However, speculation she used the appetite suppressant drug commonly used to treat type 2 diabetes kicked off again after reports WW CEO Sima Sistani is embracing the use of semaglutide drugs like Ozempic.
During Wednesday's episode of The Kyle and Jackie O Show, Jackie told newsreader Brooklyn Ross, "That makes it look like I was definitely on Ozempic!"
"I was like a guinea pig in that experiment," she joked.
Brooklyn asked Jackie if she was "annoyed" that she lost weight "the hard way" and not with Ozempic for a faster result.
"I mean, they make a good point and I'm really impressed that they're with the times," Jackie said. "You see so many people doing it and being successful and it not really being that hard for them."
Jackie has also denied using the drug during an interview with the Something To Talk About podcast for Stellar Magazine.
"When the Ozempic rumours first came out, I was like, 'Oh, are you joking?'" she said. "I know how hard I've worked and I haven't taken that."
She continued, "I was frustrated when those were coming out and I found the more I was defending myself, the more I felt, okay, this is a losing battle."
Jackie said she knew she'd never be able to convince people she was telling the truth, adding, "The people who believe I have or was taking Ozempic, you're never going to change their mind. Because I think they want to believe it."
"I know I didn’t take any shortcuts. It's just not what I did. I can't really deny it any more than I have. I'll take a lie detector test. You got one?" she joked.
