I am in maintenance now but when I was still losing I absolutely needed to use both my wp(s) and my ap(s). My metabolism would slow when I didn't. I would still lose, but would gain when I inevitably did use them. And after all, that is what the WW lifestyle is all about.
Ellie Krieger has a great recipe for fish sticks by the way. Google it on Food Network. I subbed tilapia for whatever she used (I think it was cod)
