Mark Labbett, better known as The Beast on the TV quiz show The Chase, has revealed his secret behind his staggering 60kg weight loss.

The quizmaster has credited his lifestyle change and body overhaul to his adorable golden retriever, who he branded as his “personal trainer”.

On a UK chat show, Mark said that his pooch Baloo helped him get into the habit of daily exercise.

“My wife promised me that when we first got him she would take care of everything – feeding him, walking him and so on,” he explained.

“That lasted about two weeks before she decided ‘Actually Mark, look at your belly – you need the exercise!’”

Mark and Baloo formed a special relationship and now refers to the dog as his “personal trainer”, who incidentally costs a lot less than a human personal trainer.

He continued, “I was walking him around the fields, taking me places … I think he’s helped a lot, simply because I’m doing more activity.”

Mark has been documenting his weight loss on Instagram, with many followers cheering on his success in the comments.

Mark has previously opened up about his weight loss on the chat show Loose Women, and how he has dropped several clothing sizes along his journey.

He said, “I am gradually dropping Xs off my size. I’ve gone from 5XL to 4XL and it looks like the next time I go shopping I’ll be able to squeeze into XL underpants.”

Mark also opened up about when he was at his biggest, admitting, “I’ve lost 10 stone (60kg), I was 29 stone (184kg) when I was a full time teacher in 2003 and I was in danger of high blood pressure.”

“I’ve been around 26 stone (165kg) up until lockdown, and then a few things happened quite nicely and came together and I started losing weight.”
