The need to just stuff everything in your face you run across just might come back. It did for me. However, chances are that it won't nearly be as problematic as before, but it's something you might want to take into consideration regardless (I deal with it mostly by physically seperating myself from food sources, which was a lot harder to do during the lockdonws).
*By that I mostly mean watching calories for dinner, which is my second meal. I can't for the life of me eat anything after getting up, so it's lunch and dinner, with the occassional smallish snack in the form of berries, an apple or something like that in between. Although I try to avoid high sugar fruit when possible, so it's not a lot of apples or bananas. On a day I don't feel like it, I'm still sticking to the intermittant 8:16 fasting regimen, I'll just either exceed my set limit of not eating any more than 400 kcal for dinner mostly (or exclusively, at times) in the form of proteins or just drop the healthy snack thing in lieu of stuffing my face with ice cream or my usual go-to sugar source of gummibears.
You cut out the source of your chronic inflammation of your small intestine which prevented the normal absorption of nutrients. Getting to a healthy weight and stabilizing blood sugar kind of comes with that, so nah, that's not a seemingly weird result of eating more healthy, but a perfectly normal and logical one. Eating healthy just means something entirely different for you than for most people, and that sucks.
Rhetoric caveat:
's mostly hokum, as your stomach acid readily kills the bacteria present in any "probiotic" food, and you're left with what's mostly too expensive yoghurt and not enough bacteria that survive to make any real difference. There's one thing consuming yoghurt (or any other supplements containing the usual lactobacillus bacteria) can help you with, and that's preventing or easing side effects of having to take antibiotics - and for that eating your good old regular yoghurt usually does the trick too (and is cheaper). Seems sort of logical too, what little of the bacteria survive being broken apart in aggressive acid can make more of a difference if you kill large swathes of your gut flora along with whatever disease you have in your body.
If you want to improve your gut flora, there's only one efficent way to do that, and that's getting a fecal microbiota transplant, and yes, that's exactly what it sounds like.
