Diet Worldwide, adolescent obesity is increasing. Parental responses differ, from indifference to major focus. For some U.S. parents the response is to spend thousands of dollars trying to change their children, as is the case for the parents of these girls eating breakfast at Wellspring, a California boarding school for overweight teenagers which costs $6,250 a month. Every day, these girls exercise more than 10,000 steps (tracked with a pedometer) and eat less than 20 grams of fat (normal is more than 60 grams).
