Enough sleep to reduce weight, this is indeed true. Various studies have shown precisely how adequate sleep is necessary to maintain appetite and body weight.

Recent research published in the journal Proceedings of the National Academy of Sciences found that sleeping less than 5 hours a week will make us consume more calories. Most of the increase in calories caused by snacking after dinner. So in this study, when limited sleep hours, the volunteers actually eating / snacking during the biological clock just shows time to sleep.

The study, conducted by scientists at the University of Colorado's included 16 young men / young women. They were asked to spend the night in the bedroom that is set up the lighting, sound and also included tools to measure body functions during sleep. Popular rooms like this is also referred to as the sleep laboratory. Not to forget, for the sake of research, the number of calories of food consumed was also measured.

The first three days, they were asked to sleep for 9 hours. Furthermore, the participants were divided into two groups. The first group was 5 hours, while the second remained 9 hours for five days. The participants are provided a variety of food and snacks throughout the study. After five days, they exchanged bedtime. The first group finished 9 hours, and the second group so sleep 5 hours a day.
As a result, the group who slept only 5 hours, 5 percent burn more calories than those who slept 9 hours. But they also eat 6 percent more calories.

Those who sleep less less breakfast, but snacking so much more. Even the amount of calories from snacks eaten is greater than the number of calories of food routine.

Another study published in the Journal of Psychoneuroendocrinology also shows the effects of sleep deprivation on weight gain. This study provides the food served at the kitchen table of the 16 volunteers.

The first time they get enough sleep (8 hours) and the second time after sleep deprivation.
The result, while less sleep they tend to take turns eating more than enough time to sleep. The volunteers also reported feeling more hungry and upon inspection appeared to have increased levels of ghrelin. Ghrelin is a hormone that stimulates appetite.

After breakfast, sleep-deprived study participants also snacking more. Concluded, the lack of sleep would encourage a person to eat more.

Reminiscent of a recent research study a year ago,. In American Heart Association scientific meeting, presented a study that shows how the lack of sleep will increase our calorie intake.
The study found that a group of people who lack sleep have higher levels of ghrelin and leptin were lower. Again, ghrelin is a hormone that increases appetite, while leptin is responsible for suppressing appetite.

These studies pay attention to the effects of sleep deprivation with weight gain. But experts warn that we must look deeper. Not only on the amount of sleep less, but the sleepiness. How drowsiness effects on appetite for example. Because there are many diseases that cause people to continue sleeping sleepy despite sleep enough.

Snoring example. Snoring is considered to be caused by obesity, it may be otherwise, snoring causes obesity. Research in Turkey in 2005 show how snorers with sleep apnea stop breathing during sleep, have high levels of ghrelin and leptin were lower as people who sleep less.

Experts caution that weight gain and obesity has many interrelated factors. With the increasing number of scientific studies showing health relationships sleep and weight, it's time to not only think about exercise and diet. Enter health also sleep in your weight loss program
