Story about two friends one fit one fat

[Craiger16]

One roomate says she will lose weight but for every pound she loses her fit friend has to gain it.

Towards the end the formally fat girl is now very fit and the other is pretty large and wants to lose weight but the fit friends desides not to help her.

Any ideas would be appreciated.
