Regional brain response to visual food cues is a marker of satiety that predicts food choice.

ABSTRACT:

Background

Neuronal processes that underlie the subjective experience of satiety after a meal are not well defined.

Objective

We investigated how satiety alters the perception of and neural response to visual food cues.

Design

Normal-weight participants (10 men, 13 women) underwent 2 fMRI scans while viewing images of high-calorie food that was previously rated as incompatible with weight loss and "fattening" and low-calorie, "nonfattening" food. After a fasting fMRI scan, participants ate a standardized breakfast and underwent reimaging at a randomly assigned time 15-300 min after breakfast to vary the degree of satiety. Measures of subjective appetite, food appeal, and ad libitum food intake (measured after the second fMRI scan) were correlated with activation by "f
