If I can make an observation....
If only Taylor and Co opened by saying that there are many possible reasons for poor automated blood glucose control other than autoimmune destruction of the cells that produce insulin in the pancreas and these come under the umbrella term of T2 diabetes, then that would help.
What they have shown, and shown convincingly, is that excess fat around the liver and pancreas accounts for poor blood glucose control in a significant number of those with a T2 label and taking measures to reduce that fat in those affected is a very effective method of restoring blood glucose control. They tend to make no reference to those with a T2 diagnosis who are not overweight, indeed if I recall correctly they exclude such people from their studies. The way they report things tends, at least in my view, to make it easy to assume that getting rid of non-T1 diabetes only requires losing a bit of fat. That may be the case for a major subset of those with a T2 diagnosis but does not apply to all.
My take on all this is that if you have a T2 diagnosis and you are overweight then loosing that excess weight offers a very good chance of regaining automatic blood glucose control. I prefer the language of risk and uncertainty rather than the implied positivity in Taylor's (other gurus are available) reporting.
As you might guess I am one of those for whom it does not work. T2 label but not overweight, who's auto blood glucose control would be of concern if I did not take some pills and deliberately control my carbohydrate intake. I accept I am in a minority but I suspect I am far from alone.
