Doug Lerner reports from Tokyo and St. Louis, and points beyond…

PointsPlus

In November 2010, Weight Watchers announced that its Points system was being replaced by a new PointsPlus system. The old system was based on a calculation based on calories, fat, and fiber content. The new PointsPlus system is based on protein, carbohydrates, fat and fiber.

PointsPlus = max { mathrm{round} left( frac{16}{175}protein + frac{19}{175}carbohydrates + frac{9}{35}fat - frac{2}{25}fiber right) , 0 }

or

PointsPlus = max { mathrm{round} left( frac{protein}{10.9375}p + frac{carbohydrates}{9.2105} + frac{fat}{3.8889} - frac{fiber}{12.5} right) , 0 }

where all units are grams. This formula is an empirical match to the Weight Watchers calculators and may not be exact; Weight Watchers has not published their actual formula.

ProPoints

In the UK during November 2010, Weight Watchers announced that it’s Points system was being replaced by a new ProPoints system. The old system was based on a calculation based on calories and saturated-fat. The new PointsPlus system is based on protein, carbohydrates, fat and fiber.

ProPoints = max { mathrm{round} left( frac{protein}{10.99} + frac{carbohydrates}{9.17} + frac{fat}{3.89} + frac{fibre}{34.48} right) , 0 }

where all input units are grams. This formula is an empirical[11] match to the Weight Watchers calculators and may not be exact; Weight Watchers has not published their actual formula.

This is a matter of public record from U.S. patent filings.

  1. that is the propoints formula but the points plus is a little different because the packaging is different. try wikipedia. it is listed on there

    Thanks. I’ve updated the post. I was wondering why the Points Plus fiber term was positive since fiber is supposed to reduce points. And I can see in the WIkipedia version it is negative. Though it’s still positive in the ProPoints version.

  3. Thanks so much. I was not having any luck finding this is the patents. Do you have the patent number?

    Sorry, I don’t know the patent number. But I grabbed the info off of this Wikipedia page:http://en.wikipedia.org/wiki/Weight_Watchers#Formulas
