The 53-year-old comedienne stated that she had been prompted into shedding over 35kg for health reasons.
“I think when you’re over 50 you have to pay attention to your health a bit. I want to be there for my kid, and I’ve got quite a lot of exciting adventures that I want to do.
“I had just ballooned up more than I had wanted to, but you can always address it. You just have to eat less and walk more – that’s what I’m doing.”
Dawn, who split from husband Lenny Henry in April 2010, also spoke about her dating life and admitted she’s enjoying being a single woman once again.
She said, “Who knows what will happen? I’ve been married for such a long time, the last thing I want is to be in a big relationship.”
