Summary
Introduction: Obesity is linked to altered activation in reward and control brain cir-cuitry; however, the associated brain activity related to successful or unsuccessful weight loss (WL) is unclear.
Methods: Adults with obesity (N = 75) completed a baseline functional magnetic res-onance imaging (fMRI) scan before entering a WL intervention (ie,3-month diet and physical activity [PA] program). We conducted an exploratory analysis to identify the contributions of baseline brain activation, adherence behavior patterns, and the asso-ciated connections to WL at the conclusion of a 3-month WL intervention. Food cue-reactivity brain regions were functionally identified using fMRI to index brain activation …
