Let me put this a bit differently: Type 2 diabetes is both genetic and can be acquired during one's life (e.g. through bad dietary choices). But a man who develops diabetes does not acquire genetic T2D by doing so - he cannot pass it on directly to his children.

Epigenetic changes absolutely can be passed to children even over multiple generations--this is already proven.

Which epigenetic changes are caused by T2D and whether they predispose the next generation to T2D would be the question.

You could get a Nobel prize or two by proving this statement.

How we pass on acquired traits to offspring is not well understood at all. We know there’s a mechanism, but not how it works or how selective it is.
