But you are a type two - unless your pancreas is failing due to long term over production of insulin, your beta cells are fine - it is your resistance to the insulin you need to alter.
This is not the scientific consensus.
Generally, by the time diabetes is diagnoses there is anywhere between 40% and 70% beta cell dysfunction whereas the insulin resistance has already reached a maximum.
The natural history of Type 2 Diabetes follows a course where insulin resistance 'compels' the beta cells to produce more insulin, and over the years the stress caused by this extra production causes gradual dysfunction. If it were the case that newly diagnosed diabetics only had insulin resistance then insulin production in OGTT would be at least as high as normal people but this tends not to be the case indicating the beta cell dysfunction. Also, postmortem studies have shown there is less beta cell mass: newly diagnosed T2Ds die too - perhaps of other causes.
However, what is important to understand, is that the exact form of this dysfunction and its extent is not fully known. Are the cells dead, unable to coordinate correctly, hampered by fat, dedifferentiation etc?
This last one, dedifferentiation, is interesting. Cells have evolved to preserve themselves. So beta cells it seems can turn into other cells, so there is a question of whether they can turn back into beta-cells again. A lot of research is ongoing in this area.
And of course, Rod Taylor's research suggests that beta-cell function is hampered by fat in the pancreas. Once again whether this can be reversed totally is not well understand hence his research.
But what is important is that there is strong evidence that beta-cell function can be improved. This is especially the case if you are newly diagnosed. Suppose for the sake of argument that you get your beta-cell function from 40% to 65% through weight loss, and then you combine this with exercise. You'll get a double benefit: your insulin sensitivity will improve, the exercise will reduce the need for insulin taking the pressure off the beta-cells. You can put yourself into a situation where you may not be cured but your blood sugar is essentially controlled. Plus you'll feel good about yourself and you'll generally be healthier anyway. How much your beta cells have actually recovered you won't know.
