"What Not to Wear" star Stacy London spends her days making over other people's lives but now the star is opening up about her own makeover past. In her early 20s, London battled anorexia and compulsive overeating.

With extreme dieting that led to anorexia, London whittled her 5-foot-7 frame down to 90 pounds.

"I felt like I'd never had a serious boyfriend and I really wanted to be attractive," she told People magazine.

London's weight struggles shifted after a brief hospitalization. The TLC star turned to binge eating, which brought her to 180 pounds a year later.

London, 43, chronicles her weight struggles in her new book, "The Truth About Style," out Oct. 2. She hopes her story will help others who battle eating disorders.

"When you can talk about something and shine light on it, you're obliterating shame," London said. "And that to me was always the really hard part, to feel so filled with shame and having no recourse to thinking it could get better."

London is no longer trying to make over her body. She is just happy being herself.

"My value doesn't simply come from [being thin]," she said. "It comes from me and solely from me. It took me a long time to recognize that."
