Abstract

BACKGROUND: Sleep loss can modify energy intake and expenditure. OBJECTIVE: To determine whether sleep restriction attenuates the effect of a reduced-calorie diet on excess adiposity. DESIGN: Randomized, 2-period, 2-condition crossover study. SETTING: University clinical research center and sleep laboratory. PATIENTS: 10 overweight nonsmoking adults (3 women and 7 men) with a mean age of 41 years (SD, 5) and a mean body mass index of 27.4 kg/m² (SD, 2.0). INTERVENTION: 14 days of moderate caloric restriction with 8.5 or 5.5 hours of nighttime sleep opportunity. MEASUREMENTS: The primary measure was loss of fat and fat-free body mass. Secondary measures were changes in substrate utilization, energy expenditure, hunger, and 24-hour metabolic hormone concentrations. RESULTS: Sleep curtailment decreased the proportion of weight lost as fat by 55% (1.4 vs. 0.6 kg with 8.5 vs. 5.5 hours of sleep opportunity, respectively; P = 0.043) and increased the loss of fat-free body mass by 60% (1.5 vs. 2.4 kg; P = 0.002). This was accompanied by markers of enhanced neuroendocrine adaptation to caloric restriction, increased hunger, and a shift in relative substrate utilization toward oxidation of less fat. LIMITATION: The nature of the study limited its duration and sample size. CONCLUSION: The amount of human sleep contributes to the maintenance of fat-free body mass at times of decreased energy intake. Lack of sufficient sleep may compromise the efficacy of typical dietary interventions for weight loss and related metabolic risk reduction. PRIMARY FUNDING SOURCE: National Institutes of Health.

  • More recent investigations found leptin unaffected or elevated.

    “leptin was unaffected [30], [32], [66] or elevated [20], [29], [31].”
  • In a controlled-feeding weight loss study, participants lost an equivalent amount of weight in both sleep conditions, but in the sleep restriction condition they lost more fat-free mass and less fat mass than with an 8-hour sleep opportunity.

    “Because of the controlled-feeding nature of the study, participants lost an equivalent amount of weight in both sleep conditions. However, in the sleep restriction condition, participants lost more fat-free mass and less fat mass than when the same weight loss treatment was performed with an 8-hour sleep opportunity.”
  • Lack of sleep may attenuate the efficacy of dietary interventions for fat loss.

    “These results indicate that lack of sleep may attenuate the efficacy of dietary interventions for fat loss [117].”

  • In overweight and obese middle-aged adults on moderate caloric restriction, 14 nights of 5.5 h versus 8.5 h sleep opportunity decreased the proportion of weight lost as fat by 55% and increased fat-free mass loss by 60%.

    “At the end of the 2 weeks of sleep curtailment, the proportion of weight lost as fat was decreased by 55%, and the loss of fat-free body mass was increased by 60%.”

    From Sleep and metabolic function (2012) · cites this paper as [117]

  • In the caloric-restriction study, leptin declined with weight and adiposity loss without a significant independent effect of sleep loss, so negative energy balance most likely overrode the effect of sleep duration.

    “For example, in the study that submitted the subjects to caloric restriction, leptin levels declined in parallel with the loss of weight and adiposity without a significant independent effect of sleep loss: The negative energy balance most likely overrode the impact of sleep duration [117].”

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.
