The star was inspired to change his lifestyle after he was hospitalised in October 2017 after fainting while going down the stairs as a result of low blood pressure.

Speaking last month about his new diet, Simon told Extra: ‘I went to see this guy who’s very well-known. And he said to me, after doing some blood work, “You can’t have red meat, dairy, sugar, bread or gluten.”‘

But the X Factor boss added that his first thought following the advice was ‘What about alcohol?’.

Laughing, Simon said: ‘And he said, “Maybe not quite as much as you had before.” And I did it and I stuck to it and it’s easy.’

The talent show judge confessed he was following his five-year-old son Eric’s diet, explaining: ‘Apart from ice cream, he actually likes water, and eats all his raw vegetable. I’m on the Eric Cowell diet.’

A source recently told the Daily Mirror the music mogul has ‘lost half a stone’ thanks to his new healthy lifestyle and has had ‘a real spring in his step’.
