Under the “old” Weight Watchers point system, a medium banana was worth two points. A small or medium banana is worth 0 points in the PointsPlus system.
In 2010, Weight Watchers changed its diet plan to use the PointsPlus system. The main difference between the old and new systems is that the new one is based on fibre, fat, carbohydrates, and protein, while the old one was based on fibre, fat, and calories. In 2012, the system was changed again to take protein, fibre, fat, and carbohydrates into account. Under the new points system, most fruits, like apples, mangoes, oranges, pears, peaches, and watermelons, are worth zero points.
