Lose weight while sleeping may sound like a dream come true, because losing weight without the need to fight hard. But research has shown that healthy sleep can affect appetite which ultimately have an impact on weight.
The results have been published in the Annals of Internal Medicine and Journal of Clinical Endocrinology and Metabolism shows that sleep duration may affect appetite, the result can also be an effect on body mass index (BMI).
When people get a good nights sleep, at least 8 hours, your body produces the hormone leptin that regulates appetite. With enough leptin, people will feel full and satisfied after a meal so it does not need to eat a lot to make the stomach feel full, as reported by the LIVESTRONG, Tuesday (12/04/2011).
Adequate rest is also regulate the hormone ghrelin, a hormone that increases appetite. Reverse the positive effects of sleep deprivation, by making the production of leptin and ghrelin is reduced more, so that people feel less satisfied after a meal and consequently eat more and more frequently, which affects the weight gain.
Sleep deprivation can make people want to continue to eat more servings. This is caused by the body’s internal clock that is not normal, so many people who sleep less gain weight suddenly.
In addition, lack of sleep also can make people not energized, so have a greater desire to eat foods that are sweet and starchy, or worse by drinking high fructose corn syrup.
These foods can provide an instant energy but causing blood glucose levels rise and fall dramatically, which ultimately makes you hungry faster and eat a lot.
National Sleep Foundation reports that less than 7 hours of sleep each night was associated with an increased risk of obesity, diabetes and an additional health problem in many clinical studies.
However, sleeping more than 9 hours of sleep per night is also not good because it can increase the risk of stroke.
Therefore, sleep healthy with sufficient time, ie 7-9 hours for adults. Not only the resting muscles, sleep also provide an opportunity for the immune system to produce hormones immunity.
