She loves to share the tips and secrets she's discovered to looking and feeling good.
"I love sharing information like, 'OK, you need to go blond. Don't forget about your eyebrows. ... Oh my god, you've got to check out this smoothie. OK, so I just went to this place and I swear to you I lost three pounds,'" she said in a recent interview.
Sims has compiled some of her tips for looking and feeling great in her new book, "The Everyday Supermodel: My Beauty, Fashion, and Wellness Secrets Made Simple" (Dey Street Books). She enlisted the help of experts like stylist-designer Rachel Zoe and Pilates instructor Alycea Ungaro.
Associated Press: Do you really believe that by following your book, the everyday woman can look like a supermodel?
Sims: I knew I was gonna get a little flak on 'The Everyday Supermodel' because here I am calling myself a supermodel. I cringe sometimes at the word, but ... I've done this for 20 years. I've made myself believe like, 'OK, I can do this. I can challenge myself. I can respect myself and I can be the best version of myself and I can bring out that inner-supermodel. That inner x-factor.' That's what we have to bring out of all of us. And I have faked it 'til I've made it and ... the one thing I've done along the way is I've learned and I've looked and I've copied and I've read and I've listened, and that's ultimately why I wrote the book, because people always go, 'Oh, you were born that way,' and I got so tired of hearing that.
AP: You write that taking care of yourself is more about respecting yourself than anything else.
Sims: You have to respect yourself, you have to challenge yourself and you have to be the best version of yourself. If you look good, you feel good.
AP: You're expecting your second child, but you've been honest about gaining a lot of weight during your first pregnancy (with son Brooks). Was the weight hard to lose?
Sims: I gained 74 pounds in my last pregnancy. I was 204. I couldn't even see my belly. I ended up having a thyroid condition that they didn't know about it. But it doesn't matter, I still had to lose the 80 pounds. It took me 15 months.
AP: You devote a chapter to finding love, which you say you've had problems with.
Sims: I worked with a really good therapist a few years ago. Her name is Mary Goldenson and she wrote this amazing book. I was really co-dependent. I couldn't get out of a relationship, and I was just stuck, and she made me read ... one of her books called, 'It's Time: No One's Coming to Save You.' And I needed someone to hold me accountable, and the person I needed to hold me accountable was me, and I needed to stop saying, 'OK, I'm gonna do this later, and if this happens then I'm gonna do this.' Like what is happening now? And she told me to get grateful and she told me very hard things that I didn't want to hear. 'Really, you think you're gonna change someone?' ... It was tough and I cried. ... We weren't going to write (about it but) it was one of the best chapters.
