Thank you. What about this selection of a comment by the author of the article:
"I’m presuming you’ve read Steve Cooksey? He is an example of a perfectly controlled T2 diabetic, drug free. He is fully healthy (as far as any of us can tell), but he can’t eat pizza after years of LCHF. Something changes permanently…"
So it causes chronic prediabetic blood sugar and may be irreversible. This sounds like a serious concern.
This comment conversation is also noteworthy:
I don’t know whether this post is still active. I was doing ultra low carb for 5 months (30 grams or less a day). During that time I had a FBG of 96 on a random test which gave me concern, as I’m usually in the low 80s. I quit doing ultra low carb over 3 months ago, and my fasting blood glucose is now 100-118. Post-prandial has gone as high as 162. So have I permanently made myself diabetic by this low carb diet? I would think that 3 months after going back to a more balanced diet, my glucose levels would have recovered.

I was on an ultra low carb (ULC) diet for 5 months. A random blood test showed fasting blood glucose (FBG) at 96, which concerned me, as I’m usually in the low '80s. Since then, I have quit the ULC diet. I’ve been eating moderate carbs for 3 months now. Yet my FBG is now 100-120 and post-prandial can get as high as 162. Have I given myself diabetes from this ULC diet? It seems it is not reversing itself once I stopped ULC. I’m very worried that I’ve impaired my ability to eat carbs permanently.

I think it is quite clear that there is zero evidence base for your having given yourself diabetes by carbohydrate restriction. The physiology is quite straight forwards, I see no reason why it should happen.
There are a stack of unknowns about your circumstances. I would be very concerned about a BG over 160mg/dl post prandially and would do whatever was needed to stop it going there. You have only two tools, LC and drugs. You need to know if you need drugs. You do need LC, on the most simplistic of generic observations…
Peter states that there is zero evidence that carbohydrate restriction can give someone diabetes. However in his article he states that one would fail a glucose tolerance test and would be diagnosed diabetic and that his fasting glucose is pre diabetic. The in the above, first comment by peter, he states that “something changes permanently” and if this “something” is a permanent insulin resistance which would presumably cause permanent high blood sugar, isn’t that very close to diabetes caused by carbohydrate restriction?
Finally, don’t prediabetic blood sugar levels and a diabetic response to a glucose tolerance test strongly contradict LC and keto improving insulin sensitivity and reversing diabetes since these are symptoms of impaired insulin sensitivity and diabetes?
One more thing, this directly contradicts the idea that LC and keto are fantastic for improving insulin sensitivity:
From the article:“Well, the first thing is that LC eating rapidly induces insulin resistance.”
I am so lost. This is the opposite of everything I have learned about keto!
