Fans have been quick to respond to the talented quiz player, with some sharing they thought the photo was a throwback to his younger years.

“Is it bad I thought this was a throwback pic of you as a teen!? You’re looking way younger, Beastie!!!” commented one.

Another wrote: “B***dy hell, actually didn’t think that was you and thought it was possibly your son or a relative lol.”

Others commented on Labbett’s weight loss, with one fan asking: “Is that you Beastie Boy? What’s Brad going to call you now? Seriously well done with the weight loss looking good. Pointless present though.”

Another penned: “Wow, I didn’t recognise you. You’re doing amazing at the weight loss,” and another said: “Jesus, almost didn’t recognise you, really smashed that weightloss.”

According to The Sun, Labbett achieved his dramatic weight loss by making small changes over time.

During an appearance on British Talk Show Loose Women, he revealed he’d “gradually dropped x’s off my size from 5XL to 4XL” and said when he next went shopping he expected he’d be able to squeeze into XL pants.”

Labbett also said his diabetes medication helped him eat less and he drinks “a lot more fluids.”
