Can you lose weight by "lying flat"?

As we all know, before the new crown pandemic, the obesity pandemic has already "swept the world", and more than 2 billion people have been clinically diagnosed as obese or overweight
.

The main cause of obesity is energy imbalance caused by chronic caloric intake exceeding energy expenditure
.

Lack of sleep caused by staying up late, jet lag, insomnia, etc.
, will make people fat
.

Because lack of sleep will cause the body to secrete an appetite-stimulating hormone, which will make you addicted to food: I want to eat supper, I want to eat high-calorie food.
.
.
Over time, the body's energy intake is too much, inevitably become a fat man
.

If the above point is true, can it be understood that increasing sleep time can prevent obesity? Now, a real-world trial brings new evidence
.

On February 8, Beijing time, in a randomized clinical trial published in JAMA Internal Medicine, a journal of the American Medical Association (JAMA), researchers from the University of Chicago and the University of Wisconsin-Madison found that habitual nightly Overweight young adults who slept less than 6.
5 hours lost an average of 270 kcal per day and lost nearly a pound over the two-week intervention period after gaining an average of 1.
2 hours of sleep per night
.

Losing less than 1 pound in two weeks does not seem to be attractive
.

But the new study not only investigated the effects of prolonged sleep on caloric intake, but more importantly, it was conducted in a real-world setting: All participants slept in their own beds and were tracked with only wearable devices on.

.

Other than that, there is no difference from everyday life
.

Fat people how to eat and how to eat
.

The clinical study involved 80 adults between the ages of 21 and 40
.

All participants had a body mass index (BMI) between 25 and 29.
9, classified as obese/overweight
.

Their habitual sleep duration was 6.
5 hours or less per night
.

The researchers observed the participants for two weeks to establish a baseline data, then randomly divided them into two groups
.

The control group continued to maintain their sleep habits without any intervention, while the other group received a "personalized sleep wellness counseling session" aimed at extending their sleep time to around 8.
5 hours
.

To objectively track participants' caloric intake, the researchers utilized a "double-labeled water" method and changes in energy storage
.

After a "counseling session," participants in the intervention group gained an average of 1.
2 hours of sleep per night
.

Despite the absence of other prescriptions for life>
.

The researchers found that for every additional hour of sleep, energy intake decreased by 162 kcal
.

Overall, the intervention group that increased sleep by 1.
2 hours per night reduced caloric intake by an average of 270 kcal per day and lost 0.
48 kg of body weight over the two-week intervention period, compared with the control group, compared with the control group.
The average weight gain was 0.
39 kg (a difference of 0.
87 kg between the two groups)
.

If this effect is maintained long-term, this will translate into a weight loss of approximately 12kg over three years
.

Although the study did not systematically assess factors that might influence sleep behavior, limiting electronic device use before bed appears to be a key intervention, the researchers said
.

"This is not a weight loss study," said the study's corresponding author and director of the UChicago Sleep Center at the University of Chicago School of Medicine
.
"
But even in just two weeks, we have quantitative evidence of reduced caloric intake and the onset of a negative energy balance, known as ingestion.
Eat fewer calories than you burn
.

If healthy sleep habits are continued for longer, this can lead to clinically significant weight loss
.

Many people are trying to find ways to reduce their caloric intake, but just get more sleep and you'll be Calorie intake can be drastically reduced
.

" The researchers say potential mechanisms that might explain these results will be explored in the future
.

They believe the work will drive new, larger studies of weight control to determine whether longer sleep duration helps with weight loss
.

Previously, in a systematic review meta-study published in the European Journal of Clinical Nutrition, a research team from King's College London, UK showed that sleep-deprived people may consume more calories the next day, resulting in an average daily Intake an extra 385 kcal
.

That's the equivalent of one and a half pancakes
.

The study agrees with this latest study, suggesting that sleep, in addition to diet and exercise, is a potentially important factor in effective weight gain control
