Mark Labbett, known as The Beast from the popular quiz show The Chase has shown off his incredible weight loss to fans.

He shared a snap on Instagram of himself dressed in a suit.

“What’s more likely? Bit part in next Kingsman or Oddjob in the Goldfinger remake?,” Labbett wrote.

Fans were shocked by the 55-year-old's transformation.

“Looking fabulous,” one commented.

Labbett revealed that his type 2 diabetes diagnosis inspired him to lose weight.

“My colleague Paul Sinha also got the diagnosis and he rapidly lost two stone (12.7kg) and he went from being diabetic to pre or non-diabetic,” he told Loose Women.

“I’m still eating very well – I’m just cutting out sugar because of the type 2 diabetes.”

Labbett has documented his weight loss on Instagram in previous posts, much to the delight of fans.
