Getting Only One Hour More of Sleep Each Night Might Improve Your Eating Habits

Adults who are sleep deprived want junk food, consume more calories, and have more harmful belly fat, according to studies.

Do you want to change your diet? Consider improving your sleep.

Researchers have recently shown that our sleep patterns have a significant impact on the quantity and types of food we eat as well as whether we acquire or lose body fat. Losing sleep can lead to hormonal and cognitive changes that increase food cravings and increase calorie intake, particularly from processed meals high in fat and sugar.

If you're one of the millions of individuals who suffer from chronic sleep deprivation, research indicates that even one hour more of sleep every night might improve your eating patterns and possibly even help you lose weight.

Many people struggle to get a decent night's sleep. According to sleep specialists, the typical adult needs at least seven hours of sleep per night. However, at least one in three individuals often misses out on adequate sleep. Some individuals don't get enough sleep so they may remain up late working or browsing the internet. Numerous individuals, including millions of people, experience sleep disorders such persistent insomnia, sleep apnea, or restless legs syndrome.

It's imperative to comprehend the variables that influence your everyday dietary choices if you want to improve your general health. Eating Lab will investigate the different biological and cultural factors that affect our eating patterns every Tuesday. Many studies now indicate that a significant factor is how well you sleep at night.

Why being tired makes you want to eat more

For instance, research demonstrates that persistently getting little sleep might lead to weight increase. According to studies, women who have a few nights of little sleep experience lower levels of the hormone GLP-1, which indicates fullness. Loss of sleep in males causes ghrelin, a hormone that promotes appetite, to increase.

In addition, those who lack sleep see alterations in their brain function. The pleasure-seeking and reward-related part of the brain responds more strongly to junk food, such as sweets, doughnuts, and pizza, when a person doesn't get enough sleep, according to studies, leading to stronger cravings for fatty meals. Additionally, a lack of sleep makes it more difficult for people to practice self-control because it lowers activity in other brain regions that govern how much food is consumed.

According to Marie-Pierre St-Onge, head of the Columbia University Irving Medical Center's Sleep Center of Excellence and associate professor of nutritional medicine. "The overwhelming evidence is that when you restrict sleep, individuals eat more," she added.

A team of academics examined data from 36 studies with several hundred thousand participants last year. According to their research, those who regularly slept for fewer than seven hours every night had a 26 percent higher chance of becoming obese than those who slept the suggested amount.

One qualification is that this study only found a link between insufficient sleep and weight growth. Scientists have conducted clinical experiments in which they recruited healthy persons and observed their eating behaviors while limiting their nightly sleep in order to better understand the association between sleep and nutrition.

In one study, subjects who got only 512 hours of sleep each night for two weeks consumed 300 more calories daily, largely from snacks like pretzels, cookies, chips, ice cream, and sweets. Many of these experiments were examined by St-Onge, who came to the conclusion that people typically consume between 300 and 550 more calories on days when they are sleep deprived than on days when they could sleep seven hours or more.

A "growth" of abdominal fat

The fact that lack of sleep appears to encourage a particularly dangerous type of body fat is perhaps most startling.

In a study that was earlier this year published in the Journal of the American College of Cardiology, researchers discovered that when healthy adults got just four hours of sleep per night over the course of two weeks, not only did they eat more and put on weight, but their abdominal fat also "expanded," especially the visceral fat that surrounds internal organs like the kidneys, liver, and intestines.

Your risk of getting heart disease, Type 2 diabetes, and a number of malignancies increases if you have large amounts of visceral fat.

How to enhance your nutrition while getting more rest

The good news for those of us who experience chronic sleep deprivation is that the negative effects of sleep loss on our diet and weight may be reversed. In one research, 80 overweight people who regularly slept an average of around six hours per night were included. The results were published earlier this year in JAMA Internal Medicine. One group received advice on how to sleep more soundly. The other group functioned as controls and received no additional information.

Training people to put down their cellphones and other electronic gadgets as they prepared for bed was an essential component of the therapy sessions. Esra Tasali, a researcher who also serves as the head of the University of Chicago's Sleep Research Center, explained that the study's main goal was to teach participants how to live without devices too close to bedtime.

The groups were then monitored by the researchers for two weeks. Even though they were not given any nutritional guidance, they discovered that those in the counseling group increased their sleep by about 1.2 hours per night and decreased their food consumption by 270 calories each day. They also reported feeling better and having more energy than the control group, as well as a little weight loss.

They acknowledged that it's acceptable to not reply to every text message an hour before going to bed, Tasali added.

Everyone should normally strive to obtain roughly seven hours of sleep each night, according to St-Onge at Columbia. If you wake up feeling refreshed and are not always worn out and exhausted, you have gotten enough sleep.

The secret is to turn off your electronics and go to bed at a decent hour. According to St-Onge, "some people may just require six hours of sleep, while others may require six and a half hours." However, I don't think anyone could function well on just five hours of sleep.
