β-Hydroxybutyrate (BHB) is an abundant ketone body. To date, all known pathways of BHB metabolism involve the interconversion of BHB and primary energy intermediates. Moya-Garzon et al. identified a previously undescribed BHB secondary metabolic pathway via CNDP2-dependent enzymatic conjugation of BHB and free amino acids.

Orexigenic appetitive processing relies on the integration of sensory, interoceptive and hormonal signals to govern consummatory behaviors. Dysregulation of this process leads to maladaptive eating behavior such as binge eating and is associated with obesity. This circuit, however, was elusive in humans --- until now.

Using an interventional study in healthy, normal-weight participants, Thanarajah et al. demonstrate that, independent of body weight gain and alterations in metabolic markers, exposure to high-fat/high-sugar food: (i) reduces preferences for low-fat food, (ii) plays a critical role in up-regulating brain responses to anticipation and consumption of highly palatable, energy-dense food, and (iii) has a generalized effect on the neuronal encoding of prediction errors in the context of associative learning and independent of food rewards. Taken together, repeated consumption of high-fat/high-sugar relative to isocaloric low-fat/low-sugar food, and in the absence of changes in body weight or metabolic state, can rewire brain circuits and thereby induce neurobehavioral adaptations. Hence, changing the food environment and reducing the availability of energy-dense high-fat/high-sugar food items is pivotal to combating the obesity pandemic.
