I think this is the post you're referring to, scandichic:

And here's one of the Swedish studies:

I'm not sure anyone reads links that people put on here. In case you can't be ***** (I generally don't read links people put up), 100% of adherent patients had an hba1c in the 6s
and reduced their insulin dose. You will struggle to see a stronger efficacy signal.
We can argue over studies until we're blue in the face, but the regrettable fact is that the most important efficacy signal is patient experience, which is generally ignored by the NHS at large, and by certain members of this forum who persist in arguing against it. Why can't people accept that eating fewer things that raise your sugar levels, gives you better sugar levels? Paradoxical, to say the least.
I feel like I spend most of my time on here defending low carbing. It would be nice if we could get back to supporting each others' daily grind with diabetes.
