Obesity (not overweight) is 33% in the US and 29.7% in Argentina.
I have eyes. Also factbooks which are more impartial. Sadly, go outside Cap and you will see PLENTY of overweight people. Looking at people in Buenos Aires and extrapolating that to the population of Argentina is like talking about the population of NYC and using that as your basis for talking about the US. Hardly representative of the entire country. Hell, I live 40 minutes from downtown and most of the people I see around here are overweight. Yes, the US definitely has more extreme obesity than here but no shortage of obesity here.
(FWIW, I totally agree natural is always better. Just pointing out that the diet of fried food, ice cream and pan has consequences as well).
