It's hard to find much body fat in Hollywood these days, but there's a big difference between looking fit and being fit.

That's why I was inspired to pay tribute to three celebs who are more than just a pretty face and skinny bod. These lovely ladies are a true inspiration for their dedication, hard work and commitment to live a healthy lifestyle. Read on for more!

Jennifer Hudson:

The talented actress and singer has said she's prouder of her weight loss than her Oscar - and she should be! By sticking to a strict regimen of portion control and exercise, Hudson shed more than 80 pounds and went from a size 16 to a 6.

Inspiring people all over the world with her weight loss, Hudson continues to show her commitment to living a healthier lifestyle. She recently opened "The Weight Watchers Jennifer Hudson Center" in her hometown of Chicago. Giving inspiration and giving back is what this star does best. A portion of the center's revenue will go to a foundation for families of murder victims Hudson co-founded in honor of her late nephew, Julian King.

The Weight Watchers spokeswoman also just penned an inspirational weight loss memoir (to be released in early January) titled I Got This: How I Changed My Ways and Lost What Weighed Me Down, available for pre-order on Amazon and Barnes & Noble.

Jillian Michaels:

TV's toughest trainer is back and better than ever. Michaels recently expanded her television presence into daytime as co-host on the Emmy award-winning series The Doctors, as well as special contributor to Dr. Phil.

But before she was a huge TV success, Jillian struggled with her own weight. At age 12 she tipped the scales at 175 pounds, and was tired of being "the chubby ugly duckling who ate lunch alone everyday."

Motivated by her own need for personal transformation, the talented trainer has developed the tools to change other lives drastically.

She recently launched Killer Buns & Thighs in September, and her newest DVD project Extreme Shed & Shred will hit Amazon this December.

With a slew of best-selling books, exercise DVDs and a line of weight loss supplements, what I love most about Michaels is that she really seems to care about the success of the people she helps.

Jane Fonda:

This weekend I covered the "Decade of Difference" gala for the Clinton Foundation where I spotted Jane Fonda on the red carpet. I've never seen the 73-year-old in person until now, and all I can say is wow! She looked absolutely amazing in a pair of metallic skinny jeans and shimmery sequined jacket.

The veteran actress, activist and fitness fanatic has released more than 20 exercise videos since 1982, and is a true inspiration for all things healthy.

She recently launched a new book titled Prime Time: Love, health, sex, fitness, friendship, spirit – making the most of all of your life.

The book gives her own perspective on how to better live what she calls "the critical years from 45 and 50, and especially from 60 and beyond."

Fonda also has two more fitness DVDs (Trim, Tone & Flex and Firm & Burn) to be released in December, aimed towards older exercisers or those who are just starting out.

The best part? She'll be presented with the "Shape Your Life Award" by our editors at the end of October for her dedication to good health!
