Scientists have told how to sleep properly to achieve weight loss. It is more difficult for individuals suffering from lack of sleep to get rid of extra pounds even when following a diet.

Back in 2017, scientists from South Korea, based on the results of a study involving 17 thousand people, found that lack of normal sleep contributes to the development of obesity and a number of concomitant diseases. In addition, attempts to lose weight often did not bring the desired result. Similar conclusions were made by researchers at the University of Chicago. People who slept 5.5 hours a day lost extra pounds more slowly than those who rested for more than 8 hours, even with the same calorie-reduced diet. Experts from the University of Southern California in the United States doubt that the situation can be remedied by adding the right hours on weekends.
American and Belgian scientists believe that the weight gain associated with lack of sleep is due to the activity of hormones responsible for appetite. People with sleep deficiency have increased levels of ghrelin, which increases the desire to eat. In this case, the content of leptin, on the contrary, decreases, while it is responsible for the feeling of satiety. As a result, individuals who do not sleep for 8 hours tend to overeat more often and are less able to withstand the test of diet.

Even if sleep deprivation occurs within three days, leptin levels drop by 10%, as indicated by the findings of Japanese scientists. Because of this, the feeling of hunger wakes up more often, especially in the evening and closer to sleep. The body at this time consumes energy at the same level, which leads to the formation of excess weight, RIA Novosti writes.
The work of scientists from the United States indicates that some are prone to overeating due to the increased activity of the brain areas responsible for regulating appetite and functioning of the reward system. In volunteers sleeping 4 hours a day, activation of these areas was observed after eating sweet and fatty foods. In people suffering from sleep deprivation, there is a decrease in the sensitivity of body tissues to insulin. In the long term, a combination of factors threatens obesity and related ailments.
