Why is America so fat?

One of many problems with this country now a days is that America is fat. There is no nice way to put it Americans are fatter than any other culture in the world. I walk around all day and dont understand how people can be unhealthy. Health care is a big issue in this country, the problem is that we cant afford it. One of the main problems is that most americans dont have the knowlage, so if americans dont know how to be healthy and dont know why it is important then how can they be healthy. They cant! Most illnesses late in life can be prevented by just living a healthy life. This diesnt mean you have to be a bodybuilder or bikini modle, it just means to be aware of your body and how it can make your life easier or harder, even longer or shorter. The government isnt doing enough to control diet in schools, and even at resturants. Im not saying this is the answer to the health care problem but it is a start. It's your body and you only get one dont waste it.
