Predictors of Behavioral Obesity Treatment Outcomes
Trial Parameters
Brief Summary
Socioceconomically disadvantaged individuals typically have poor outcomes in behavioral weight loss interventions, but the reasons for this are unknown. This project will characterize the mechanisms through which adverse daily experiences and present bias -- a cognitive adaptation to harsh and unpredictable environments -- account for disparities in weight loss outcomes.
