The 56-year-old, who stars on the UK, US and Australian versions of the game show, has gone through quite a transformation recently.
Speaking on The Pet Show in the UK, Mark revealed that he credits his impressive weight loss to his Golden Retriever named Baloo.
The TV star explained that having a pet, who he calls his “personal trainer”, helped him get into a regular exercise routine.
“My wife promised me that when we first got him she would take care of everything – feeding him, walking him and so on,” he began.
“That lasted about two weeks before she decided, ‘Actually Mark, look at your belly – you need the exercise!’
“I was walking him around the fields, taking me places,” he continued. “I think he’s helped a lot, simply because I’m doing more activity.”
Mark also appeared on the British talk show Loose Women to discuss the secret behind his transformation, joking that it has to do with spending a lot of time “running around after a hyperactive three-year-old in lockdown”.
He also added that his weight loss journey “kick-started” when he got Covid last year and lost his sense of taste, so he didn’t want to eat for a fortnight.
‘The Beast’ went on to detail his current eating habits which have led him to “gradually drop X’s” off his clothing size.
“I’m on a high protein diet,” he said. “So eating an awful lot of lean meat, and as much as I love chips and other carbs, I’m having quite a bit less than I used to.
“And it’s sort of became a virtuous cycle. I’m not feeling that hungry, so you eat less, so you lose weight, so you’re not as hungry.”
Mark has been documenting his transformation on social media over the past year and has been met with resounding support from his followers.
“Wow, unbelievable achievement,” one fan commented, followed by another who said he looks “amazing” and should be proud.
“Well done and congrats! I bet you feel much better in yourself and have gained so much more energy, never go backwards!” someone else added.
“You look strong and confident, keep shining!” a fourth remarked, while a different user called him “a lean mean quizzing machine!”.
