Importance of sleep for weight management -
Ghrelin, for example, is a hormone that stimulates appetite. It increases with sleep deprivation, but its levels are lower in a fully rested state, so a person feels less hungry, Tasali said.
The brain also has reward centers that are activated when people are sleep-deprived, so they crave more carbohydrates or junk food. Bottom line: Losing weight all comes down to comprehensive lifestyle change, said NBC News Health and Nutrition Editor Madelyn Fernstrom, who called the new study carefully done.
Fernstrom said the new research provides compelling evidence that when chronic nightly sleep deprivation is restored to a healthy number of hours — around eight — food intake is reduced.
Adults who slumber more than nine hours a day may not be getting healthy sleep anymore or eating less, Tasali said. To get the recommended seven to nine hours of sleep a night, participants in the study received some of these tips:. Read an old-fashioned paper book around bed time: The participants were surprised just how useful it was to wind down and begin to fall asleep.
You should also limit activities that are stimulating or engaging, keeping you from slumber. Organize your morning routine a little better: Preparing your lunch bag the night before and other small changes can save you minutes in the morning, allowing more time for sleep.
People in the study were surprised how much of a difference all the tips made in their lives, Tasali said. Pawlowski is a TODAY health reporter focusing on health news and features. Previously, she was a writer, producer and editor at CNN.

Researchers observed an 11 percent increase in visceral fat accumulation inside the abdomen when subjects were sleep-deprived compared to getting a full nine hours meanwhile, the average weight gain during sleep deprivation was one pound more than under control conditions.
Functional medicine doctor Rich Joseph points out that sleep deprivation has acute and chronic effects. Some consequences, such as reduced insulin sensitivity, may be transitory, while the longer-term impacts on weight gain and metabolic disruption may result from chronic sleep loss.
Summary : Sleep deprivation consistently less than 7 hours nightly for the average adult decreases insulin sensitivity increases insulin resistance and hence, increases circulating insulin and blood glucose levels. Sleeping poorly can profoundly affect your diet, leading to higher calorie intake and overconsumption of carbs and sugar the next day.
A meta-analysis found that compared to normal sleepers, short sleepers were hungrier, ate on average more calories over the course of a day, and put on weight.
In one study, for instance, people who slept 4½ hours a night for four nights had higher levels of hunger-sparking ghrelin the following days and after each meal. As a result, they consumed roughly calories more—including more carbs and more sweet and salty snacks—than when they slept for 8.
Elevated evening ghrelin levels seemed to be linked to the short sleepers eating more sweets. In studies where sleep is restricted, and food is freely available, people tend to consume far more calories than they need to stay awake.
Having more hours to eat is one explanation, but research also points to the deactivation of brain networks involved in cognitive control and the activation of those involved in reward. In one study, sleep restriction reduced neural activity in three cortical brain regions that are needed to optimally evaluate food stimuli when people reported wanting food while also boosting neural activity in a subcortical region the amygdala that exaggerates the desirability of foods.
In the same study, sleep deprivation also caused cravings for high-calorie snacks and junk food that promote weight gain. This suggests, the researchers note, that sleep loss, as opposed to any metabolic need or hunger, produced these changes. Lack of sleep may also cause people to eat at a time of day that goes against their biology.
In one study, when people slept for only five hours a night and could eat whatever they wanted, they ate more carbs during the day and took in 42 percent more calories as after-dinner snacks, consuming more calories after dinner than during any other individual meal.
Nighttime snacking can be especially metabolically challenging. Staying up late can also push melatonin onset later, throwing off the hour circadian clock , which may lead to eating more food at nigh t.
Epidemiologic cohort studies have repeatedly found that people who are chronically sleep-deprived are at higher risk of obesity, likely for all the hormonal and metabolic shifts discussed here.
And the more limited the sleep duration, the greater the risk. Similarly, studies of hundreds of people that have examined the relationship between curtailed sleep and Type 2 diabetes have found that those who sleep hours a day have double the odds of prediabetes and Type 2 diabetes compared with those who get hours a day.
In some studies, short sleep was a more significant risk factor than lack of physical activity. As the research above indicates, weight loss is affected by a complex interplay of hormones, and a number of these are affected by sleep.
Here is more detail about other metabolic factors that contribute to fat storage, fat burning, hunger, appetite, and satiety—which all adjust depending on how well you sleep. Summary : Chronic sleep loss can also disrupt the balance of appetite and satiety signaling hormones and neurocognitive processes that influence your eating behaviors, which can result in cravings for ultra palatable foods, increased caloric consumption, and resultant weight gain.
Take these steps to improve your slumber to support a healthy weight. Aim for at least seven hours of sleep per night. Keep in mind that seven hours is the minimum recommended by sleep researchers ; you may need more than that for your best health. Set a regular bedtime and wake-up time—and resolve to stick with them.
Inconsistent sleep timing throughout the week can raise insulin resistance. Plus, trying to make up for lack of sleep during the workweek by sleeping in over the weekend can result in loading up on after-dinner snacks, gaining weight, and experiencing reduced insulin sensitivity.
And recent research suggests that post—weight loss, having a consistent bedtime may help you keep the pounds and fat off.
Accumulating research suggests that finishing calorie intake for the night between 6 p. and 8 p. is better for your metabolic health, according to Dorothy Sears, PhD, professor of nutrition at Arizona State University.
This gives your body time to store nutrients before circadian-controlled insulin action is impaired, in part, by the evening rise in melatonin.
Keep in mind that what you eat can also affect sleep. Caffeine , alcohol , and spicy foods are known sleep disruptors. Research suggests that insomnia triggers may also include large amounts of added sugar and processed grains.
Having more vegetables and fruit may act as an antidote. Go outdoors to get some sunshine as soon as possible after you awaken. In the evening, dim the lights up to two hours before bedtime, and turn off all electronics phones, tablets, computers to encourage parasympathetic activation and sleep onset.
Stop vigorous exercise an hour before bedtime. Exercise, even during the evening, can have a calming effect and help your mind relax and prepare for sleep. But a vigorous workout too close to turning in may not allow time for your heart rate to slow down, resulting in delayed sleep, poorer sleep quality, and nighttime awakenings.
Set up your bedroom for sleep. Mitigate thought- or anxiety-related insomnia. Use tools like journaling, meditation, breathwork , or reading to help calm your mind before bed. Struggling to sleep? Consider seeing a sleep specialist or coach. Sleep disorders like obstructive sleep apnea are pervasive and can magnify the adverse effects of sleep deprivation , resulting in a vicious cycle of weight gain.
A sleep specialist can determine whether you have a disorder and help you address it to improve your health and sleep.

Evidence shows that sleep may be the missing factor Ginseng for diabetes many people trying to lose weight. Getting fewer than 7 hours of sleep at night is considered short sleep 1. Short sleep — usually defined as fewer than 6—7 hours — has been repeatedly linked to a higher body mass index BMI and weight gain.
