Providing 7-8 hours of sleep every night protects against increased appetite and unnecessary eating.
Research shows that lack of sleep increases food consumption. The researchers tracked the sleep quality of 17 men and women between the ages of 18 and 40.
It has been found that providing only 2/3 of the required sleep is associated with an additional average of 549 calories per day.
Thus, a week of sleep deprivation can lead to an increase in body weight by half a kilogram, explains researcher Dr. Andrew Calvin of the Mayo Clinic , Rochester.
People with normal sleep consume about 143 calories less than usual, the researchers found.
Many believe that if they are awake for a long time, they will move more and burn more calories, but according to the results of the study, this is not true, the expert said. There was no significant difference in the levels of physical activity in the participants in the two groups.
According to the study, sleep deprivation is also associated with a slight increase in levels of the hormone leptin, which regulates the body's energy balance, and a decrease in those of ghrelin, the hormone that controls appetite.

Other studies also show that lack of sleep is associated with weight gain and the risk of obesity in both adults and children.
Drowsiness, fatigue and stress during the day, due to lack of sleep, can make it easier to succumb to the temptation to eat more treats.
When we are sleep deprived and sleepy, the brain is less active than when we are rested. Lack of sleep makes us tend to succumb to momentary sensations and desires without assessing the risk, in this case of excess weight.
