This Is Kate Hudson's Weakness When it Comes to Food

With the body she's got, it's hard to believe that Kate Hudson ever strays from her diet. But, alas, she does, although what she chooses to indulge in isn't exactly everyone's cup of tea—or slice of pizza, in this case.

In the new issue of People, Hudson reveals that her weakness is Hawaiian pizza. "I'm always the person that orders the pizza that everybody goes, 'Why did you order that?'"

The reason Hudson is able to allow herself these indulgences has to do with body acceptance. The actress-turned-author, whose book Pretty Happy: Healthy Ways to Love Your Body is out later this month, admits that it's been a struggle for her to come to terms with her own body. "I have fluctuated [in weight] my whole life," she tells People.

"I fluctuate at least five pounds every month. I really want to reach people that are asking, 'How do I get there?' A lot of people are quite discouraged by the process of getting healthy because one, they think they can't afford it and two, it's daunting." Hudson says she penned the book to help people accept and connect with themselves.

"It's about health and mindfulness," she says. "Because you can have the greatest body and you can be really unhappy if that's all your working toward." For more of her interview head over to people.com, and pick up Hudson's book when it hits shelves on Feb. 16.
