If you thought you'd seen the last of Richard Hatch, think again: The original Survivor is back to stir things up on The Biggest Loser.

After winning big on Survivor, the 54-year-old hopes to lose big on the NBC weight-loss competition show, and his weight struggle comes with a unique perspective.

"I'm dying to learn why I want to be fat," Hatch says. "I wouldn't be fat if I didn't want to be fat, so clearly I want to be fat. That's my journey. That's why I'm here."

Hatch is entering The Biggest Loser at 314 pounds and aims to slim down to 225 pounds, but he's not the only reality star competing this season. The Voice contestant Erin Willett is also in the running. The singer, who competed on season two of The Voice, revealed that the death of her father was a major contributor to her weight gain.

"I struggled with bulimia and was just very disgusted with myself that I had gone to these lengths," Willet says. "As much as being fat kills your body, that also kills your body, and I didn't know how to control my life for anything."

The show's 17th season will carry the theme of "temptation," and will incorporate non-food indulgences such as shopping and using electronic devices.

Trainer/host Bob Harper insists that while they've switched things up a bit this season, there are still a few key things that will remain the same.

"Even in the first episode you're going to see me yelling at people on treadmills, which I feel very comfortable doing," Harper says with a laugh.

The Biggest Loser returns to NBC on Jan. 4 at 9 p.m.ET/PT.
