People hear what they want to hear.
If I say; "you can eat your way to diabetes", some people hear "You're diabetic because you're fat", which isn't what I said or implied at all.
I think our environmental exposure from birth, or inherited genetics make us predisposed to developing diabetes; but it is all the choices we make (knowingly or unknowingly) along the way that determine if we will have diabetes T2......
If we can learn to look at being fat and/or diabetic as both symptoms of something bigger happening within us, then we can lose some defense mechanisms and work together to try and help each other.
A metabolic disorder is what we have......
It is human nature, to look for complicated solutions, even to simple problems. If the answer is too easy, we dismiss it, as it can't be that easy. But, sometimes simple answers are the best solutions.
Put simply; I am where I am today. What I did in the past got me here. What I do today will get me to where I am in the future. If I keep doing the same things I did in the past, I can only expect more of the same in the future. If I do something different today, then my future has a chance at changing.
There are two major things I must do if I'm diabetic and want to control it. Control my mouth and my activity. There are many other things we can do, but controlling our mouth and our activity are by far the things we can do that will give us the most benefit.
Woulda, shoulda, coulda is not going to change anything. Acceptance of "what is" and doing something NOW and not worrying about all the stuff that preceded as though a thorough understanding of genetics and human disgetive evolution is going to suddenly make things all go away...
Anyway, I hope I sounded controversial enough....
