Whole blood D-β-HB concentrations were measured with a Nova Vet ketone meter (Nova Biomedical, Waltham, MA) from a tail nick. Animals had food withheld for 4 h and refed for 4 h before testing at the start of the dark cycle. This measure was performed during week 6 of the experimental phase of the study. AcAc concentrations are not measurable by the ketone meter and are not available.
