Not getting enough sleep could kick start a craving for junk food. A new study presented at the "Sleep 2012" conference, looked at the brain scans of twenty-five adults.
Some were restricted to four hours of sleep a night for five nights and the others were allowed to sleep up to nine hours. Researchers found the reward center of the brain was activated when people who were sleep deprived saw pictures of unhealthy food. However, it was not activated when they saw healthy food. They also found the sleep deprived adults ate more fatty foods during the trial.
