I'm a lifetime WW member from way long ago -- and have gained all the weight back (though it took several years).

The last time I seriously attempted weight loss was using the Zone Diet, and I loved the way I felt on it but eventually started wanting to slip in too many of the things that made me fat to begin with (of course).

A friend of mine managed to combine the two by selecting low-glycemic carbs on WW instead of pasta, popcorn, other stuff they allow. Eating sufficient good proteins and good fats (olives, nuts, avacados instead of fake butter), etc. She has had GREAT results by taking what she knew about food chemistry from the Zone and adapting it to the WW program.

My point is, just because you're doing WW points doesn't mean you have to use their food choices. With some study and/or experimentation you may find foods that last longer. (That's actually what the Zone Diet was based on -- keeping your insulin level throughout the day and avoiding those foods that spike and then drop, leaving you ready to eat everything in sight!)
