At 5'4" and 290 pounds, 46-year-old registered nurse and mother of three Trina is afraid she'll soon become one of the morbidly obese patients she cares for in her hospital. She often calls herself a hypocrite for insisting her patients get their weight to manageable levels, while she continues to neglect her own growing obesity. Trina hits the ground running in the first month, really embracing her new lifestyle. She even gets the group of nurses from her hospital together for a special workout, hoping to show them all the amazing things Chris taught her at boot camp. Chris is so proud of her, he sends a fellow fitness guru, Richard Simmons, to inspire and motivate the nurses. Unfortunately for Trina, the amazing rush of losing weight and working out with one of her fitness idols is quickly lost when she and her mother resume their co-dependent relationship, which sends her back into her bad habits. Trina's husband, Eric, contacts Chris and tells him that he needs to get out to Michigan right away to help save his wife from herself. For the first time, a participant actually gains weight.
