Several factors including increased production of ketone bodies in a dose-dependent manner [6], secretion of incretins such as peptide YY (PYY) [5], and/or potentiation of glucose-stimulated insulin secretion [9,10] may explain the beneficial influence of dietary MCT in enhancing glucose tolerance in individuals with T2D [7,8]. The gene discussed is GCG; the disease is type 2 diabetes mellitus.
