When I was DX'ed some 30 years ago, the NICE advice then was simply to cut out sugars and starchy foods, and LOSE WEIGHT. Later on the Meditrrranean Diet was included in the advice since it was successful in reducing those very items off the menu and showed a reasonable but significant treatment option.
So ND is simply a re-packaging of that advice in a simple to follow turnkey plan. It is the same plan as was being offered by the likes of Slimfast, Optifast, Exante, Cambridge Diet Plan, Huel and many other vendors. These same suppliers have all featured in the ND plan. What is significant is that these same diets are on sale today, but I rarely see any mention of them here in the Forum and they are not commonly referred to in the success Stories/testimonials thread either. They only claim that their products may be useful in reducing blood sugar, but they make no claims to give remission as far as I have seen. so we have a marketing strategy by ND to hook T2D into thinking this is the answer to a maidens prayer. It is a useful tool, but not a miracle cure. It is over hyped for a start. some of the claims do not hold up to scientific scrutiny, and as I have found out they are based on some dodgy maths.
I note that the Fast 800 Plan from Michael Mosely is actually marketed as a low carb diet using the same meal replacement therapy.
When ND published their findings from DIRECT trial, Roy Taylor was very specific that it was necessary to lose 15 kg weight to get to remission. This new article seems to defy the great Professor. Fair do's. I was never convinced that it was that simple anyway. But it sells product.
