Another low-cal academic study

Reading about dieting and weight loss may be harmful, a new University of Minnesota study of teenage girls has concluded.
OK, now what? How are the people who take the findings seriously - something that closer reading of the study suggests might not be a real good idea - supposed to react to them? What possible value is there in this study?
It found that middle school girls who frequently read dieting articles in magazines were twice as likely five years later to try extreme weight loss measures such as vomiting, fasting, smoking cigarettes or using laxatives.
According to one of the study's authors, Patricia van den Berg, the findings suggest parents should carefully consider whether they want their daughters reading about weight loss.
"It possibly would be helpful to teen girls if their mothers didn't have these types of magazines around," she said.
If the researchers used any public money to fund this study, taxpayers should get a refund.
