Classic Weight Watchers Formulas

As I am trying to work on losing weight again, I ran into an old formula chart used to compute how many Weight Watchers Points you were allowed and how to determine how many points food items counted as.  This is using the older system from around the late 2000s.  I remember they modified it sometime around 2010, but I never learned how to compute the new formulas.  I found these formulas on various websites and compared them to my information I got for my Weight Watchers program and they did match up.

Daily Point Allowance: Add to get Daily value

• Gender
• Male - 8
• Female - 2
• Nursing Female - 12
• Age
• 17-26 - 4
• 27-37 - 3
• 38-47 - 2
• 48-58 - 1
• >58 - 0
• Weight
• 1st 2 digits of your weight in pounds  (245 pounds -> 24 points)
• Height
• < 5'1 - 0
• 5'1-5'10 - 1
• >5'10 - 2
• Predominate Daily Activity
• Sitting - 0
• Occasional Sitting - 2
• Mostly Walking - 4
• Physically Hard Work - 6

Weekly Point Allowance: 35 (optional points that can be used any time during the week for overages or splurging on a treat)

Food Point Value:
(Calories/50) + (Fat/12) - (Minimum(Dietary Fiber,4)/5)

Note that you can only use up to 4 grams of Dietary Fiber in the calculation.  So if you have 2g of fiber, you would use 2/5.  If you had 6g of fiber, you would use the 4/5 value since it is capped at 4g.

Update:
Activity Points
I just discovered this information (July 2017).
Activity points are deducted from your daily accumulated points.  You need to use the following formula:
Weight (lbs) x Duration (min) x Intensity Factor

Intensity Factor:

• Low 
• 0.0002332 
• Not sweating from activity, can carry conversation
• Medium
• 0.0003270
• Sweat after about 10m of activity. Can say few sentences but not full conversation.
• High
• 0.0008077
• Sweating after about 3-5m of activity.  Can say few words as a time, but no much more
