Sleep more to slim down, scientists say
by Brigitte Castelnau Fri Apr 4, 3:00 PM ET
PARIS (AFP) - An extra hour between the sheets at night might be the key to shedding excess weight and fighting obesity, according to recent research.
"More sleep could be the ideal way of stabilising weight or slimming," said neuro-scientist Karine Spiegel, of France's INSERM, a public organisation dedicated to biological, medical and public health research.
While poor eating habits and lack of exercise clearly play a role in the global rise of obesity, recent data indicates that lack of sleep may also be a factor, and one that is often under-estimated.
Around 30 surveys carried out on wide population samples in seven countries have underlined a link between lack of sleep and excess weight or obesity in both children and adults, Spiegel said.
The first of the studies, carried out in 1992 in France, highlighted the problem in children and teenagers. Spiegel said the increase in obesity in the US in the second half of the 20th century corresponded with a mounting decrease in sleep.
Two key hormones produced at night which help regulate appetite were at play, she said.
Grehlin makes people hungry, slows metabolism and decreases the body's ability to burn body fat, and leptin, a protein hormone produced by fatty tissue, regulates fat storage.
"We have shown that less sleep (two four-hour nights) caused an 18 percent loss of appetite-cutting leptin and a 28 percent increase of appetite-causing grehlin," she said.
Such hormonal changes made people hungry for foods heavy in fats and sugars such as chips, biscuits, cakes and peanuts, she added.
The sleep loss caused a 23 to 24 percent increase in hunger, Spiegel said, translating into an extra 350 to 500 kilocalories a day, "which for a young sedentary adult of normal weight could lead to a major amount of added weight."
It was unclear whether several years of sleep deprivation could lastingly harm the body's ability to restore a balance between the two hormones.
A study released in Washington in February showed children lacking shut-eye faced a greater risk of becoming obese than kids who got a good night's sleep.
Each extra hour of sleep cuts a child's risk of becoming overweight or obese by nine percent, according to an analysis of epidemiological studies by researchers from Johns Hopkins Bloomberg School of Public Health.
By contrast, children who got the least sleep had a 92 percent higher chance of being overweight or obese than children who slept enough, said the study published in the journal Obesity.
"Our analysis of the data shows a clear association between sleep duration and the risk for overweight or obesity in children. The risk declined with more sleep," said Youfa Wang, a senior author of the study.
"Desirable sleep behavior may be an important low cost means for preventing childhood obesity and should be considered in future intervention studies," Wang said in a news release.
The researchers reviewed 17 published studies on sleep duration and childhood obesity.
Some research recommends that children under five years old sleep 11 hours or more a day, while children age five to 10 should get 10 or more hours of sleep, and children older than 10 should sleep at least nine hours.

Yes, it's hard to eat when you're sleeping! Okay, I am off to bed!

Well, you know I have to agree if the study was done in Paris! Of course, they eat small portions, walk everywhere and most don't have elevators in their apartments. Walking up four flights of stairs everyday will burn calories! But, I do think we don't get enough sleep. I always felt that I only needed 5 or 6 hours sleep, but I think it hurted my body in the long run. Now,sleep is my friend! Is there a snoozing icon? :rofl;

Hmmmm, sleep more, eat less = possible weight loss = Thanks Einstein for that possible conclusion. Glad you pointed that out or I would have never thought of that. I gotta get on one of these boards who get paid to come up with some of these studies :rofl; :rofl;

Sleep is my friend!

Before they got the anemia under control, I was sleeping 14 hours a day - so how come I'm not stick thin? ;D

My Mom bought me a t-shirt with Eeyore on it. It says "I need a nap." That is my mantra!
-
What? What is this about? I was sleeping.
-
I sleep more hours a day than I'm awake and I eat only 1 or 2 meals a day. If this was true, I should weigh 90 pounds soaking wet. but I don't. ???

If sleep made you thin why am I so fat?

If an extra hour a night helps shed excess skin, then please put knock me out for a month. I should be at goal weight by then! ;D

Hey, now you're talking! They do it with drug addicts who are going through withdrawal, they just knock them out to avoid the bad side effects (although, it's remembering that struggle that might keep them sober in the future... but anyway). So if you were in a deep sleep for a few weeks... just think ... weight loss and beauty sleep too!

And bedsores! ;D

On a Saturday Night Live episode, Chris Farley did a spoof commercial with something like Nyquil. I think it was to miss the flu season and he wakes up months later with a Grizzly Adams beard.
