The purpose of this research study is to see how the timing of eating impacts participants sleep and how the body responds to sugar.
This research study is aimed to answer how the timing of eating impacts participants sleep and how the body responds to sugar. Participants must be healthy and between the ages of 18-65 to join . This research study will take 2 weeks of outpatient monitoring, and 2 different nights staying in the Sleep and Metabolism Lab. There are some risks to participating in this study, like hunger, skin irritation, discomfort with blood draws, and uncomfortableness while being observed. The investigators hope that this research will benefit the knowledge learned about circadian rhythms and metabolic disease and how the timing of eating affects these things.
