WW is Bullshit

We have been doing WW for a few months now and I am stuck at a loss of 5 lbs.  I want to restrict so badly.  This is Leah btw.  Why can't I just starve?  They say it is because we have to keep our metabolism up.  We were exercising but technical difficulties with the car got in the way of that.  I don't know how long I can do this WW thing without restricting.
