Abstract

Background Epidemiologic evidence indicates that chronic sleep curtailment increases risk of developing obesity, but the mechanisms behind this relation are largely unknown.Objective We examined the influence of a single night of total sleep deprivation on morning energy expenditures and food intakes in healthy humans.Design According to a balanced crossover design, we examined 14 normal-weight male subjects on 2 occasions during a regular 24-h sleep-wake cycle (including 8 h of nocturnal sleep) and a 24-h period of continuous wakefulness. On the morning after regular sleep and total sleep deprivation, resting and postprandial energy expenditures were assessed by indirect calorimetry, and the free-choice food intake from an opulent buffet was tested in the late afternoon at the end of the experiment. Circulating concentrations of ghrelin, leptin, norepinephrine, cortisol, thyreotropin, glucose, and insulin were repeatedly measured over the entire 24-h session.Results In comparison with normal sleep, resting and postprandial energy expenditures assessed on the subsequent morning were significantly reduced after sleep deprivation by ≈5% and 20%, respectively (P < 0.05 and P < 0.0001). Nocturnal wakefulness increased morning plasma ghrelin concentrations (P < 0.02) and nocturnal and daytime circulating concentrations of thyreotropin, cortisol, and norepinephrine (P < 0.05) as well as morning postprandial plasma glucose concentrations (P < 0.05). Changes in food intakes were variable, and no differences between wake and sleep conditions were detected.Conclusion Our findings show that one night of sleep deprivation acutely reduces energy expenditure in healthy men, which suggests that sleep contributes to the acute regulation of daytime energy expenditure in humans.

  • Sleep restriction increases afternoon cortisol.

    “When appraised collectively, these studies show that sleep restriction increases afternoon cortisol: Table 2.”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [83]

  • Sleep restriction generally increases 24-hour energy intake relative to habitual sleep, with overeating ranging from about 180 to 559 kcal per day.

    “In general, studies reported increases in 24-hour energy intake when participants underwent sleep restriction relative to habitual sleep (Table 1), with the degree of overeating ranging from ≈180 to 559 kcal/d.”
  • In Benedict et al., decreased glucose tolerance during sleep debt resulted from reduced insulin sensitivity combined with beta-cell dysfunction, since insulin levels were not affected by sleep.

    “In the study by Benedict et al. [5], the decreased glucose tolerance in a state of sleep debt was the consequence of reduced SI combined to beta-cell dysfunction since insulin levels were not affected by the presence or absence of sleep.”

    From Sleep and metabolic function (2012) · cites this paper as [5]

  • Glucose tolerance was altered after 72-126 hours of total sleep deprivation and after 24 hours of total sleep deprivation.

    “Glucose tolerance was found to be altered in two studies, i.e., after 72–126 h of TSD [86] and after 24 h of TSD [5].”

    From Sleep and metabolic function (2012) · cites this paper as [5]

  • Of three studies assessing insulin sensitivity after a glucose load, two found reduced insulin sensitivity after sleep loss and one found reduced insulin sensitivity after recovery sleep.

    “Thus, of the three studies that assessed SI after a glucose load, two found reduced SI after sleep loss [5, 195] and one found reduced SI after recovery sleep [204].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
