Hormones and glucose samples of 24 h were collected, six days of four hours of sleep followed by six days of 12 h of sleep. Energy intake was evaluated | 11 males | 18—27 | No significant difference in energy intake between long and short sleep duration. A lower level of leptin | (Spiegel et al. 2004) |
Sleep laboratory 5.5 or 8.5 h/day sleep for 14 days, ghrelin levels, calories of consumed foods, serum leptin levels, and total energy expenditure (TEE) were measured | 11 individuals | 35 – 49 | No significant differences in the serum leptin levels, ghrelin levels, and TEE | (Nedeltcheva et al. 2009) |
24 h food recall was documented and compared to sleeping less than eight hours or more | 240 adolescents | 16—19 | Those who had more energy, fat, and snacks intake had less than eight hours of sleep | (Weiss et al. 2010) |
Sleep was evaluated for two weeks by sleep log and actigraphy. The first week was four hours of sleep, the second week was nine hours of sleep, and the fifth-day food intake was documented | 15 females, 15 males | 30 – 49 | Participants consumed more calories during the short sleep duration | (St-Onge, et al. 2011) |
The participants self-reported eating behavior, sleep duration, and alcohol consumption | 703 individuals | 18—64 | Higher calorie intakes from alcohol were recorded during sleep of fewer than six hours | (Chaput et al. 2012) |
Obesity therapy was used for six months, the 24-h recall conducted the nutrition assessment, and sleep was evaluated at baseline and post-therapy | 41 obese children | 20—50 | More extended sleep time results in less calorie intake. Each one-hour sleep increase resulted in 186 cal less calorie intake | (Clifford, et al. 2012) |
Five-day, five-hours, and 9-h sleep duration were used. The calorimeter method calculated energy expenditure according to carbon dioxide production and oxygen consumption | 16 individuals | Mean age 22.4 | Insufficient sleep increased TEE by 5%. It was reported that insufficient sleep impacts hunger by changing the peptide YY, ghrelin, and leptin hormone levels | (Markwald, et al. 2013) |
