Want to score a slimmer bod without spending hours and hours at the gym?

Celebs like Jennifer Hudson and Eva Longoria keep their diets in check with meal plans like Weight Watchers and the Sunfare meal delivery service.

"It counts for you!" Longoria says of her preferred way to snag meals and snacks on the go. A Weight Watchers spokesperson, Hudson still enjoys her favorite sushi and stays within her daily limit of points, which are calculated using a food's protein, carbs, fat and fiber content.

"I'm prouder of my weight loss than my Oscar!" the 80 pounds-slimmer former American Idol contestant enthuses.
