Kai Hibbard, a former contestant on The Biggest Loser, is breaking her silence and slamming the same show that helped her drop the weight.

“The whole f–king show is a fat-shaming disaster that I’m embarrassed to have participated in,” she said.

She explained the weight loss became detrimental to her health — but she was pushed to keep going because it was about shedding the most pounds, regardless of the consequences.

“My hair was falling out. My period stopped. I was only sleeping three hours a night,” she said — adding that some of the damage has proven to be permanent. “One of the other ‘losers’ and I starting taking showers together because we couldn’t lift our arms over our heads. We’d duck down so we could shampoo each other.”

Kai isn’t surprised people stick with the show. Explaining, “You’re brainwashed to believe that you’re super-lucky to be there. I was thinking, ‘Dear God, don’t let anybody down. You will appear ungrateful if you don’t lose more weight before the season finale.’”

When Jillian Michaels left the show, it was allegedly over concern about how they treat contestants. Now, after losing 121 lbs on the show, Kai feels a similar responsibility.

“If I’m going to walk around collecting accolades, I also have a responsibility [to tell the truth],” she told The New York Post. “There’s a moral and ethical question here when you take people who are morbidly obese and work them out to the point where they vomit, all because it makes for good TV.”
