A new study, published in Journal of Metabolism: Clinical and Experimental (October 2017) by Danish Diabetes Academy Post Doc Esben Søndergaard, shows similar postprandial VLDL-TG metabolism in men with and without type 2 diabetes.
SIMILAR POSTPRANDIAL SUPPRESSION OF VLDL-TG SECRETION
Men with type 2 diabetes have similar postprandial suppression of VLDL-TG secretion. Therefore, the abnormalities in postprandial VLDL-TG metabolism is a consequence of obesity/insulin resistance and not type 2 diabetes in itself. Instead, the excessive postprandial lipemia in type 2 diabetes is a consequence of more plasma chylomicrons instead of VLDL particles, most likely due to increased chylomicron appearance from enterocytes.
SIMILAR VLDL-TG STORAGE IN ADIPOSE TISSUE
A reduced capacity to store excess calories in adipose tissue lipid may lead to ectopic fat storage, causing insulin resistance and type 2 diabetes. However, in this study, there was no difference in the ability to VLDL-TG after a high fat meal despite excess postprandial lipemia.
