Entertainment TV What Celebrities Will Be Joining 'The Biggest Loser' as Contestants This Season? Dr. Robert Huzienga hints at some surprise star power By Matthew Cole Weiss Published on September 14, 2015 10:20 AM Share Tweet Pin Email Photo: Paul Archuleta/FilmMagic Though there have been rumors of an all-celebrity version of The Biggest Loser for years, the show’s on-camera medical consultant, Dr. Robert Huzienga, says a couple familiar faces will definitely be popping up on the weight-loss show’s upcoming 17th season. “We have two celebrity additions,” Huzienga (known on the show as “Dr. H”) told PEOPLE exclusively at The Brent Shapiro Foundation Summer Spectacular in Beverly Hills on Saturday. “I’ll probably get chastised by NBC publicity, but we have two nugget surprises in there.” Filming began last week, but Huzienga, who is also an associate professor of clinical medicine at the University of California, Los Angeles, can’t reveal the identity of these celebrities. However, he promised the stars are just as in it to win it as everyone else. “I can’t tell you who, but a lot of sweat is coming from them this season,” Huzienga said. This won’t be the first time a famous face joined the cast: American Idol winner Ruben Studdard competed show back in 2014 and lost 119 lbs.

It makes sense that the show would try to add some star power considering the recent departure of host Alison Sweeney (who will be replaced by trainer Bob Harper). “After 17 seasons, Bob and I are the only people in front or behind the camera remaining human beings associated with the show,” Huzienga said. “It’s amazing how TV changes year to year. They’ve got to get a different look. We have a couple different surprises. It will be interesting.” So how is Harper doing so far? “Bob is kicking butt,” Huzienga said. “He’s a fish in water. I’m proud of him.”
