WeightWatchers

WeightWatchers is still used to lose weight, but it now emphasizes encouraging healthy living and enhancing general wellbeing. This includes using a comprehensive strategy to encourage participants to eat better and move more. Support through the WW app, expert-led online and in-person workshops to deliver useful tools and behavior-change approaches for assistance along the road are the program's mainstays.

The WW changed its Points® system in November 2021 to take added sugar, unsaturated fat, and fiber into account in addition to other nutrients. Behavior modification, behavioral economics, clinical research, nutrition, and exercise science are areas of expertise for WW scientists. Gary Foster, the chief scientific officer for WW and author of "The Shift: 7 Key Mindset Adjustments for Sustainable Weight Reduction," serves as the group's leader.
