Now, the natural food chef juggles several roles — TV star, businesswoman, author, fitness guru, and soon-to-be talk show host — but it's her personal life with husband Jason Hoppy and daughter Bryn, 2, that she finds most rewarding.

But as for what's literally on her plate, the 37-year-old recently shared her healthy eating habits and workout strategies with Self.com.

Rachael Ray talks to omg! about food, family, and fitness. (Mike Coppola/Getty Images)It was those famous "30 Minute Meals" — always focused on fresh ingredients — that helped Rachael Ray become a household name. But despite the celebrity chef's penchant for veggies, her "everything in moderation" mantra (which includes burgers and mac and cheese too), and her push to use good-for-your-heart E.V.O.O. (her now-famous abbreviation for extra virgin olive oil), Ray admits one big piece of a healthy lifestyle was missing for her for a very long time.

Janet Jackson has been candid about her lifelong struggle with weight, but — as you can see in this new photo from her Nutrisystem ad campaign — she appears to be winning the battle.

If you're a "Dancing With the Stars" fan, you know that the pros who spend their days rehearsing their moves and their nights boogying in front of millions have to be in super shape to do the job.

"Since a lot of dance movements begin and end with the legs, there is a lot of attention drawn to them. The more sculpted and toned the better!"

Looking to get your own killer stems? Look no further than the Cheryl's personal leg workout, which includes three moves the dancer does every day. "Start by doing ten minutes and, each day, add time to your routine to build stamina and endurance," says Burke. "You'll have shapely legs in no time!"

Alison Sweeney sizzles on the cover of Shape magazine. Alison Sweeney probably never imagined she'd end up posing on the cover of a national magazine in a bikini. After all, the now 35-year-old struggled with her weight publicly after being cast in the soap opera "Days of Our Lives" as a teenager.

"Most women go through phases of looking in the mirror and not being happy with what they see," the "Biggest Loser" hosts says in the April issue of Shape magazine, which features the mom of two posing in a string bikini — and showing off some truly fab abs — on the cover. "I was letting it dictate my entire life — I felt disappointed when I went clothes shopping and guilty about everything I put in my mouth.

What Alison Sweeney Eats Almost Every Day

"He finally, gently, told me, 'I think you're beautiful, but you complain about your body and don't do anything about it. You either have to be happy with who you are or stop eating ice cream. Put up or shut up.' And he was right."
