I've always struggled with weight too, did WW online a few years ago and lost 35 pounds but gained it all back. I just joined
http://www.sparkpeople.com It's free and very much like WW but you track calories and nutrients, instead of points.
There's all sorts of resources including recipes, exercise plans, message boards. As everyone else has said, it has to be a lifestyle change.
I've also been reading this book, which has been really helpful.

Good luck to everyone on their weight loss journey!
