The Chase's Mark 'The Beast' Labbett shows off impressive 60kg weight loss in new picture

We've known him as 'The Beast' for as long as he's been famous, but Mark Labbett isn't looking very beast-like anymore ...

The 55-year-old chaser - who stands very tall at 6’ 7” - shocked fans of The Chase this week after he posted a new photo of himself looking considerably slimmer.

The TV star, who has dropped 60kg, showed off his dramatic weight loss as he modelled a black suit and tie. 

Alongside the photo, he wrote: "What's more likely? Bit part in next Kingsman or Oddjob in the Goldfinger remake?"

At his heaviest, in 2016, Mark weighed 184kg.

He now weighs less than 120kg and hopes to lose even more following his diabetes diagnosis at the end of 2017.

The father-of-one previously opened up about how his diagnosis of type 2 diabetes was the driving force behind his dramatic weight loss.

"It was the diabetes. My colleague Paul Sinha also got the diagnosis and he rapidly lost two stone and he went from being diabetic to pre or non-diabetic," Mark said.

Mark also revealed that there is another heartwarming reason behind it: "I want to be around long enough to see the little man get the university degree."
