The purpose of this pilot study is to explore the benefits of supplementing the WW (formerly Weight Watchers) online program with a cognitive training game (PolyRules!) among adults with overweight or obesity.
This two-arm pilot study will be used to estimate the effect size in weight loss of supplementing the WW (formerly Weight Watchers) online program with gamified inhibitory control training (PolyRules!) among adults with overweight or obesity. Participants ages 18 and older (n=30) will be randomly assigned to one of two study arms: (1) WW (formerly Weight Watchers) only or (2) WW + Gamified inhibitory control training (PolyRules!). All participants will complete demographic, medical history questionnaires and cognitive assessment battery at baseline/enrollment and after completing the 3-month intervention protocol. All interactions with PolyRules! and WW will be passively recorded to monitor the frequency of interaction with WW and PolyRules!.

WW is a structured behavioral weight management program that focuses on diet, physical activity and mindset skills. The dietary approach is based on creating an energy deficit diet to produce weight loss while also being attentive to the quality of the calories. Specifically, the WW program assigns SmartPoints values to foods based on calories, sugar, saturated fat and protein. In addition, particular foods are assigned a points value of zero (0) to encourage a healthier eating pattern (e.g. fruits, vegetables, non-fat yogurt, fish).
In addition to WW, participants will be asked to engage in daily cognitive training using the PolyRules! app for three months. They will be instructed to start with 20-min of daily cognitive training and to progressively increase their training time to 30-min.

BMI at Three Months
BMI will be calculated by aggregating participants' self-reported height in meters and weight in kilograms at baseline and at 3 months. Throughout the study, participants will be asked to self-report their weight through the WW (formerly Weight Watchers) online app. This data will be used to calculate change in BMI.
Time frame: Baseline, 3 months
