Somthing else that is causing americans to be so over wieght is the people that manufacture the food put things in it to addict people,like for instance if you do research on the beverage coke than you will find that they used to stick cocain in thier drinks then people would be addicted to there drink and they would sell a lot more of there product, then cocain got banned and now they use caffeen to addict people and that is a good portion of the reason that americans are becoming over wieght.
