Think Supper Makes You Fat? This Might Be Worse
The early bird catches the worm? Maybe there are no worms to catch because the insomniac bird ate them all.

Study shows that lack of sleep makes us want to eat
A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, the U.S. study suggests.
dailymail.co.ukResearchers have long pointed to a correlation between a steep rise in obesity in industrialised nations and a decline in sleep duration. A causal link was suspected, but science has not been able to explain the mechanism, until now.

Scientists scanned the brain activity of 23 sleep deprived young adults
Scientists said Tuesday they had found evidence that a lack of sleep causes changes in brain activity that lead to people feeling hungrier and craving more fattening foods.

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.
Researchers 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.
They found that when you experience sleep loss, your need for desire and reward increases
They found impaired activity in the sleep deprived brain's frontal lobe, which governs complex decision making, but increased activity in deeper brain centres that respond to rewards.

Take out all the scientific mumbo-jumbo and it simply means:
In conclusion, the less you sleep, the more you want to eat, the higher your chances of getting obesity.<br/><br/>

"An additionally interesting finding was that high calorie foods became more desirable to the sleep deprived participants," said study co-author Matthew Walker of the psychology department at the University of California in Berkeley.

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

‘These results shed light on how the brain becomes impaired by sleep deprivation, leading to the selection of more unhealthy foods and, ultimately, higher rates of obesity,’ said Stephanie Greer, a doctoral student in Professor Walker's Sleep and Neuroimaging Laboratory.
