Jennifer Hudson Reveals How She Became a Size 6

A month following the announcement of her endorsement deal with Weight Watchers, Academy Award winner Jennifer Hudson has already witnessed positive results from the company's products. In the new issue of People magazine, Hudson says that she's "in the best shape" of her life, slimming down from a size 16 to a slender size 6.

The actress's newfound weight loss is also due in part to her forthcoming role as Nelson Mandela's ex-wife in the biopic 'Winnie.' The 28-year-old said she was determined to lose her post-pregnancy weight, noting that she would do "whatever it takes to morph into a character."

"With Weight Watchers, I am enjoying the weight loss because I'm doing it the right way. I feel empowered with what I've learned," she told the weekly just last month. "Everything from portion control to what foods will help keep me satisfied -- it's a lifestyle change, not a diet."

With production set to begin in South Africa on May 31, Hudson's Weight Watchers counselor, Liz Josefsberg, is more than optimistic that the actress will stick to her diet regimen.

"She will need to investigate every new product on this new continent," Josefsberg explained to People. "I am not the least bit worried about Jennifer. She is an amazing and resilient personality who will be just fine in her surroundings."

On the heels of her breakout role in 'Dreamgirls,' the former 'American Idol' castoff graced the covers of magazine such as Ebony, Essence and Vogue as the new face of big and beautiful. Now, she's on People looking slim and trim.
