Denise Welch has admitted she wouldn't have been able to take part in new dance show 'Stepping Out' had she not lost two stone on the Lighter Life diet beforehand.
“There's no way I could be doing it if I hadn’t lost the weight - partly from a vanity point of view but definitely from a health point of view. Losing weight has given me a new lease of life," she said.
"My GP says there is a 90% improvement in my knee which is down to the weight loss."
She added: "I really, really do believe that LighterLife is what it says on the tin. It leads to a lighter life and not just physically but mentally. It's the best life-changing plan that I've ever done in my life."

'Stepping Out', hosted by Davina McCall, starts this Saturday at 6.30pm on ITV.
