I agree with a couple of things said first don't over estimate your
points,  I was giving myself 13 points for  strength training for 30
mins + 30 mins high intesity cardio. After talking with my weight
watcher leaders I realised , I should be getting  about  3 points for
the strengh training = moderate for 30 mins. Then  6 points for 30
mins high intesity cardio.
        Second point I was eating almost all  of my points which were
inflated to start with.  Also I was dependant on my exercise points
and planned my meals including them. And I couldn't figure out why I
was "plateauing" out at 49 pounds lost I could't break 50 pounds.  My
leaders advised only eat 3 or 4 points from the excercise points. When
I exercise more my body sometimes needs more calories because the
metabolism is burning strong. Now I rarely go beyond my regular points
and I am down 56 pounds as of  10/16.
Talk to your leader about how you are doing  calculating your points.
I was advised if I could talk or read a book , I was not  getting a
high intesity workout.
