"Study: When kids become teens, they get sluggish," by LINDSEY TANNER, AP Medical Writer (warning, contains fearmongering)
While 90 percent of 9-year-olds get a couple of hours of exercise most days, fewer than 3 percent of 15-year-olds do. ...
The ... study, appearing in Wednesday's Journal of the American Medical Association, tracked about 1,000 U.S. children at various ages, from 2000 until 2006. ...
I've seen a few critical comments on this study along the lines of "Teens have more responsibilities," "Schools make children hate exercise," and so on. But what I'm wondering is — if somewhere between 10 and 15 is the magic cut-off point where children become less active, has anyone asked whether there might be a biological cause, something to do with puberty? Perhaps the body says to itself (via hormones) “We have to save some of this energy for reproduction now.”

I wouldn't use the word "overweight" to describe the body of a healthy pregnant woman. If that's "overweight," then the definition of "not overweight" is messed up.

Also, the study shows this happens to teenage boys as well as teenage girls.
