A sea change in the world's treatment of T2 which reverses T2 for tens of thousands cannot be kept secret in case it doesn't apply to some who can't lose weight. Or indeed to those who have had T2 for more than 6-10 years. Not all treatments for other conditions, eg cancer, work for everyone. That is not a reason to withold treatment from those who can benefit from it.
Who is advocating holding back treatment? Who is trying to keep this a secret? You are over dramatising one aspect of diabetes care. Please be more moderate and considerate.
We query the explanations being offered up for one diet. I did the same for LCHF. It is important that we review so called science when it is a theory only, and making statements about beta cell demise is questionable. Not all mechanisms have been researched yet, and the cause remains unproven. This does not stop the NHS using this method as a treatment, or prevent us from recommending it here in the forum. As i have stated many times I believe the treatment to be effective for some. But it is one of many different paths to the required outcome.
You seem to be obsssed with only the weight loss aspect. I consider the adipocyte fat removal by whatever method to be the key. It is a fact that the diet shakes used by Taylor et al were both Low Cal
AND low Carb, so even the diet explanation is open to question.
