Except that what a pregnant woman eats also affects her unborn girls eggs. You might be able to lay some blame on you mother and even your grandmother if you are insulin resistant.
Insulin sensitivity is going to start being determined from the moment the sperm combines with the egg. If your mother, while you were in the womb was eating a high carbohydrate diet which is turning into sugar, we have been able to show that the fetus in animals becomes more insulin resistant. Worse yet, we are able to use sophisticated measurements, and if that fetus happens to be a female, they find that the eggs of that fetus are more insulin resistant.
So we may have to go back further than just the visibility of the symptoms and it might just be that the bad stuff is showing up sooner - ie. Pottenger's Cats.
It's quite common to see families with illnesses happening about 20 years sooner every passing generation. Grandparents with got them in their 70s-80s, parents in their 50s-60s, and now children in their 30s-40s.
I know a few families like this where three generations have had heart attacks, roughly 20 years earlier each generation.
I have lost a few friends to heart attacks and cancer in their 20's and 30's and my dad's heart surgeon has quit his job because he is so disheartened at seeing people come to him younger and younger each year.
My wife and I don't just eat strict paleo for ourselves, we do it for our kids and grandchildren too.
