The Biggest Loser Unveils Its Biggest Challenge Yet

NBC's hit weight loss competition starts back up with its ninth season and heaviest participant yet

Fans of The Biggest Loser, the weight is over! NBC's heavy-hitting reality series starts back up tonight with its largest contestant ever.

(So don't let that bit of holiday weight you're carrying bum you out: You've probably got a ways to go before you'd be able to compete with season nine's contestants.)

This season's couples consist of moms, daughters, brothers, grandparents and grandkids. Then there's Michael, one-half of a mother and son team, who weighs in at more than 500 pounds, the heaviest participant in Biggest Loser history.

Which couples are you rooting for, and who do you think will see the biggest weight loss this season?
