About this trial

This study will test whether biological sex influences how the body responds to circadian misalignment-a mismatch between the internal body clock and the timing of sleep and eating (as can occur with shift work or jet lag). Researchers will examine how circadian misalignment affects appetite regulation (hunger/fullness) and glucose metabolism (blood sugar control), and whether these effects differ between females and males. Findings may help inform more personalized shift work schedules and targeted strategies to reduce metabolic health risks and sex-related differences in clinical care.
