Jez the jab!

TV star Jeremy Clarkson has joked that his trousers keep falling down - after revealing that he’s been using the weight-loss jabs Mounjaro to shed the flab.

The 65-year-old has lost two stone, helped by the products, since he underwent surgery to clear blocked arteries.

And he’s not the only star to swear by the injections. The likes of TV’s Gemma Collins and Sharon Osbourne have used them to slim down, along with an estimated 1.5 million other Brits.

But could you benefit? Here JAMES MOORE has put together a chunky Q&A guide to the weight-loss wonders..

What are the jabs? ‘They're drugs, delivered by injection, that help you lose weight by suppressing appetite. ‘They are available to some through the NHS to treat obesity and people who are overweight with other conditions. ‘They can also be bought privately.

How do they work? By mimicking hormones in the body which regulate hunger and cause you to feel full. They slow down digestion and the time it takes for your tummy to empty too and can also regulate blood sugar and energy levels, helping to reduce cravings.

What are the different types? The best known are Wegovy and Mounjaro. Wegovy contains the drug semaglutide and is known as a GLP-1 receptor agonist. This means it acts like the naturally occurring GLP-1 hormone in the body, sending signals to your brain that you've eaten.
