Kelly Brook has said she was suggested a weight-loss injection before going on the TV show ‘I’m A Celebrity…Get Me Out Of Here!’
The 45-year-old model, set to appear on the Australian reality show on Sunday, revealed her doctor suggested she try Mounjaro, but she declined, saying she’s happy with her figure.
Kelly recently shared on the ‘How To Fail With Elizabeth Day’ podcast that a doctor offered her the drug Mounjaro just last week, which she found surprising.
She explained that she’d asked why she needed something, and he simply replied that everyone else was using it. She told him she wasn’t interested, and when she asked about potential side effects, he claimed there weren’t any.
We had a long discussion, but I stuck to my guns. He’s aware I won’t be swayed because people keep trying to offer me things. I’m confident in my own preferences.
Kelly said she’s open to cosmetic procedures and treatments, but she won’t use weight-loss injections.


I really enjoy taking care of my skin with facials and massage. I get a little Botox to help with frown lines, but I do have limits. I’m very protective of my body and don’t like to make drastic changes to it.
‘I love my body, I absolutely love my body. I did a marathon this year, and I’m 45 years old.
I’m grateful for everything my body has allowed me to experience, and I embrace my figure. My husband appreciates it too. It’s a shame that so many women feel pressured to alter themselves.
Mounjaro is a prescription medication used to help adults manage type 2 diabetes, as well as weight loss for those with obesity or who are overweight and have related health problems.
As someone who really pays attention to health information, I’ve learned that the NHS defines obesity based on BMI. Generally, if your BMI falls between 30 and 39.9, you’re considered obese. But if it’s 40 or higher, that’s classified as morbidly obese – something that really highlights the importance of maintaining a healthy weight.
This follows Kelly’s recent confession about the extreme measures she’s taken to get more food while on the show, I’m A Celebrity…Get Me Out Of Here!
Even though she had said in the past that she wouldn’t do it, the former model will be appearing on the show alongside celebrities like Martin Kemp, Ruby Wax, and Alex Scott when the new season begins.
Before entering the jungle, Kelly revealed she’s been deliberately trying to gain weight by enjoying treats like chocolate, roast dinners, and wine. Her only other preparation was reducing her intake of caffeine and sugar.



Oh my gosh, she actually said it! She’s going to do the Myleene Klass shower scene! I can’t even breathe! She’s seriously packed a bikini, just in case, and I’m already picturing it. It’s going to be iconic, I just know it! I’m so ready for this!
Kelly explained she’d planned to hit the gym and go on some long hikes, but she hasn’t actually done any of those things yet.
I’ve been indulging a bit lately, enjoying treats like chocolate, roast dinners, and wine, to prepare for something special.
I felt a bit uncertain too, but I realized my worry was mostly about my dog and how it would cope while I was gone.
Okay, so I’m walking into this totally unprepared, let’s be real. But honestly? I survived Veganuary last year – a whole month fueled by beans! It was rough, but I know I can handle something… even if I have no idea what ‘this’ is. Seriously, beans are my superpower now.
Kelly explained she felt ready to take on the show after successfully completing both the London Marathon and Celebrity Race Across The World alongside her husband, Jeremy Parisi.
She admitted this would be the longest they’d ever spent apart from each other, but she’s choosing to think of it as a temporary break in their marriage.
Kelly became well-known for her curvy figure, initially gaining popularity as a lingerie model and appearing on Page Three of The Daily Star newspaper.
She also mentioned she’s prepared for the jungle with her swimwear, and jokingly suggested she might have a similar iconic shower moment to Myleene Klass.
She described the moment as truly iconic, admitting it was a little scary but that she was well-prepared with plenty of swimwear, including bikinis. She also expressed excitement about the potentially life-changing impact of participating in the program.
Many people describe feeling like a completely new person after going through this. They say it fundamentally shifts how they see the world, and that’s something I’m really hoping to experience myself.
‘I want to come out from something so mad, fun, and brilliant and have a spiritual awakening.’
In 2018, Kelly stated she’d prefer almost anything – even working at her neighborhood pub – to being on the reality show set in the jungle.
She said on her Heart radio show that she has no desire to try the unusual foods featured on the show, like eyeballs or sheep testicles.
‘Even if I had a huge tax bill and I had to pay it really urgently, I still wouldn’t do it.’
It seems she was convinced to participate after being offered a significant amount of money. She’ll be joining a group of well-known actors, musicians, and comedians when the show returns later this month.


The new season of the show starts this Sunday, and the first group of contestants heading into the Australian jungle includes Shona McGarty, Eddie Kadi, Aitch, Alex Scott, Jack Osbourne, Lisa Riley, Kelly, Angry Ginge, Ruby Wax, and Martin Kemp.
Vogue Williams, a well-known TV personality from Ireland, and Tom Read Wilson, famous for his role as the receptionist on Celebs Go Dating, are joining this year’s I’m A Celebrity…Get Me Out of Here! as latecomers.
Every year, two new contestants arrive a week after the initial group of ten celebrities. They usually have to finish a separate challenge before fully integrating into the camp.
I’m A Celebrity starts Sunday at 9pm on ITV1, ITVX, STV and STV Player.
