The UK McDonald's boss has claimed Big Macs are healthier than sandwiches available on the high street.

CEO Paul Pomroy made the claim and revealed he eats at the chain twice a day.

The fast-food chief said a Big Mac weighs in at 508 calories, but some high street stores could have more calories in their lunchtime alternatives.

However his claims did not take into account breakdown of fat, sugar and salt content in each product.

He told the Evening Standard: "I challenge you to find a sandwich in a High Street chain that's less than that.

"Do I have a Big Mac and fries every day? Of course not. I treat myself once or twice a week.

"But I eat a McDonald's twice a day and I’ve just flown through my health check."

He also revealed he has just 'one per cent chance' of having a heart attack despite enjoying food from McDonald's daily.

Greggs' Mexican Chicken Baguette comes in just ahead of the McDonald's offering with 518 calories.

A Southern Fried Chicken Wrap from Waitrose boasts 533 calories.

Tesco tops that with its chicken sandwich containing a massive 634 calories.
