I do not agree to the statement. There are other reasons that lead to teenage obesity. Firstly, let me define the keywords of the question. Fast food means food that is prepared in quantity by a standardized method and can be dispensed quickly at inexpensive restaurants for eating there or elsewhere. In other words, food that is required little preparation before served. Obesity means the condition of being very fat or overweight.

Many of the television commercials seen by teenagers are for junk food products. According to research released this week by the American Journal of Preventive Medicine, this may be a major reason obesity rates continue to rise among 12-17 year-olds. The studies examined by researchers at the University of Illinois-Chicago and University of Michigan concluded that 26% of TV ads seen by teens were for food products. The vast majority of these products contain high amounts of fat, sugar and sodium.

Also, poorer and nonwhite neighborhoods also have fewer fruit and vegetable markets, bakeries, specialty stores, and natural food stores. Thus, those teens tend to eat more junk food than healthy food.

Teens also have few healthy choices at school. According to the research, many middle schools and high schools offer more unhealthy foods than nutritious foods, but not fast food. Many people believe schools carry a substantial burden of responsibility -- just behind parents and individuals -- when it comes to addressing childhood obesity. Many students fill up on items such as soft drinks, chips, and cookies, which are high in added sugars, fats, calories, and sodium, but low in nutrition. These 'junk food' are the main reasons to why fast food is not responsible for teenage obesity.

In my opinion, fast food plays only a small part on teenage obesity. It does not fully takes up the responsibility of teenage obesity. Other reasons are eating too much junk food and unhealthy food, and heredity problems. The mother of the teenager may have been obese before she had her child and this may lead to a high chance of her child being obese too.
