Schematic of the 5-day inpatient randomized, crossover research design. Four participants completed all four experimental conditions (Normal Sleep/Normal Meal, Normal Sleep/Late Meal, Late Sleep/Normal Meal, Late Sleep/Late Meal) including neuroimaging. Black bars represent sleep opportunities (8 hours in bed; 0000 to 0800h for Normal Sleep, 0330–1130h for Late Sleep). Meal times are indicated with initial (B, breakfast; L, lunch; D, dinner; S, snack; gray font denotes weight-maintenance meals; bold font denotes ad libitum meals). Normal mealtimes occur 1, 5, 11 and 12.5 hours after awakening; late mealtimes occur 4.5, 8.5, 14.5, and 16 hours after awakening. The timing of the fMRI scan visit during which resting-state neuroimaging data were collected was approximately 1 hour before the 4th dinnertime and is represented by a gray brain schematic inside a black box.
