Thanks for the detailed reply. I figured it was just more carbophobia blah, blah, blah.

High fat diets on the other hand do produce higher and higher levels of insulin AND carb consumption has actually started to decline in the recent decade yet we're still getting fatter so those calories are coming from fat:
