There has been some previous studies suggesting that particularly high-intensity exercise can blunt appetite and reduce food intake. New  study might have shed light in this respect. According to a new study exercise-induced elevation in brain temperature namely reduces food intake, and may thus contribute to body weight regulation.

On the other hand, we have also previously shown that food high in sugar and/or fat changes gene expression in the brain in those genes that regulate appetite. Thus, both exercise and food matter in the regulation of food intake and body weight regulation.
