In November 2010, Weight Watchers announced that the Point system was being replaced by a new PointsPlus system. The old system used calculations based on calories, fat, and fiber content. The new PointsPlus system replaced calorie calculations with protein and carbohydrates.
Carbs ~ Protein ~ Fat ~ Fiber = Points+
This calculator based on Weight Watchers "Points Plus" system. Also know as Points+, Pts+, PlusPoints, or PointsPlus.
*Calculator provides estimated points and may not be accurate, it is not an official Weight Watchers calculator.
The formula in use is an empirical match obtained from public sources.
