I've seen a lot of questions about previous WW programs, so I did a little digging and this is what I came up with....
1972 - Weight Watchers Program Handbook for Ladies
1989 - Exchange Program
1997 - 1-2-3 Success - The First Points Program
2001 Winning Points - Redesign of the 1-2-3 Plan
2004 Turn Around - with Flex and Core. New Core Plan - Later to be known as Simply Filling - Allows for a list of foods to be eaten 'until satisfied' - without counting points. (Some concepts similar to South Beach Diet) Activity Points can be earned, but used that day only - no banking of points.
2008 Momentum - Points Program that takes filling foods from the Core concept and combines it with the Points program. Core has been eliminated. Simply Filling is the new name for Core. You can earn 35 weekly points and activity points based on weight, duration and intensity of exercise. Activity Points can now be banked weekly. There is a range of 18-37 daily points.
2010 Points Plus - Points Plus and Simply Filling Technique (Simply Filling is similar to previous Core plan) - There are new daily target ranges, new point values, all the points are now referred to as Points Plus. Points are now calculated with 4 values instead of 3 - carbs, fat, fiber, and protein. Daily point range is now 26-71 daily points, with 49 weekly points - A substantial increase, however, most food now also has a higher point value.
Simply Filling Technique (SFT) also gets 49 weekly points to be used for non SFT foods. Both plans earn Activity Points, which can be banked weekly.
2012 - 360 Points Plus and Simply Filling with the addition of Behavioral and Environmental changes. No changes to food values!
2015-2017 Smart Points Beyond the Scale - SmartPoints® are calculated using calories, saturated fat, sugar, and protein. Foods with higher amounts of sugar and saturated fats have higher SmartPoints® values. Foods with higher amounts of lean protein have lower SmartPoints® values. Many lean proteins like chicken and seafood are now lower in points and sweet treats like muffins, cookies and sugar sweetened beverages are higher. And about 40 percent of foods have stayed the same. The SmartPoints® plan is based on the latest in nutritional science, nudging you toward a pattern, not only of weight loss, but of healthier eating with more fruits, vegetables and lean protein, and less sugar and saturated fat, With SmartPoints®, you can not only pinpoint the choices that help you lose weight, but you shift to a healthier pattern of eating overall
