Circadian Misalignment

Aligning feeding periods with the body's natural active phase offers metabolic protection against circadian misalignment. Misalignment between the central circadian clock and daily behaviors typical of night workers impairs glucose tolerance. Food timing synchronizes peripheral clocks in multiple metabolic organs. Consistent late eating can place peripheral clocks on a different schedule than the central brain clock. Circadian disruption directly produces adverse glycemic effects. Circadian desynchrony can impair hormones, insulin sensitivity, triglycerides, fat oxidation, and adiposity. Repeated late weekend meals can disrupt peripheral clocks for more than one day.
