Except this entire narrative is thrown off by the fact that obesity has been a problem before any of that and is a problem in countries without any of that. Even places like Korea where you are literally shamed constantly by friends and family for being even remotely overweight has obesity growing all while having basically the exact opposite culture of what you are complaining about.
Basically the only developed country where overweight and obesity have stayed flat is Japan.
