Katie and Tim's journey towards a healthy lifestyle won't come easy. Tim suffered a head injury 12 years ago that has left him with diminished use of the right side of his body, and Katie has chosen a wedding dress that's several sizes too small - as a way to encourage herself to drop the weight. Both hope this challenge will result in a deeper partnership for their life ahead.

Both former college athletes, Alex and Jordan are having trouble adjusting to post-collegiate life. While the fun-loving, engaged couple's workout regime and active lifestyle have diminished, their unhealthy eating habits haven't. Hoping to embrace health-oriented living as newlyweds, Alex and Jordan are dropping everything to shed the pounds before they walk down the aisle.
