According to the “old” Weight Watchers point system, one medium banana is worth two points. A little or medium banana has no points under the PointsPlus system.
In 2010, Weight Watchers changed its diet plan to use the PointsPlus system. The new system is based on fibre, fat, carbohydrates, and protein, whereas the old system was based on fibre, fat, and calories.
This is the fundamental distinction between the old and new systems. In 2012, the system underwent yet another modification to incorporate protein, fibre, fat, and carbs into its computations. Notably, the majority of fruits—including apples, mangoes, oranges, pears, peaches, and watermelons—are zero points under the new points system.
