Differences between groups in changes over time (6 months to baseline) in blood oxygen-level-dependent (BOLD) signal b-values (max-voxels) for high-calorie (HC) and low-calorie (LC) foods minus non-food (NF) paired images; also, changes in relative signal strength for HC and LC (delta values for HC-NF minus LC-NF). Significance is denoted with *P<0.05 or **P<0.01, and relevant Cohen’s d-values are given as numerals.
