I think it's just simply that Americans in general consume more calories and are less active. I mean, what other reasonable explanation is there, considering the number of fat Asian-Americans and skinny white Europeans. Sure there are some Japanese big eaters, but after observing people in Japan, that doesn't seem like the norm here. The portions at most resturants in Japan are pretty modest by American standards. And Americans take their cars everywhere. In Japan, even in suburban areas, far more people walk, bike, or take public transportation (taking the train might not seem like a major fat-burner, but subways usually involve lots of stairs, and trying not to fall down during rush hour probably burns more calories than sitting in a car).
Also, you can observe the same phenomenon just within the US. Compare how many fat people there are in the Midwest to NYC, where people walk more and there aren't as many of the typical American franchise resutants with supersize portions.
