How do you know how many points you can have a day? I am not officially a part of Weight watchers but am interested to see how it works..... Thank-you

Depends on your current weight:
Less than 150 pounds - 20 points
150-174lbs - 22
175-199lbs - 24
200-224lbs - 26
225-249lbs - 28
250-274lbs - 30
275-299lbs - 31
300-324lbs - 32
325-349lbs - 33
350lbs + - 34

In addition, there are 35 optional points per week that you can use for a special occasion or not at all.
