Brief Summary
This study will assess whether weight loss induced through diet and physical activity can change neural responses to high- and low-calorie food images. In addition, it will evaluate whether weight loss can improve neural function when performing the N-back task, a measure of working memory. Findings will address notable gaps in the literature by testing whether a scalable weight loss intervention can help protect and improve neurocognitive functioning and brain health in individuals with obesity. This study will also provide important information about the effects of weight loss on neuroplasticity in brain regions crucial for memory and cognitive functioning, which will help to inform future interventions aimed at promoting brain health.

Outcome Measures
Primary Outcomes (8)
Blood Oxygen Level-dependent (BOLD) Response to High-calorie Foods Cues Minus Neutral Objects in Left Anterior Cingulate Cortex
Changes in BOLD fMRI response to high-calorie food images
Change from baseline to 16 weeks
Reward-based Eating
Changes in scores on the Reward-Based Eating Drive Scale; range of 0-52; higher scores indicate higher reward-related eating
Change from baseline to 16 weeks
Food Cravings- Trait (Lack of Control Over Eating)
Changes in scores on the Food Cravings Questionnaire- Trait (lack of control over eating), range=6-36, higher scores indicate greater cravings
Change from baseline to 16 weeks
Food Preference
Changes in scores on the Leeds Food Preference Questionnaire
Change from baseline to 16 weeks
Eating Behaviors
Changes in scores on the Eating Behaviors Questionnaire (liking for high-calorie foods); visual analog scores ranging from 0-100 with higher scores indicating a worse outcome
Change from baseline to 16 weeks
Hippocampal Volume
Change in hippocampal volume
Change from baseline to 16 weeks
BOLD fMRI Response to the N-back Task
Changes in BOLD fMRI response to the N-back task
Change from baseline to 16 weeks
Eating Behaviors (Low-calorie Foods)
Changes in scores on the Eating Behaviors Questionnaire (liking for low-calorie foods); visual analog scores ranging from 0-100 with higher scores indicating a better outcome
Change from baseline to 16 weeks
Secondary Outcomes (4)
N-back Behavioral Performance
Change from baseline to 16 weeks
Percent Weight
Change from baseline to 16 weeks
Eating Behavior
Change from baseline to 16 weeks
Power of Food
Change from baseline to 16 weeks
Study Arms (2)
WW (formerly Weight Watchers)
EXPERIMENTAL16-weeks of the group-based WW program
Waitlist Control
OTHER16-weeks on waitlist then participants will be provided with 16-weeks of the group-based WW program
Interventions
The WW intervention will consist of weekly group workshops for 16 weeks with WW Coaches and Guides.
The waitlist group will have a 16-week waitlist period. After the waitlist period, they will be offered the WW intervention
