I know people who have had good results with WW too. I've tried it a few times but I am a *terrible* program person. It did give me a better reality check on what was too much (even healthy foods can add weight, duh!). I love their cookbooks. I thought they would be old-school, and some of them are, but there are some absolutely delicious meals too, that I would choose to serve guests even if they weren't low calorie, like maple-crusted chicken breasts and prawn stir-fry with ginger, garlic, sesame seeds, and coconut.

Where I usually get caught up is using up most of my WW points during the day, then working out (or not) and overeating at night.

My tactic now is based on a friend's trip to a Vipassana retreat, where they had fruit and tea for din din. My partner and I have been doing that for a few weeks and lost a few pounds each.
We don't overeat during the day, and tea and fruit at night is a no brainer. That gets to be the ritual (with exceptions, of course) and we don't miss other stuff. Some substitutions have been veggie soup or a lowfat/nondairy fruit smoothie. We're sleeping better, my partner's nighttime digestive probs are gone, and we wake up not much hungrier, if at all, than if we'd eaten the night before. Even if we don't lose a bunch of weight doing this, it feels like a healthy way to be.
