Effects of beta-hydroxybutyrate administration on MK-801-induced schizophrenia-like behaviour in mice.

Rationale: Impaired cerebral glucose metabolism is a core pathological feature of schizophrenia. We recently demonstrated that a ketogenic diet, causing a shift from glycolysis to ketosis, normalized schizophrenia-like behaviours in an acute N-methyl-D-aspartate (NMDA) receptor antagonist model of the illness. Ketogenic diet produces the ketone body, β-hydroxybutyrate (BHB), which may serve as an alternative fuel source in its own right without a strict dietary regime.

Health risk behaviours and allostatic load: A systematic review.

Health risk behaviours (HRB) across the lifespan have been associated with higher cumulative physiological burden as measured by allostatic load (AL). This study examines the contribution of HRB and their effects on multisystem biological risk associated with morbidity and early mortality. We systematically reviewed the literature to assess the links between HRB and AL.
