['The aim of this work was to investigate hepatic lipid metabolic processes possibly involved in the reduction of liver fat content (LF) observed in patients with type 2 diabetes after an isoenergetic diet enriched in monounsaturated fatty acids (MUFAs).', 'This is an ancillary analysis of a published study. In a parallel-group design, 30 men and eight women, aged 35-70\xa0years, with type 2 diabetes and whose blood glucose was controlled satisfactorily (HbA', 'LF was reduced by 30% after the MUFA diet, as already reported. Postprandial β-hydroxybutyrate incremental AUC (iAUC) was significantly less suppressed after the MUFA diet (n\u2009=\u200916) (-2504\u2009±\u20094488\xa0μmol/l\u2009×\u2009360\xa0min vs baseline -9021\u2009±\u20096489\xa0μmol/l\u2009×\u2009360\xa0min) while it was unchanged after the CHO/fibre diet (n\u2009=\u200917) (-8168\u2009±\u20099827\xa0μmol/l\u2009×\u2009360\xa0min vs baseline -7206\u2009±\u200910,005\xa0μmol/l\u2009×\u2009360\xa0min, p\u2009=\u20090.962) (mean\u2009±\u2009SD, p\u2009=\u20090.043). In the participants assigned to the MUFA diet, the change in postprandial β-hydroxybutyrate iAUC was inversely associated with the change in LF (r\u2009=\u2009-0.642, p\u2009=\u20090.010). DNL and SCD-1 indirect indices did not change significantly after either of the dietary interventions.'] Is reduction in liver fat by dietary MUFA in type 2 diabetes helped by enhanced hepatic fat oxidation?
