Former EastEnders actress, Natalie Cassidy, is regretting making her fitness DVD and is admitting it is one of her biggest mistakes.

Her bestselling Then and Now Workout DVD was released in 2007 after losing weight with the help of a personal trainer - however, the actress began to struggle to maintain her figure and ended up putting the weight back on, rising from a UK's size 8 to a size 14. (In U.S. sizes I think it's a size 6 to a size 12)

Natalie opened up on This Morning, she explained:

"I did let the wolf to the door. By doing the DVD I was setting myself up for a fall. And I'm not ashamed to say that you live and learn by your experiences and if I could go back I wouldn't do the DVD."

"Not only do you set yourself up for a fall, but I like to consider myself an actress and presenter, and I think that takes you down the celebrity route, so you live and learn. But I know I did it. I showed people I could do it. The big thing for me was that I didn't want people to feel let down."

She also admitted to resorting to drastic measures to keep her dream figure by adding:

"I would take laxatives before I went to bed which was very dangerous and very stupid. I started doing this about three or four months after doing the DVD."

Cassidy has previously confessed that she was "bordering on having an eating disorder" at the time of the press attention which surrounded her weight.
