Rewind a decade or so, and Jeremy Clarkson had a particular disdain for exercise, healthy eating and denying himself life’s pleasures. He never worked out, smoked 40 cigarettes a day and, in his own words, drank four pints of wine daily. Now, at 65, his entire outlook on health and longevity has shifted.

At the heart of Clarkson’s desire to change are his young grandchildren.

‘I’m not going to dwell on the joys of being a grandparent because what can be said about it has already been said. But I have decided that it is so wonderful that I want it to go on for as long as is humanly possible. Which means I must do everything in my power not to die,’ he wrote in his column forThe Times.

And the British TV personality has certainly had a couple of wake-up calls.

After being admitted to hospital with pneumonia in 2017, Clarkson then suffered what he described as ‘really bad coronary artery problems’ at the end of 2024. Documented in the latest series of Clarkson’s Farm, he experienced a ‘sudden deterioration’ in his health and needed a stent fitted to restore proper blood flow.

Why Clarkson Finally Started Taking His Health Seriously

Since then, he has taken up reformer Pilates, had a pickleball court installed at his Oxfordshire home and started going for walks when the weather is just right.

‘Eventually, I decided that organised, indoor exercise was not for me and decided instead to do walking. Not when it’s raining obviously. Or if it’s too cold, or hot. And not if I’m busy. But on a reasonably temperate Sunday morning, I’d get out there and pootle along,’ he wrote.

‘So far I’ve relied on luck to keep me alive. But I’m in sniper’s alley right now and I have to work at dodging the bullets. Two years ago, I saw old age as a wearisome tangle of tubes and knee-replacement surgery. Now though, thanks to my grandchildren, I’m actively looking forward to it.’

Clarkson’s comments highlight just how much his attitude to ageing has changed.

‘I’m buying time. It hurts and it’s expensive. But it’s better than wasting your money on a new watch.’

The Diet Changes Behind Clarkson’s 3-Stone Weight Loss

Diet has also become a key part of his health overhaul.

He now eats burgers wrapped in lettuce rather than buns and opts for alcohol-free versions of his Hawkstone beer. Underpinning much of that change has been a microdose of the GLP-1 medication Mounjaro, which Clarkson credits with helping him lose more than three stone in six months by suppressing his appetite – although he admits he doesn’t particularly enjoy the experience.

‘When you are on Muntjac [his name for Mounjaro] you can come down in the morning and idly help yourself to a small handful of sunflower seeds,’ Clarkson said. ‘And it’ll feel like you’ve just finished a massive Christmas lunch. You’re stuffed.

‘So you find yourself living a minibar existence. Tiny packets of milk, sachets with only three grains of sugar in them, vodka in thimbles. That’s not living, though. That’s existing.’

Having graduated from Cardiff University in 2020, and later obtaining his NCTJ qualification, Ryan started his career as a Trainee News Writer for sports titles Golf Monthly, Cycling Weekly and Rugby World before progressing to Staff Writer and subsequently Senior Writer with football magazine FourFourTwo.

During his two-and-a-half years there he wrote news stories for the website and features for the magazine, while he also interviewed names such as Les Ferdinand, Ally McCoist, Jamie Redknapp and Antonio Rudiger, among many others. His standout memory, though, came when getting the opportunity to speak to then-Plymouth Argyle manager Steven Schumacher as the club won League One in 2023.

Having grown up a keen footballer and playing for his boyhood side until the age of 16, Ryan got the opportunity to represent Northern Ireland national futsal team eight times, scoring three goals against England, Scotland and Gibraltar. Now past his peak, Ryan prefers to mix weightlifting with running – he achieved a marathon PB of 3:31:49 at Manchester in April 2025, but credits the heat for failing to get below the coveted 3:30 mark…
