WENN 1 / 6

Another day, another "Biggest Loser" scandal.

Over the long course of the NBC show, there has been no shortage of public outcry or former contestants speaking out against the TV mainstay. Earlier this month a report came out saying contestants often regain all the weight back because their metabolism never recovers.

The show producers and some of the trainers have argued against that.

Now, though, another former contestant has leveled sensational accusations against the show, saying that she was encouraged to take drugs to lose weight.

Joelle Gwynn, who was in the show in 2008, told the New York Post, "Bob Harper was my trainer ... He goes away and his assistant comes in. He's got this brown paper bag that's bundled up. He says, 'Take this drug, it'll really help you.'"

"I felt jittery and hyper," she said, claiming to only take a pill once. "I went and told the sports medicine guy. The next day, [the show's resident doctor, Robert Huizenga] gave us some lame explanation of why they got added to our regimen and that it was up to us to take them ... People chastise Bill Cosby for allegedly offering meds to women, but it's acceptable to do to fat people to make them lose weight. I feel like we got raped, too."

The NBC reality show knows how to combat sensational claims, as it's been doing it for years. Check four of the other biggest scandals that the show has dealt with over the years.

1. In 2014, Rachel Frederickson smiled while taking the stage to show off her 155-pounds weight loss. Her joy was overshadowed by harsh critics. Many feared that she had developed an eating disorder and that the show had essentially created an unhealthy competition. It was rumored that Jillian Michaels even quit the show in large part to Rachel's weight loss.

2. Last year, Season 2's Suzanne Mendonca told Globe magazine, "I was eating baby food. I'd wrap myself in garbage bags to sweat. We would use the sauna for six hours a day. People were passing out in the doctor's office."

3. Rulon Gardner, Season 11 contestant and former Olympian, was so against the show that he didn't attend the finale of the season that he was on. He later said that not only did the producers and trainers force him to keep working out after he had a serious neck injury, but according to him the weigh-ins are fake.

4. Kai Hibbard starred on the show in the third season and even made it to the final four. She lost 118 pounds in just 12 weeks. She also said she almost died, claiming that the show's practices led her to develop a life-threatening eating disorder.

The show continues to get monster ratings on NBC, so it's likely not going anywhere. But scandals are likely to keep rearing their heads as long as the show is on the air, as well.
