Twenty-four-hour blood glucose profile. Time course of energy expenditure for (A) ordinary (19:00) and late evening meal (22:30) [7], and (B) skipping breakfast [9], as assessed by whole-room indirect calorimetry. Bedtime (23:00) and wake-up time (6:00) were identical in the two studies. The 24 h energy intake within each study was matched (i.e., the caloric intake of lunch and dinner was increased to compensate for the skipped breakfast). The gray area indicates sleep time, and bedtime (23:00) is shown in vertical rows. Partially modified from [7,9].
