Consumption of low Glycemic Index (GI) foods has been shown to not only attenuate blood glucose response during the postprandial period immediately following a meal but to have also positive metabolic effects at the subsequent meal, known as the "second-meal effect" by reducing glucose excursion beyond actual meal. The relative importance of the timing of the glycemic load variation (e.g., breakfast or dinner) on the overall, 24h, glycemic control has not been investigated in detail.
