Low carb treatment was the gold standard worldwide, BEFORE Insulin was discovered. It's been around far far longer than low calorie. We get caught up in supposed progress, forgetting what our ancestors learnt. You keep banging on that ONLY low calorie can improve the Pancreatic function. The truth is, nobody has studied properly the effects of low carb, because there is no money to be made out of it. Virtually all modern medical research programs have a specific aim, which is rarely the headline that it's published under. But always with an angle of huge INCOME!
The vast majority is funded by Pharmaceutical companies, who are not interested in curing anything, just the next must have lifelong drug therapy. KERCHINGGGGGG.
The low calorie short sharp shock treatment does work, but it is itself actually low carb. The major problem is the patients don't learn what is good for them to eat, so the few that can actually last the course, afterwards are back at square one, albeit lighter in weight. And as soon as they start eating a normal diet, ie what gave them diabetes in the first place, we all know where that's heading. Still as so many have to, they can always have another go.
As you are maintaining your remission and weight i applaud you, BUT you are very much in the minority. As the study showed VERY few can actually last the course, and remain in remission, you are one of the lucky ones.
