Cathy Skel is one of the contestants of the second season of The Biggest Loser: Couples. She is a title sales closing agent for a real estate firm, currently based in Shiocton, WI. She is very young at heart, and despite her weight, she tries her hardest to keep an active lifestyle. However, her weight problem has ballooned over the past decade, and when both her parents were hospitalized due to heart conditions, she became more compelled to lose her weight, if only to prevent her from suffering the same fate.
She joined the show with her daughter, Kristen Steede, and was part of the Purple Team, under Bob Harper. Currently, she is part of the Blue Team, still under Harper.
