Probably:

"Middle school girls who are more physically active have a lower percentage of body fat than their counterparts with lower activity levels, according to new study findings."

Probably not:

"'An additional 11 minutes of brisk walking or similar activity as girls age from the sixth to eighth grade appears to attenuate increased body fat,' lead author Dr. June Stevens told Reuters Health."
