Adam and Steve are best friends who do everything together -- work, play ... and eat. Unfortunately this last has gained them the nickname "The Rounder Brothers," something they are determined to change. Adam is certain he can beat Steve in the challenge to lose pounds, while Steve feels his wife and new house will be a great motivation for him to lose the most weight. The Fab Five hope to use the friends' competitiveness as they pit the two buddies against each other in the ultimate weight-loss contest.
