Jeremy Clarkson's Mounjaro weight loss: 3 stone gone, side effects revealed
Jeremy Clarkson loses 3 stone on Mounjaro

Television presenter Jeremy Clarkson has openly discussed his significant weight loss journey, crediting the drug Mounjaro for helping him shed an impressive three stone.

The Mounjaro effect: Weight loss and unexpected changes

Clarkson, the 65-year-old host of Who Wants To Be A Millionaire?, revealed his experience in an interview with The Sun's Sun Club. While the weight loss jab successfully helped him lose a substantial amount of weight, he also spoke candidly about its less desirable side effects. He humorously noted that, unlike some other users, he did not suffer from constipation.

However, Clarkson pointed to a diminished libido as a potential consequence of the treatment, joking that the medication has made him feel "duller" and less quick-witted. "I'm 65 - it's hard to know what's causing that," he remarked about his reduced sex drive. He also shared that he sometimes finds himself reflecting on missed opportunities for witty remarks during filming, though he concedes it's unclear if the drug is to blame.

Partner's approval and a healthier lifestyle

Despite the side effects, Clarkson's partner, Lisa Hogan, is reportedly pleased with the results. He shared that she likes the "thinner me," though he modestly compared his transformation to the slow movement of tectonic plates, stating he is now only slightly closer to looking like model David Gandy than he was a year ago.

The more practical benefits have been a major positive. Clarkson emphasised his improved health, noting he now has the energy to take the dogs out for much longer walks, which contributes to a happier home life. This shift towards increased physical activity marks a significant change in his daily routine.

An unusual consequence: Losing weight in his feet

In one of the more surprising revelations from his weight loss journey, Clarkson disclosed an unusual problem: he has had to buy new shoes. The dramatic change in his body has even affected his feet, causing his old footwear to become loose.

"The shoes I was wearing last year are falling off me as I'm walking around," he explained. "I think I might be the first person in the world to lose weight on my feet." This quirky detail highlights the comprehensive physical transformation he has undergone since starting the Mounjaro treatment.

Clarkson's frank discussion, dated from his interview on 3rd January 2026, provides a real-world look at the successes and personal challenges of using pharmaceutical aids for weight management, moving beyond simple before-and-after stories to address the nuanced reality of such treatments.
