If im wrong about it then why do so many people shame American women for being fat?

I always hear people say they want the Asian waifu because they aren't fat unlike the American women, but wouldn't that imply its the American women's fault for eating too much?

But people say that its not because Americans eat too much its because the food in America is unhealthy. And if that's the logic then how can we attack and blame the American woman for being fat if its not the American woman's fault, that the food in America is unhealthy ?
