MessageToEagle.com - Using functional magnetic resonance imaging (fMRI), UC Berkeley researchers scanned the brains of 23 healthy young adults, first after a normal night's sleep and next, after a sleepless night.

They measured brain activity as participants viewed a series of 80 food images that ranged from high-to low-calorie and healthy and unhealthy, and rated their desire for each of the items.

As an incentive, the participants of the study were given the food they most craved after the MRI scan.



The researchers found impaired activity in the sleep-deprived brain's frontal lobe, which governs complex decision-making, but increased activity in deeper brain centers that respond to rewards.

Additionally, the participants favored unhealthy snack and junk foods when they were sleep deprived.

"What we have discovered is that high-level brain regions required for complex judgments and decisions become blunted by a lack of sleep, while more primal brain structures that control motivation and desire are amplified," said Matthew Walker, a UC Berkeley professor of psychology and neuroscience and senior author of the study.

"High-calorie foods also became significantly more desirable when participants were sleep-deprived.," Walker added.

"This combination of altered brain activity and decision-making may help explain why people who sleep less also tend to be overweight or obese."



Previous studies have linked poor sleep to greater appetites, particularly for sweet and salty foods, but the latest findings provide a specific brain mechanism explaining why food choices change for the worse following a sleepless night, Walker said.

According to the team, the study indicate that "getting enough sleep is one factor that can help promote weight control by priming the brain mechanisms governing appropriate food choices."

The research is published in the journal Nature Communications.
