How sleep deprivation affects our choice of food

German scientists at the University of Klinn have found that lack of sleep is linked to an increase in access to so-called fast food.

Fenomen can be explained by the impact of sleep deficits on the brain's reward mechanisms, researchers say.

In addition, sleep deprivation can disturb the balance of hormones that regulate appetite and sense of satisfaction.

A number of early studies have linked a brief sleep to an increase in the risk of overweight, writes Neuroscience magazine.

The new findings are collected from 32 healthy men aged 19 to 33.
