The first couple of days on the detox diet aren't pleasant.

Turning 50 changed me and I'm far more accepting of myself. I'm not thin, but I am a size 10. I go in at the middle and very much out at the bottom and top. And now I think, 'Well, that's how I am.

I'd be happy to stay single now because I've always been in relationships. For the first time ever I can do what I want, when I want, with who I want, without answering to anyone.

Ruby Wax has basically ruined my career. You'll see when you watch the programme. I get more intimate with Ruby than I've ever been with another woman.

How you look has become ridiculously disproportionate to what you do. Critics are more harsh on female presenters.

I can't be bothered to go to the gym, though. I honestly just can't be bothered - it's the most boring thing on Earth. I have tried and every six months I go 'right, I'm going to the gym'. Then I do it for two weeks and get so bored by it.

I have had stalkers over the years. The police deal with it but it is very scary. One man kept turning up where we filmed 'Countdown in Leeds,' which was scary. It was sad as he'd been sectioned and thought I was talking to him through the TV.
