A National Sleep Foundation survey showed that more than 40 per cent of the population self-reported that they slept longer during the weekend. It is unknown whether SR during a longer duration of CR affects body weight and fat.įurthermore, days of short sleep are often interspersed with longer sleep on other days in free-living individuals. For example, one study found that body weight was reduced after 1 week of SR but returned to baseline after an additional 2 weeks. Effects after a longer duration of SR may be different.

However, the results of these studies were limited to a short duration of intervention.

These studies suggest that sleep plays a role in the loss of weight and fat mass during CR. Additionally, an intervention involving a 4 day controlled diet combined with short sleep (4 hr in bed per day) induced less weight loss compared with habitual sleep (9 hr in bed per day). In a study involving 14 days of CR, participants lost less fat mass when they spent 5.5 hr in bed per day than when they spent 8.5 hr in bed per day. However, that study only determined baseline sleep using self-reported measures, which often differs from objective measures by at least 1 hr and did not have information regarding sleep during CR. Therefore, sleep restriction (SR) may affect neuroendocrine responses and energy expenditure during CR and reduce the effects of CR on body weight and fat.Ī previous study found a positive association between sleep duration and the loss of body fat in individuals who underwent an intervention involving 15–24 weeks of CR. Altered neuroendocrine factors, energy expenditure, and energy intake have also been reported with restricted sleep. Many observational studies support an association between insufficient sleep and greater body weight and body fat. Obesity is associated with serious health consequences and caloric restriction (CR) is a widely used strategy to treat obesity. Other metabolic changes were also observed. We found that sleep restriction resulted in less loss of fat but greater loss of lean mass among the total mass lost, despite similar weight loss between the two groups. Ad libitum sleep was allowed on the other 2 days each week so that the sleep pattern mimicked real life. Furthermore, the sleep restriction was moderate, approximated 60 min shorter on the 5 days of restricted sleep each week.

This study extends previous findings by examining the effects of a much longer duration of intervention (8 weeks) using a randomized controlled trial (caloric restriction alone or combined with sleep restriction). Previous studies suggest that sleep restriction during caloric restriction adversely affects weight-loss outcomes.
