Diurnal variation in glycaemic response to a low and high glycaemic index mixed meal

摘要

Background: Post-prandial metabolic responses have been reported to be diurnal (Hampton et al., 1996; Ribeiro et al., 1998). Previous research into the impact of this diurnal variation on the glycaemic response to high and low glycaemic index (GI) meals has been inconclusive. This study aimed to investigate diurnal differences in the glycaemic response to meals with high (HGI) or low GI (LGI) in the evening compared to the morning.
