I used ediets years ago when it was still free.
Try sparkpeople, it will give you a diet meal plan to follow and its free. All the support you need is there. Groups, forums, blogs, make friends, food journal, exercise journal, and even free exercise videos on the site. I know quite a few people personally who have used it and lost a great deal amount of weight. I had to get off there because I spent more time chit-chatting to fellow sparkers than I did working. LOL They have groups for every type of weight loss plan that you can think of.
