Sleep loss can modify energy intake and expenditure. To determine whether sleep restriction attenuates the effect of reduced-calorie diet on excess adiposity. Randomized two-period two-condition crossover study. University clinical research center and sleep laboratory. 10 overweight nonsmoking adults (3F/7M); mean (SD) age 41 (5) y; body mass index 27.4 (2.0) kg/m2. 14 days of moderate caloric restriction with 8.5 or 5.5-hour nighttime sleep opportunity. Primary: loss of fat and fat-free body mass. Secondary: changes in substrate utilization, energy expenditure, hunger, and 24-h metabolic hormone concentrations. Sleep curtailment decreased the fraction of weight lost as fat by 55% (1.4 vs. 0.6 kg with 8.5 vs. 5.5-h sleep opportunity, 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 towards oxidation of less fat. The nature of the study limited its duration and sample size. 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.
