  • These results strongly support the hypothesis that muscle insulin resistance in aging promotes hyperlipidemia and NAFLD by altering the pattern of postprandial carbohydrate storage away from muscle glycogen and into hepatic DNL. (diabetesjournals.org)
  • In young, normal weight, healthy individuals, muscle insulin resistance has been proposed to be an important predisposing factor for atherogenic dyslipidemia and NAFLD by changing the pattern of energy storage from ingested carbohydrate away from skeletal muscle glycogen synthesis into hepatic de novo lipogenesis (DNL), resulting in an increase in plasma triglyceride (TG) concentrations and increased hepatic TG synthesis ( 3 ). (diabetesjournals.org)
