Simon Cowell has revealed he’s gone fully vegan – and he will never look back after seeing drastic improvements to his health after ditching meat and dairy.

The Britain’s Got Talent judge and X Factor mastermind had been told by a doctor that he had ‘every allergy going’ – and was advised to cut out meat, dairy and fish.

In an interview with the Sun, he revealed: “Within 24 hours I changed my diet and I’ve not looked back since. You feel better, you look better.

“I cut out a lot of the stuff I shouldn’t have been eating and that was primarily meat, dairy, wheat, sugar — those were the four main things.

“I loved those comfort foods, that’s all I’ve eaten all my life. I love jam tarts, hamburgers, spaghetti Bolognese. I can eat fish but this year I will go the whole way.”

Cowell, who is approaching his 60th birthday this year, was evaluating his health and life choices after suffering a fall recently.

He reportedly made the switch after auditions for his flagship UK talent show this year.

He added: “I have cut down though, because with this job, you’ve got to be fit, you’ve got to be on it and you’ve got to be ruthless, you need a clear mind.”

The Britain’s Got Talent judge also reportedly lost 20lbs soon after switching to veganism this year.

Cowell’s switch to veganism is a breath of fresh air after recent news about high-profile vegan figures.

This year has seen famous YouTuber Rawvana and former vegan athlete Tim Shieff come under fire for the controversial ways in which they abandoned the diet.

Vegans celebrated Simon Cowell’s news on social media. Animal rights organisation PETA said it’s ‘pushing the golden button’ on his revelation.

Vegan chefs BOSH! offered some handy cooking advice.

And fans celebrated the transition of a megastar to a plant-based diet.
