A new dress size (from size 16 to size 6) and a healthier outlook, singer/ actress Jennifer Hudson has a lot to celebrate these days, and the Oscar winner isn’t keeping the secrets to her new healthy lifestyle to herself. As part of her work as a spokesperson for Weight Watchers, she is leading the Lose For Good initiative, which teaches families how to prepare low-cost and healthy meals in an effort to fight hunger and obesity.   And if you didn’t already have a good reason for losing weight, J-Hud is asking you to drop it for a great cause. Between September 3rd and October 23rd Weight Watchers members and online subscribers who drop a pound will help the company raise $1 million to hunger-fighting organizations, Share Our Strength and Action Against Hunger. Log on to Weight Watchers and drop those pounds for a cause.
