It once was called the "Freshman 15." Now it's the "Freshmen 5" -- 15 was apparently an inflated number -- and even though the tendency for young women to gain five pounds after embarking on a new college experience doesn't seem so devastating, it's still quite alarming, say Canadian researchers.

It's alarming because the weight is typically gained over six or seven months. Putting on weight at this rate can be very problematic.

While there are limitations to the study of this phenomenon -- women who took part in weight-gain research reported only what they ate during the prior 24 hours, for example -- it's clear that colleges need to do more to incorporate physical activity into the lives of female students. And girls entering college should be advised to eat right and exercise well.
