Interesting question. I revised my original WW goal up by 3 lbs. when it was clear I could not maintain at my 1st choice. Today, in talking with my leader, I may revise it up again. I lost 1.2 lbs. this week after 3 consecutive weeks of gainin 2+ lbs./week.

I am in a good groove of exercising 4 times/week, tracking food, making healthy choices, drinking a lot of water, feeling good about what I eat.
So I think I will see what I weigh at the next 2 meetings. If I stay where I am now, that is probably going to become my goal. It needs to be a weight I can maintain without a huge struggle.
One drawback I have found with WW (tho. overall the program helped me tremendously) is the focus on a single number. I feel my health has improved, I look great, I'm exercising and I am much more in tune with my body and what it needs. But all I track at WW is the number on the scale--it's a very limiting and limited measure of things.
