Sweeney, 48, and Harper, 59, opened up about how much they disliked the NBC reality show's temptation challenges in Netflix's new three-part docuseriesFit for TV: The Reality of The Biggest Loser, which premiered Friday, Aug. 15. In the challenge, contestants were encouraged to quickly eat a large amount of unhealthy food in exchange for a chance to visit with their families during the week. This was despite the show's stated goal of being focused on weight loss. The contestant who consumed the most calories won the challenge. "The temptation challenges were the hardest part of the show for me," Sweeney says in the docuseries. Courtesy of Netflix "There was a challenge where if we eat enough food, we win a prize," season 7 contestant Joelle Gwynn recalls. The contestants would still be weighed later and needed to lose weight, but whoever consumed the most calories from the junk food buffet during the temptation challenge, in which they were left alone with the food for five minutes, had an opportunity to go home and visit their family, with their trainer in tow. https://people-app.onelink.me/HNIa/kz7l4cuf "That's mean," Gwynn says. "We go through enough s---, we go through enough stuff. We're trying to do better." "If I just eat this slice of pizza, is that going to be enough so I can go home and give my boys a hug and tell them that I miss them?" another contestant says. Harper said he was not a fan of the challenge either, and called outThe Biggest Loser'sproducers for including it. "There'd be just like, all this stupid s---," Harper says of the challenges. "Candy, cake, cookies, pop — anything. All the things." "It was so dumb to me," he continued. "Well, thank [The Biggest Loserproducers] Dave Broome and JD Roth. I mean, it was their show."

For their part, the producers argued that temptations are part of reality and needed to be mirrored in the show in some capacity. "What is a temptation? A temptation is real life," Roth, one of the show's executive producers, says in the docuseries. "I can't say 100% of the temptations we got right. But I can say that life is full of temptations." "I needed the show to be relatable to the rest of the world who aren't in this dome that we've created," Broome adds. "You pass a cupcake in your refrigerator or on your counter or you pass that fast food store or restaurant on your way home from work. How can we get that inThe Biggest Loser?"
