Why does curing type 2 diabetes remain a secret?

I find it shocking that, as easy as type 2 diabetes is to reverse, backed up by even human clinical trials validating this concept, few doctors inform their diabetic patients of this. Oddly, now that GLP-1 agonist (disastrous) drugs are available, the reduction in blood sugar coupled with weight loss has brought the idea of type 2 diabetes remission to the forefront, since it now is profitable to reverse it. But you do NOT need any pharmaceutical to reverse type 2 diabetes...
