Lack of sleep lead to weight gain

After numerous studies on sleep proved that the small number of hours of sleep caused an increase in the sense of hunger by increasing the hormone Ghrelin (stimulating the appetite) and leptin deficiency (inhibitor of appetite), which leads to an increase in eating and therefore weight gain. There are also studies suggest that lack of sleep makes the body resistant to the hormone insulin rises blood sugar even when healthy individuals, which increases the risk of diabetes. These studies concluded that a lack of sleep contribute to the rise in obesity is due to the problem of chronic sleep deprivation, and the wrong food behaviors such as over-the food, and eating junk food.
A recent study presented at the annual conference for "Association of Professional Societies of Sleep Medicine", which was held recently in the city of Boston to susceptibility of individuals under study to choose the food unhealthy, as a result Preference brain to ignore the use of health information related to food, and enthusiasm for species selection unhealthy food After exposure of people in one night to deny a sharp hours of sleep. The MRI examination revealed affected the frontal lobe of the brain changes as a result of lack of sleep, could limit the individual's ability to make sound decisions regarding complex function such as food selection of the fittest of the hull, and avoid improper food.
In another study related to the same subject matter, the researchers found the emergence of changes in the X-ray magnetic resonance functional, indicating activity sharp and unnatural at the center of "reward mentality" as a result of the individual food fat-rich calories sweets, and that after undergoing the deprivation of acute sleep, compared to actively individual normal and natural, after taking enough of the required hours of sleep. This indicates that a few hours of sleep, adversely affect the brain functions related to eating and make the body prone to weight gain over the long term.
If we take into account the widespread problem of obesity, which increased twice in the last twenty years, and we know that 8% of adults are owners little sleep, and that about 37% of individuals in civil societies suffering from chronic deprivation of proper sleep, we can understand the strong link between obesity and sleep disorders.
