Weight Watchers waives registration fee

Oscar winner Jennifer Hudson is slimming down with the help of Weight Watchers, and so can you. Weight Watchers -- the elder stateswoman of the weight-loss industry -- is waiving its registration fee if you join by May 29.

The special offer is good for memberships that include attending meetings or the online plan. If you aren't sure you want to commit to joining, sign up for a free, one-week trial of the online plan to test out all the features. At the end of the free trial you will be automatically subscribed to a three-month paid plan unless you cancel it. You can also attend a free meeting to check it out.
