That is true in Thailand as well. All the big fast food franchises are here and many people love them. To me, they smell almost as bad as they did in the states - but some additives are not allowed here, so they are marginally "less bad." Many of the older people regret they are here, but the younger people flock to them. Obesity is rising in Thailand as well - but not the the extent as in the west. I can see it rising, even as the people are generally much healthier. Like you mention, it is really sad to see since we know the result in the us where it all started.
