Rates of type 2 diabetes are in the non-overweight population are extremely low.

Skinny people can get type 1 diabetes, but that's a completely different disease -- acquired hypoinsulinaemia, as opposed to hyperlipedaemia. (Note, neither diabetes is essentially about glucose; it just happens that hyperglycaemia is a symptom of both diseases, and Aretaeus didn't know better.)

The only point I'm trying to make is that blood sugar is culprit of the numerous conditions afflicting wealthy countries, not just obesity. Clearly obesity isn't a neutral variable in this equation.

And my point is that (aside from glycation damage), blood sugar is a symptom of disease, not a cause of disease.

If only we could figure out a way to not eat foods that increase the amount of sugar in our blood....
