I've been doing WW for several months with some success. I'm just now trying Alli. I use the WW etools. I can tell you that the WW food log is MUCH better than Alli's. Maybe I'm just not used to it yet, but very few things I search for are there. I've had to create foods for almost everything I eat.
Just from reading the posts here, I'm concerned about reaching the fat goal. This is A LOT more fat than I'm used to. It will be interesting to see if meeting the Alli goal works with WW. I'm thinking it's going to blow my points sky high.
