Losing just one hour of sleep a night means that tomorrow you will eat 200 calories more than
- an average of 200 calories more, and it is the same that the two scoops of ice cream;
- more than 6 grams of fat and 32 grams of carbohydrates a day;
- This is equivalent to a teaspoon of butter and 100 g of spaghetti;
- lack of sleep can make us constantly munching couch potatoes;
- may be because sleep disorders lead to hormonal imbalance.
The researchers analyzed the "sleepy" habits of 342 young people. On average, they slept about seven hours each night. However, when the adolescents slept more than an hour or an hour less, they ate an average of 201 extra calories a day. This is the equivalent of cake or two balls of chocolate ice cream. The next day, they consumed about 6 grams more fat - the same as a teaspoon of butter or truffle milk chocolate and 32 grams more carbohydrates, which is equivalent to 100 grams of pasta.
Sleep disorders in adolescents by 60% increases the likelihood of night snacking on weekdays and 100% on weekends. Study leader Feng Hui said:
«Our study is the first to objectively measurable sleep and physical activity of teenagers for a week in accordance with their eating habits in real life, not in a laboratory».

To determine how long they slept each night, teenagers more than seven days wore bracelets, measured the cycles of activity and rest. It takes into account the frequency of meals, to determine how many calories, proteins, fats and carbohydrates are consumed regularly.
The researchers then analyzed the relationship between sleep duration, daily changes in sleep duration and diet. The results were adjusted for age, gender, race, and body mass index. The study found that teens slept on the weekend more than on weekdays.
Scientists say that one possible explanation for the effect of changes in sleep is that lack of sleep can make a teenager less active the next day, and he would sit in front of the TV, always something chewing. Another explanation - changes in the structure of sleep lead to a hormonal imbalance that causes the teenager to eat more.
Scientists have long known the hormone leptin, which regulates appetite. As one of the two "hunger hormone" in the body, leptin reduces appetite (his partner ghrelin increases appetite). When a person is hungry, his fat cells secrete leptin, which effectively blunts appetite, telling the brain that it's time to stop eating. But lack of sleep dramatically lowers leptin levels, giving a signal to the brain to eat more food. Simultaneously, increased levels of ghrelin increases hunger.
Scientists believe that much more important to have a regular sleep the same duration than one night to sleep more, and in others - less.
Responsibility for overeating is on hormones?
In 2012, Robert Lustig, professor of clinical pediatrics at the University of California, explained the new scientific theory about why people eat too much. He argues that the desire to overeat and recreation is not a sign of weakness, and considers this hormonal problem caused by excessive consumption of sugar. He blames the hormone leptin, which regulates appetite. When we ate, our cells produce leptin, which suppresses appetite. But Professor Lustig warns that sweet tooth can disrupt this process.
