Sleeping arrangements are as important as diet and exercise to get your weight balanced. The study by a team from the University of Chicago shows, lack of sleep can reduce the effects of the diet. When people who are dieting have quality sleep, reduced body weight two times more than the dieters who sleep less. The reaction was suffering from sleep deprivation to obesity is also carried out by scientists from Australia about the link between sleep deprivation and weight gain.

Meanwhile, experts from Columbia University, New York, who studied the sleep habits of 18,000 people found that people who sleep less than four hours each night and 73 percent risk of overweight later in life than people who sleep 7-9 hours every night. Even those who averaged six hours of sleep each night had a 23 percent risk of obesity. On the other hand, people who are too much sleep, about 10 hours each night, has a 11 percent risk of suffering from obesity.

The experts believe, lack of sleep can disrupt hormones ghrelin and leptin. Both are hormones that regulate hunger and appetite. When we lack of sleep, your body will react like when we eat less; leptin levels will fall and ghrelin levels soared. As a result, the stomach will feel hungry and stimulate appetite to eat a diet rich in fat and sugar. Of course this will make the weight soared. These hormonal changes also disrupt the metabolism so more fat is stored.

Other studies have shown, lack of sleep will interfere with the body’s biological clock or circadian rhythms that regulate glucose and insulin. Lack of sleep increases the hormone cortisol, a hormone that also regulates the use of energy in the body. High levels of cortisol are associated with insulin resistance and high body mass index.
