Main problem of americans is they eat not healthy and walk only from car to office and home and toilet, that's pretty much all distance they make on average in their life. When I used to live in USA, I was weighting 185 pounds wit hhealthy life style, but american food. After i came back home now i weight 163 pounds, my height is 5.9'.
