UNBELIEVABLE: ITV’s Claer Barrett just shocked viewers on Lorraine with a transformation so dramatic even Lorraine Kelly was left speechless
Claer Barrett is used to talking numbers. But this week, the ITV regular found herself sharing a very different kind of figure — one that marked a turning point in her life rather than her finances.
Appearing on Lorraine, the respected personal finance expert revealed she has lost four stone and dropped four dress sizes, moving from a size 20 to a size 14 after beginning a medically supported weight-loss programme last year. The change, she admitted, has been as emotional as it has been physical.
Barrett explained that her journey began after being clinically diagnosed as obese, with a BMI of 37 — a moment she describes as confronting, but necessary. Rather than chasing a quick fix, she first took part in a 12-week NHS weight-loss course before later using Mounjaro, part of a new generation of appetite-regulating medications.
Far from presenting the process as effortless, Barrett was keen to stress that the injections were only one part of a much wider lifestyle shift. Regular exercise, dietary changes, and learning to listen to her body all played a role — something host Lorraine Kelly was quick to acknowledge.

“You’ve done the work,” Lorraine told her, praising not just the weight loss, but the commitment required to sustain it.
Still, Barrett approached the conversation with her trademark humour. Joking that she was now “healthier but poorer,” she laughed about the unexpected downside of success — a wardrobe that no longer fits. “In my head, I’m still a size 20,” she admitted, “but reality says otherwise.”
The segment culminated in a light-hearted makeover, with stylist Mark Hayes helping her explore clothes that reflect her new shape. Yet the moment felt less about fashion and more about confidence — a woman learning to see herself differently after years of feeling defined by a number on the scale.
The discussion also touched on the wider debate surrounding so-called “fat jabs,” which have divided public opinion. While some critics question their popularity, medical professionals continue to highlight their potential benefits for people facing serious obesity-related health risks.
For Barrett, the focus remains firmly on sustainability. Maintaining the weight loss, she said, will be the real challenge — and one she’s approaching with the same honesty she brings to her money advice.
In sharing her story, Claer Barrett offered viewers something rare on daytime television: not a miracle transformation, but a nuanced, human account of change — complete with effort, humour, and the quiet courage it takes to start again.
