"I'm super excited about taking the position of host on The Biggest Loser," Harper, 50, said in a statement. "I've been with the show since season 1, so I know all of the ins and outs, and let me tell you, the weigh-in room is going to be a completely different ballgame with me at the steering wheel."

Those who loved Harper as a trainer will be happy to know he'll still be involved in the contestants' weight-loss journey. According to the show, he will "offer his training expertise to contestants at various points throughout the season," and will also guide them along "through all weigh-ins, challenges and temptations."
