Hey Dana!
I do WW too, but I eat more protein and fat than the strict guidelines of the program recommend (basically instead of low fat, I eat what would probably be considered moderate fat; but I do try to choose lower fat, high quality protein and soy products for my protein needs).
I also try to choose at least 5 servings of low carb veggies every day (in at least 4 or 5 different colors) and cut back on high carb foods (basically processed white flour and sugar). As Peachie has said: "Fiber is my friend!"
I do eat some high carb veggies, fruits, and milk -- which is a no-no on some low carb plans...but I try to keep those to a couple of servings a day.
(note the emphasis on "try"
! )
Read the literature, but keep in mind that there are a lot of voices out there wanting you to buy THEIR plan. I think it's been really important for me to read but also become more aware of how my specific body reacts to certain foods. For example, for me -- pasta is ALWAYS a set up for overeating, but a baked potato isn't. The fact that we're all individuals is what makes this thing so challenging.
More and more information is coming out in support of the low carb alternatives -- and for me it has been invaluable in reprogramming my "low fat is better" mentality (we can't forget that WW makes a pretty penny selling us low fat, high carb, processed foods). But what seems to work best for me as far as energy and minimizing my obsession w/food is a balanced approach -- thinking about the 4 food groups at every meal and trying to get in at least 3...but eating an ounce or two extra of meat at each meal, putting a pat of Smart Balance on my high fiber bread...that kind of thing.
Hope this helps!

ps My WW leader confessed to me the other day that she is certain that she would never have kept her weight off if she hadn't upped her protein intake!
