I did WW Online a couple years ago and lost the 20 lbs. that wouldn't budge before. I really, really liked it. I was never hungry. You learn the low/no point food options and fill up with those (for instance, fruit is a good one), in addition to regular foods.
It wasn't that hard. I learned to plan before going out to eat. I'd research menu nutrition info before going to a restaurant. I even lost weight on a cruise and that was with having dessert every night! Seriously. I just made sure I used the gym on the ship every day, in addition to all of the walking we did while on shore.
One of the best things is that you don't have to eliminate any foods. So, if your weakness is chocolate, for instance, you can still have some. You just learn the right portion and to budget your points for a little every day (or however frequent you want an item).
Give it a try!
