Spatiotemporal profile of altered neural reactivity to food images in obesity: Reward system is altered automatically and predicts efficacy of weight loss intervention.

However, our exploratory analysis revealed that most brain regions and latencies that were affected in obesity in response to high-calorie food stimuli, including the early reward system activations, were qualitatively similarly affected also in response to low-calorie food images, even though the differences in many cases did not reach statistical significance.
