Shedding for the Wedding

This week the couples get to choose their wedding flowers, but in order to win them they must power through a grueling wedding challenge on the beach. In addition to the flowers, winning the challenge also earns one lucky couple a one-pound penalty to be given away to another couple at the weekly weigh-in. Also, after failing to lose any weight the previous week, two contestants receive special attention from nutritionist Ashley Koff, R.D. Finally, two couples face off in the final eliminate challenge and one couple will be sent home.
