exactly ! it's not about the food , it's about the quantity of food . sometimes i even wonder how thin people do to remain thin in America !! you eat WAY too much . there's butter in almost all my meals , but the portions are small . I do sport because i like it , initially it's not to maintain my weight ( well  except for that time when i HAD to lose weight) it's something I do just to get the endorphine , it feels good . weight is all about the amount of food . not everyone gain weight at the same pace , so that explains why you guys have so many fat people .
