Simon, who is a regular smoker and drinker, recalled asking his doctor what he needed to give up in order to improve his health.

"It's pretty much all the things I loved that I can't now eat. So no dairy, no sugar, no bread, no gluten, no red meat," he said.
"I've gotta be honest with you, it was easier than I thought. And part of the reason I did it was because Eric is five this year so I realised that if I didn't sort myself out physically I wouldn't be able to catch up with him."
