Washington, Mar 25 : The Real Housewives of New York star Bethenny Frankel says she can help talk show queen Oprah Winfrey lose those pesky pounds and keep them off.

And the trick is: her new book, Naturally Thin: Unleash Your SkinnyGirl and Free Yourself from a Lifetime of Dieting.

"I never thought about writing a book, but I figured out how to be thin and not obsessed and I was like `wow' so I had to write about it. I know how much my friends and I struggled. All I talked about was what I ate and I worked out all the time, now I don't even work out that much - maybe two days a week if I can," Fox news quoted Frankel, as saying.

"Women in America are going to be thinner because of this book, Oprah is going to be thinner, nobody needs to freak out anymore," she added.

The 38-year-old reality starlet has been very open about her weight struggles and eating disorders since childhood and even admitted it wasn't so long ago that she was easily 15-20 pounds heavier.

"Being skinny didn't come easy for me, I was on every single diet and grew up in a life of diet obsession and food noise. But now I've freed myself and I can worry about other things, (ANI)
