Can One Man Curb Teens' Fast-Food Obsession?

A burger, medium fries and a shake contains approximately 2,000 calories and 100 grams of fat, more than what a teen should consume all day.

A study by the Boston Children's Hospital shows teenagers who regularly eat fast food gain an extra 6 pounds every year, and the health implications are grim.

According to a medical study, one in three American children born in the year 2000 will develop type 2 diabetes due to poor diet.

"I would argue that the price of fast food is an illusion," Schlosser said. "I mean, it may seem cheap when you buy it, but the Dollar Menu doesn't include the cost of dialysis, which comes later.

"I think it is possible to have fast-food chains that are serving healthy food. And I'm not trying to put these companies out of business. I'm trying to change how they do business."
