Dunbar, 61, who plays Superintendent Ted Hastings to This Morning recently: “We were a month in, and we had to stop, we had to go away.
"I'm kind of worried to tell you the truth, about what's going to happen...because a lot of us are eating quite a lot.
"Vicky McClure is up in Nottingham and she's on Rich Tea, you know what I mean?
"Martin will keep himself trim no matter what happens, but me and Vicky have got to watch it."
