Impact of Sleep and Meal Timing on Food Intake Regulation

Summary

This study will test the hypothesis that a late sleep (Ls) and/or late meal (Lm) behavioral pattern, with equal sleep duration, will promote positive energy balance and insulin resistance (IR).

Conditions

• Obesity
• Diabetes Mellitus, Type II
• Cardiovascular Disease

Interventions

BEHAVIORAL

Normal Sleep/ Normal Meal

The subject will be inpatient for 5 days, and sleep between the hours of 0000-0800 h, with meals at 1, 5, 11, and 12.5 (snack) h after awakening every day for 5 days. On night 3, we will insert a catheter in the participant's arm to facilitate multiple blood sampling overnight and the next day. On d 4, a frequently sampled i.v. glucose tolerance test (FSIVGTT) will be performed. A MTT will be performed at the scheduled lunch. At 1 h before dinner, participants will undergo fMRI scanning to assess neuronal responses to food stimuli and to examine functional connectivity with reward circuitry. On d 5, participants will be allowed to determine their own food intake at the scheduled meal and snack times. Participants will be discharged upon awakening on day 6.

BEHAVIORAL

Normal Sleep/ Late Meal

The subject will be inpatient for 5 days and sleep between the hours of 0000-0800 h,with controlled meals at 4.5, 8.5, 14.5, and 16 (snack) h after awakening. On night 3, we will insert a catheter in the participant's arm to facilitate multiple blood sampling overnight and the next day. On d 4, at the scheduled breakfast time, a frequently sampled i.v. glucose tolerance test (FSIVGTT) will be performed. A MTT will be performed at the scheduled lunch. At 1 h before dinner, participants will undergo fMRI scanning to assess neuronal responses to food stimuli and to examine functional connectivity with reward circuitry. On d 5, participants will be allowed to determine their own food intake at the scheduled meal and snack times. Participants will be discharged upon awakening on day 6.

BEHAVIORAL

Late Sleep/ Normal Meal

The subject will be inpatient for 5 days, and sleep between the hours of 0330-1130 h, with controlled meals at 1, 5, 11, and 12.5 (snack) h after awakening. On night 3, we will insert a catheter in the participant's arm to facilitate multiple blood sampling overnight and the next day.
