NBC's "The Biggest Loser" is introducing a pair of familiar faces to the competition: Richard Hatch, winner of "Survivor: Borneo," and Erin Willett, a Season 2 semifinalist on "The Voice," have joined the Season 17 cast of the weight-loss competition series, reported Us Weekly.

"This isn't me competing against any of them," said Hatch about his upcoming journey on the show. "Whoever loses the least amount of weight has done that themselves. I'm not involved, so my whole experience is focused on being above that goddamn line [for weight lost], that's it."

This upcoming season revolves around the theme "Temptation Nation," which is designed to help the contestants deal with real life temptations when it comes to losing weight, including money, food and electronic devices.

Luckily, Hatch isn't new to the reality TV. He was known on "Survivor" as the guy who almost always lacked clothing. Now 54 years old and 314 pounds, the reality star told told People that his desire for being naked hasn't changed much.

"I'm not an exhibitionist, but I don't care either, so I'm often naked. It's just the way it is," he said. "I don't give a crap about how people feel about how I look. But personally, I know that I'm fat."

As to why he decided to join the show, Hatch said he has body issues, which stem from experiences he had as a child, including being raped at the age of 8 and molested at 10. Hatch also revealed that when he was in the sixth grade, a prankster peed on his leg while he was in the shower.

"At some point, I decided what people thought of my body didn't matter," shared Hatch. "Most fat people I know say they don't want to be fat. That's a lie. If I didn't want to be fat, I wouldn't be fat. So, why do I want to be fat?"

He added, "I want to know why so I can see if there is something I can do about wanting something different — something better."

Unfortunately, Hatch, who is a father of three, suffers from high blood pressure and high cholesterol. "It's not about being able to lift this or do that," said Hatch. "It's, 'Is my blood pressure low again? Is my cholesterol level right?' That's where I'm headed now."
