Dame Prue Leith, the 86-year-old television cook, has revealed that the weight loss injection Mounjaro did not work for her, calling it a “waste of money”. Despite using the medication for a month, she said she “did not lose a single pound”.
The culinary icon admitted the jab “didn’t do anything” for her, contrasting sharply with her husband John Playfair’s success. He reportedly lost three stone and became healthier after using Mounjaro, inspiring Dame Prue to try it.
However, she confessed that her lack of adherence to instructions was likely the cause. She told the Press Association: “I tried, but it didn’t do anything. I didn’t read the instructions.” She inadvertently consumed only around 200 calories daily, sending her body into “starvation mode”.
She explained: “I reckon I was eating 200 calories a day, which I didn’t realise. And what your body then does is it simply says, ‘this is starvation. I mustn’t let anything go’. I did not lose a single pound.”
Reflecting on the experience, she concluded: “I don’t think I need to (use it). It’s bloody expensive, and I think if it’s not going to work, it’s a waste of money.”
Dame Prue also discussed her dietary habits in her latest book, revealing that during her tenure on The Great British Bake Off, she never gained weight despite a diet of cake and red wine. She stepped down from the show last month, with Nigella Lawson confirmed as her replacement.
