Maureen McCormick on 'Celebrity Fit Club'

LOS ANGELES, Nov. 27 (UPI) -- The fifth season of "Celebrity Fit Club" on VH1 will see "The Brady Bunch" star Maureen McCormick trying to lose 25 to 30 pounds.

"My daughter said, 'Mom I think you should do it,'" said McCormick when asked why she agreed to appear on the reality show. "For the past few years, I had been totally out of exercising, just eating and going crazy. I thought, 'What a great opportunity to do something positive.'"

McCormick has admitted to suffering from bulimia in her early 20s and late teens, and said she is hoping to lose the 25 to 30 pounds she has gained since her mother died, "Entertainment Tonight" reported Monday.

"I have had a lot of hard things going on in the past few years of my life," she told ET. "My mother was my best friend. It was really hard going through her illness with her. I have a brother who is mentally retarded, and about a month before my mother died, my father came to me and said, 'I need to put Denny into a home.' That was really, really difficult."
