Cause Texas doesn't have any pork bbq w/ vinegar sauce. Everything is beef brisket here......dammit.
Seriously though, moved to Houston from Charlotte in 2005.....Houston I think just won the fattest city in the US that year. A commuter city, too many restaurants, not just just fast food & taco trucks. There is a hugh variety here and the plates are full of food. Serving sizes definitely an issue. But poverty + cultural are the big hitters....AND combined with SUGAR & PROCESSED FOODS...tada.....fattys.
...and Mexico just took the top fatty spot from the US. Which is weird, didn't see many fat people in GDL when I practically lived there for a few months tranferring production lines from Charlotte to GDL.
I think the US has exported the processed food/sugar
