Jeremy Clarkson reveals unexpected side effect of Mounjaro he experienced at airport

Jeremy Clarkson reveals he was caught out with an unexpected side effect of Mounjaro while in the airport.

An estimated one in eight adults, a staggering 12 percent of the US population, have turned to the 'fat loss' jabs in a bid to shift some stubborn pounds.

These GLP-1 drugs work by mimicking a natural hormone which regulates blood sugar levels and makes users feel fuller for longer.

It means users have a reduced need to eat, and as a result can enjoy some significant weight loss.

Although the purpose of the medication is to treat type 2 diabetes, with Ozempic not technically approved by the FDA for weight loss, it hasn't stopped people including the rich and famous from using them.

British TV presenter and Top Gear star, Clarkson, is apparently one of the latest celebs to have confessed to using the jabs - as he revealed he suffered quite an embarrassing blunder at airport security as a result.

The 65-year-old said in a post on X, formerly Twitter, he had a 'Mounjaro problem' he 'never saw coming.'

"At airports you’re made to remove your belt and then told to stand in the body scanner with your arms in the air," Clarkson penned.

This is apparently a problem as he said the situation means 'you can't hold your trousers up.'

The Clarkson's Farm documentary maker appeared to joke about having lost a significant amount of weight on the drug, so much so that his trousers no longer fit and, presumably, dropped to the floor when he was scanned at airport security.

His hilarious blunder comes as scientists recently put the top three blockbuster jabs, Mounjaro, semaglutide (in Wegovy and Ozempic) and Saxenda to the test, which ultimately crowned Mounjaro as the best of the bunch.

The results, published in the Cochrane Database of Systematic Reviews, determined tirzepatide (the active ingredient in Mounjaro) helped patients shift the most weight and crucially keep it off for longer when compared to rival GLP-1 medications.

Mounjaro patients lost an impressive 16 percent of their body weight in just 12 to 18 months on the drugs, according to the review, and were able to maintain their new physique the longest by up to 3.5 years.

Doctor Crystal Wyllie at ZAVA also says Mounjaro effects are likely to kick in as early as week two.

As for weight loss, she said it's likely around the week four mark that users will experience a physical change in their physique - or at least the number on the scale has gone down.

According to ZAVA, patients lose an average of four per cent of their starting body weight on Mounjaro within the first month.

So, if you're starting out on the drugs and are planning a trip any time soon, perhaps pack a spare pair of trousers so you don't get caught out like Clarkson...
