Interaction of melatonin receptor 1B (MTNR1B) genotype and type of breakfast (protein-enriched v carbohydrate-rich) on postprandial glucose response: a randomised crossover trial.

Abstract excerpt

BACKGROUND: The risk allele (G) of MTNR1B rs10830963 has been associated with impaired glucose tolerance, increased fasting glucose and type 2 diabetes (T2D). Late evening eating, when endogenous melatonin levels are elevated, is associated with impaired glucose control in MTNR1B risk carriers. Endogenous melatonin levels remain elevated into the morning so may influence glucose response to breakfast. OBJECTIVE:...
