What Stacey is talking about is your Set Point. As in, what your already doing is keeping you where your at. Your body has become accustomed to that. So in order to lose you need to do More. Thats the hard part, finding out what/where your More is and doing it. But I think you get that part. Heres what you originally asked for...
Calculating Activity Points
Here are some formulas that may help you calculate your exercise points:
Light Activity (you can feel it a bit but not too stressful):
Weight x Minutes x .000232 = Activity Points
Moderate Activity (you can feel your heart rate rise a bit and lightly perspite):
Weight x Minutes x .000327 = Activity Points
High Activity (heart rate rises and you break a good sweat):
Weight x Minutes x .0008077 = Activity Points
Being that this is the Weight Watchers section and your new to this forum.. A lil navigational help

if you use the "Search" function at the top and enter in whatever it is your looking for or asking about, a ton of threads will come up and you can read, research till your hearts content.
Good Luck on your Journey!!
