Food odour recognition is involved in the food anticipatory response. A study in Nature Metabolism describes how the olfactory system differentially regulates metabolic adaptations depending on energy availability. These effects are mediated by a brain circuit involving the melanocortin system that controls systemic lipid utilization via the sympathetic nervous system.
