Matt Lucas decided to lose after watching himself on television.
The 48-year-old TV star - who hosts Channel 4 baking competition 'The Great British Bake Off' alongside Noel Fielding - received a message from Lord Alan Sugar congratulating him on his transformation and replied by noting that he was inspired to lose the weight after realising that he could "barely fit" on the screen.
He tweeted: "Thanks. Basically, I was already pretty big and then I went into a large white tent and ate most of the cake inside. Then I saw myself on telly and thought 'I can barely fit on the screen and realised it was time to do something about it. That said, I have just had a Pot Noodle!"
The 'Little Britain' star once weighed a reported 14 stone and previously explained that he knew he had to do "something" about his diet during the COVID-19 lockdowns.
During an appearance on ITV's 'Lorraine', he was asked: "How on Earth though, have you been in lockdown and working on Bake Off and you've lost tonnes of weight?"
Matt replied: "I've lost some weight, I needed to take the edge off, because I put on a lot of weight in lockdown,
"I just had to do something about it.
"I've still got a bit of a tum, I've got a little bit of a tum, I'm not a skinny Minnie.
"I might have to make a game of it when I go out and exercise to stay out of people's way. I don't have a garden so I have to find a way to do that."
