Sorry, I should have clarified that my implied frame of reference was the US. But you're right. There seems to be a pretty linear correlation between obesity rates and the "American way of life," however we want to quantify its variables: processed foods, sleep deprivation, etc. Generally speaking, the pursuit of convenience at the cost of all other considerations.

And I don't deny that processed foods are major factors in the obesity problem, and probably necessary factors. But I'm saying that they don't seem entirely sufficient to account for the increased obesity rates within the US, which has been gorging itself on processed junk for 30+ years now.
