The worst part of the nakedness on Discovery Channel‘s Naked And Afraid? Bare feet, according to four alums who showed up at TCA Summer TV Press Tour 2014 to plug the show’s new season.

2014 Summer TCA Tour - Day 2“Being barefoot was one of the worst parts about being [naked] for me,” said Jeff Zausch. Dani Julien said the most important prep she did for her 21 days without shelter, clothing, food or water was to walk around barefoot in the days leading up to her TV debut.

One critic wondered how the four former show participants on stage would rate the quality of the pixilation of their various body parts. “They could have made my blur spot bigger,” Justin Bullard complained.

Naked And Afraid has a team of six special-effects artists, who go through each episode, frame by frame, to create the proper amount of pixilation, said exec producer Jay Renfroe. “And Justin is right — a lot of guys do request larger blurs.”

Naturally, panelists got asked if the “Naked” part of the show is exploitation. Naturally, the exec producers responded they never saw the nakedness as exploitation. They talked about Adam and Eve; they quoted the Bible. “This is a family show and families all around the world are watching. It’s not about the nudity; it’s about the survival,” said exec producer David Garfinkle.

Clothing, they explained, is “the ultimate shelter,” said Julien. “Without clothing you can die in some situations within minutes. Clothing protects you from bugs, from the sun. Stripping that away adds another element to the survival challenge.”

“There’s a psychological element,” added EP Steve Rankin. “People feel incredibly vulnerable.”

“It fit on Discovery, because we’ve been doing survival shows for years,” added Discovery Group President Eileen O’Neill.

In Discovery’s survival series, a new pair of strangers each episode will find themselves stranded in some of the world’s harshest environments with no food, no water, no tools…and no clothes. As their extreme survival skills are put to the test for 21 days, each couple must battle the elements, each other and their own inner weakness to triumph over the terrain and their predicament.
