Real Housewives of NYC, Bethenny Frankel

Real Housewives of NYC star Bethenny Frankel is on a mission to help everyone unleash their inner skinny girl with her new book Naturally Thin. But don't expect your typical Hollywood cayenne pepper-maple syrup-lemon juice quick-fix cleanse from this natural-foods chef.

Now a New York Times Bestseller for two weeks running, Frankel's book explains the techniques necessary to become naturally thin without all the fad diets, exercise and obsessing. "The title is a pun," Frankel told TVGuide.com. "Paris Hilton is not naturally thin," she claims. "She eats half a cheeseburger and French fries and walks away because it's not that important."

According to the reality star, Hollywood has clearly played an active role in our fixation with being thin. "You have these pages in magazines that talk about what a model or actress ate that says 'grilled salmon and steamed vegetables,'" says Frankel. "But that was one day of their life, and people think they have to live up to that."

One of the main rules Frankel promotes is to look at your food as a bank account where you make good and investments and bad ones; it all comes down to balance. "If you want a Krispy Kreme donut, have it. It's not like it's a great investment, but it's what you do next. Have a salad rather than beating yourself up. It becomes a new dialogue," says Frankel. "It's so stupid it's smart. It's not like I'm inventing fire; it's just new ways to think about things."

Frankel, who was once 15 to 20 pounds heavier than she is now, admits to having her own food issues. "I used to be afraid of avocado and oil and everything like that," said Frankel. "I was only that much heavier because I was obsessed. And it's ironic because I eat more now than I have ever eaten."

But super-skinny isn't what Frankel is touting. "A lot of Hollywood has an obsession with [being thin] and people that seem like they're healthy and normal all fall into it," says Frankel. "But at the same time, I think people are smart enough to know someone would rather sleep with a Rhianna or Beyoncé rather some skin-and-bones model. Only dogs like bones."
