Gregg Wallace has impressed TV fans with his new slender look.
MasterChef : The Professionals returned to BBC screens on Monday night and viewers were all left commenting the same thing - how much weight Gregg has lost.
The former greengrocer, 57, was reunited with Marcus Wareing and Monica Galetti last night, to judge the first of the four competitors of the show's 14th season.
Those tuned into the BBC show couldn't help but spot Gregg's impressive new physique - with many taking to social media to pass comment on the culinary star's body.
Gregg - who once referred to himself as "just the fat, bald bloke on MasterChef who likes pudding" - has lost over four stone in recent years.
The TV presenter recently revealed how he achieved the impressive weight loss and his motivation for doing so.
Gregg confessed he was "scared" when doctors told him he would die if he didn't change things due to his cholesterol being so high.
"So, it started there, and then there were a couple of motivating factors along the way. Meeting my beautiful, lovely wife [Anne] who's a lot younger than me," he explained to HELLO! in August.
"I thought, well she's obviously alright having an old boyfriend, or now an old husband - but there's no reason why she should have to have an old fat husband is there!"
The BBC presenter went on to admit that he doesn't deprive himself of treats and can still enjoy a kebab or a takeaway curry despite his new healthy lifestyle.
"We've got to live right - there's no way I'm going to the rugby and not having a pint of beer," he joked.
"It would be like washing my feet with my socks on. It just isn't going to happen."
Gregg went on to reveal that over the last three years, he has been exercising five days a week in a bid to change his lifestyle.
He added that when filming MasterChef, he visits a personal trainer located near the studio.
On Monday night's episode of the BBC series, Gregg, Monica and Marcus revealed how to make perfect bangers and mash.
Michelin-starred chef Marcus was in charge of picking the new series first skill test and set out what he was expecting from this year's hopeful contestants.
The culinary star showed viewers just how he makes his version of the classic English dish, adding his own touch with a stout gravy.
Presenter Gregg was on hand to quiz the chef on why he picked bangers and mash to kick start the new series.
"It's not only a home-cooked dish, it's a pub dish, it's a restaurant dish," he explained.
"There are lovely, little key skills in here Monica and I will be looking for."
MasterChef: The Professionals next airs Thursday, 9 November at 9pm on BBC One.
