Richard Osman claims his 'tricky' food addiction battle is tougher to beat than alcoholism
The Pointless star's debut novel, The Thursday Murder Club, saw him named author of the year at the 2021 British Book Awards.
Hollywood producer Steven Spielberg even holds the movie rights to the book.
His follow up book, The Man Who Died Twice, finished runner up in this year's official Christmas book chart, with the book itself becoming one of the fastest selling novels since records began.
In September, Osman told the BBC he is not going to get complacent about his achievements.
"I've been through my creative life with great TV shows that fail and not-so-great that succeed so I'm rarely surprised by anything," he said.
"But I'm humbled and amazed.
"I'm thinking 'what a lovely thing to have happened and I get such lovely comments in the street, but I'm with Kipling on success and failure: you have to treat them in just the same way'."
Richard Osman's Desert Island Discs episode is on BBC Radio 4 on Boxing Day at 11am
