I agree, When you explain it like this then it becomes clearer, and I was just concerned that Newbies may get the wrong ideas which is why I added the explanation since although I am a Low Carber myself, I do see the ND as viable especially for those not wanting the extra fuss of LC.
The point you make about the problems of follow through not being supported is valid, and of concern, since we do see reversals and needing to repeat the diet. It IS a diet in that it is time limited and not sustainable in long term, but I see it as a start to getting the NHS to consider using diet more robustly than it does at present. It is the first time I have seen the NHS admit to having a possible contender to bariatric surgery, which is their only cure mechanism to date. We should encourage this trial, since it may open the door to lifestyle changes such as LC being accepted at last. It is a stepping stone.
