Weight Watchers have overhauled their points system and come up with a completely new program – called Points Plus.
The previous Points formula (started in 1997) took into account Calories, Fiber grams and Fat grams. The PointsPlus formula uses Protein, Carbohydrate, Fiber, and Fat grams.
Weight Watchers have spent a number of years testing the new program (at the Medical University of South Carolina among other places). According to Weight Watchers the trials resulted in “an improvement in behaviors that help people maintain weight loss and a reduction in the desire to eat when there’s no physical hunger or need for food.”
Critics of the previous Points formula claimed that it did not accurately differentiate between more nutritionally dense foods, and “empty calories”. This is due to the heavy weighting of Calories over other nutrient measures.
