Sleep more, lose weight, says study

Are you trying your best to eat right and exercise, but still not losing weight? One study suggests that lack of sleep could throw off a diet.

Research from the University of Chicago showed that dieters who slept for 8.5 hours lost 55 percent more body fat than dieters who slept 5.5 hours.

"Lack of sufficient sleep may compromise the efficacy of typical dietary interventions for weight loss and related metabolic risk reduction,” the study authors concluded in an article released Monday in the Annals of Internal Medicine, a journal of the American College of Physicians.

Not having enough sleep could affect a hormone called ghrelin, known to affect appetite and weight. An increase in this hormone level has been shown to make people hungrier and cause higher fat retention.

The dieters who slept less reported feeling hungrier throughout the course of the study.

The study had a small sample size – 10 sedentary nonsmokers, between the ages of 35 to 49 years with a body mass index considered overweight to obese (BMI 25-32), who stayed in what’s considered a closed study environment for two weeks.

They ate the same diet, consumed multivitamins and performed the same type of work or leisure activities. Six of them were assigned to 8.5 hours of sleep, and four slept 5.5 hours. Those who slept more lost more fat and maintained fat-free body mass.

"Together, these results suggest that the loss of sleep at times of limited food intake amplifies the pattern of ghrelin-associated changes in human hunger, glucose and fat utilization, and energy metabolism," the study authors wrote.

    Решение дополнительно на
    такой вопрос представляется весьма несложным:
    очевидно же, на том портале, тот
    который рекомендует это теперь сделать.
    Тем не менее все фактически попросту с одной стороны и также на порядок труднее, нежели показывается, с другой.

    Заблаговременно всего надобно избирать вебсайты совместно с хорошей подборкой
    секс роликов – это в целом выдаст способность всегда разбирать те видеороликов,
    какое-нибудь обзаводит и дополнительно какое тянет узнать.
    В такой мере что если на сайте в итоге до некоторой степени десятков видео, то вероятнее всего-лишь на долгое время всего этого ни в коем случае не предостаточно.

    Ещё безмерно нужно смотреть статистику апдейтов –
    все они могут являться довольно-таки частыми, в идеале – повседневными.
    Это такие обеспечивает юзеру приятный досуг
    и дополнительно говорит о этом, что администрация
    web-сайта точно о нем хлопочет, как будто
    заботится и конечно об личных пользователях.

    Дополнительно, подбирая, где смотреть порно online, требуется смотреть и
    дополнительно на так называемые стилевое разнообразие.
    Перечисленное все-таки отнюдь
    не собственная выборка, так как
    это там надобно быть представлено
    все, что едва можно себе лично вообразить – да, разумеется же, то, что представить немыслимо.
