Jennifer Hudson's Startling 80 Pound Weight Loss; Here's How

Jennifer Hudson had jaws dropping when she showed up looking skinner than ever in a form-fitting black velvet Dolce & Gabbana dress at the Keep a Child Alive’s 7th Annual Black Ball in New York Sept. 30, 2010. Here’s how she did it.

Hudson, 29, has shed 80 pounds in the past 12 months thanks to Weight Watchers and working out five days a week with celebrity trainer Harley Pasternak.

Jennifer, who slimmed down from a size 16 to a 6, revealed that she wanted to lose weight to set a good example for her son, David, who was born in August 2009.

“I feel like I’ve conquered the world,” Hudson recently told ABC’s “Good Morning America.”

“Her middle, thighs and butt are more toned than ever. She’s excited about her new body,” said Pasternak.

Jennifer, who has been heavy all her life, attributes her dramatic weight loss to portion control and circuit-training workouts.

Rather than starving and binging, Hudson eats what she wants (within limits) and has adjusted her attitude toward dieting so it’s a long-term solution, rather than a short-term goal.

In fact, Jennifer has lost so much weight that fans barely recognize her now.

“I was in an airport and the girl working the X-ray machine said, ‘Anybody ever tell you you look like Jennifer Hudson?’

“I was like, ‘I am.’ And she said, ‘No you’re not. Because you’re skinny! Jennifer Hudson ain’t skinny!”

Well, now she is.
