Brief Summary: The proposed study uses a novel and rigorous randomized cross-over study design in youth 17-23y with late and non-late chronotype n35 per group to assess the glycemic effect of aligning an oral glucose tolerance test OGTT or first-meal of day to a subjects chronotype Both groups will undergo 2 OGTTs aligned and mis-aligned with chronotype to compare glucose tolerance and insulin sensitivity within-subject primary outcome and between groups Aim 1 Then youth will also undergo two standardized meals aligned and mis-aligned with chronotype while wearing continuous glucose monitoring to compare post-prandial glucose excursions within-subject and between groups Aim 2 A pilot Exploratory Aim 3 n12 per group will investigate delayed melatonin patterns under dim-light as a potential pathophysiologic mechanism behind abnormal glucose tolerance in youth with late chronotype on morning OGTTs
