People could be putting their weight loss regime under serious threat if they fail to get a good night's sleep.
Researchers at the Mayo Clinic in Rochester, Minnesota, have found that sleep deprivation may be leading individuals down the path towards obesity.
In order to reach such a conclusion, the group surveyed 17 normal young men and women for eight nights, each of which were seen to live a healthy life.
Half of the participants slept normally throughout the duration of the research, while the other half only snoozed for two-thirds the recommended time.
During their waking hours, the sleep deprived group were found to consume around 549 additional calories per day more than those who had a restful night.
Andrew D. Calvin, co-investigator, cardiology fellow and assistant professor of medicine at the Mayo Clinic, commented: "Sleep deprivation is a growing problem, with 28 per cent of adults now reporting that they get six or fewer hours of sleep per night."
