‘Great British Baking Show’ Judge Prue Leith ‘Didn’t Shed an Ounce’ on GLP-1

Great British Baking Show judge Prue Leith is opening up about her experience with the weight loss drug Mounjaro.

While speaking to U.K. paper The Times, Leith, 85, said she did try the type 2 diabetes drug after her husband, John Playfair, recently lost around 28 lbs. by taking the jabs.

However, she admitted she “didn’t shed an ounce.”

“I did try it,” Leith told the outlet. “I took it for two months, lost my appetite completely and didn’t shed an ounce. Nothing. Every day, I got on the scales and I still weighed exactly the same as before.” 

“I hated the bloody thing and I was tired all the time, presumably because I wasn’t eating. John said I looked thinner, which I think means old and scraggy round the face. And it’s expensive. As soon as I could, I stopped. It was terrible for me,” she continued.

Leith admitted she likes a glass or two of wine, but the jabs had meant that Playfair didn’t always want to join her for an evening tipple.

“He hardly drinks now and I’m a great boozer,” Leith told the paper. “I have two or three glasses of wine every night and he’ll only have half a glass, which he probably won’t finish. It’s a pity.”

Per the Cleveland Clinic, Mounjaro “treats type 2 diabetes by lowering blood sugar. It also helps with weight loss by reducing appetite and slowing digestion.” 

“You take it as an injection every seven days. Common side effects are nausea and diarrhea,” the site adds.

Elsewhere in the interview, Leith, who will turn 86 on Feb. 18, credited her genes for likely being the reason she remains so lively at her age.

She told The Times, “…I have no answer to that,” adding, “It must be genes, but I think it’s also because I eat well, I sleep well and I love well. In fact, I’m happy.”

Type 2 diabetes drug Ozempic and its fellow semaglutide drugs, such as Wegovy, as well as similar GLP-1 drugs containing tirzepatide, such as Mounjaro and Zepbound, have been getting increasingly popular in recent years.

While previously speaking to PEOPLE in 2023, Ania Jastreboff, M.D., PhD. — an obesity medicine physician scientist at Yale University, who is trained as both an adult endocrinologist and a pediatric endocrinologist — said that the drugs “work in the brain.”

Leith is the latest celebrity sharing her thoughts on weight-loss shots, with stars including Whoopi Goldberg, Rosie O’Donnell and Serena Williams being among those to speak out.

The latter spoke to PEOPLE in August about using a GLP-1 medication to help with weight loss. She said at the time that she’d lost over 31 lbs.

“I feel great,” the tennis champion, 44, told PEOPLE. “I feel really good and healthy. I feel light physically and light mentally.”
