Sleep-deprived people eat 300 more calories a day

When people are sleep-deprived, they eat almost 300 calories a day more than when they are well-rested. And ice cream is one of their favorite foods to eat when they're tired, a new study shows.

Scientists have known for years that too little shut-eye can lead to weight gain and obesity.
So researchers at Columbia University decided to find out whether people actually consume more when they are sleep-deprived vs. well-rested.
They recruited 26 normal-weight men and women who routinely slept between seven and nine hours a night. The participants came into an inpatient hospital-like setting for six days on two different occasions. Half slept four hours a night for six nights. The other half slept for nine hours a night for six nights.
For the first days, they received a portion-controlled diet, but the last two days they could eat as much as they wanted from food they chose themselves. The entire procedure was repeated a second time with people getting a different amount of sleep.
Findings, reported Wednesday at an American Heart Association meeting in Atlanta:
•Participants consumed an average of 296 calories more when they were sleep-deprived compared with when they were well-rested.
•When women were sleep-deprived they ate an average 329 more calories a day vs. when they were well-rested; men ate 263 more calories.
•Overall, most of the extra calories came from high-fat foods such as ice cream and fast foods.
•When women were sleep-deprived, they ate an average of about 31 more fat grams a day. Men's fat intake didn't climb that much.
"Ice cream stood out as the preferred food during the sleep-deprived state," says lead author Marie-Pierre St-Onge, an assistant professor of clinical nutrition medicine at Columbia. "Sleep deprivation makes you more susceptible to overeating, so that can be something to consider when you're trying to lose weight."
This confirms other research that short sleep duration is associated with eating more and could lead to obesity and an increased risk of cardiovascular disease, St-Onge says.

She says one other study also found that sleep-deprived adults ate almost 300 calories more a day than those who were well-rested.
St-Onge is still analyzing the data on how the sleep deprivation may affect appetite hormones.
However, other studies show that sleep-deprived people have higher levels of ghrelin, a hormone that stimulates hunger, and lower levels of leptin, a fullness hormone, than people who are well-rested.
University of Chicago sleep researcher Eve Van Cauter, a leading expert in this field, says that an additional 300 calories day "is a substantial increase in energy intake that, if maintained chronically, would lead to rapid and robust weight gain."
The reduction in sleep in this study "is pretty drastic but nonetheless occurs in real life under a number of situations, including among medical interns and residents who are known to pack on the pounds," she says.
Gina Lundberg, a spokeswoman for the American Heart Association and a preventive cardiologist in private practice in Atlanta, says she thinks it's possible that sleep deprivation provides a "double whammy" for weight gain — that is, people not only eat more when they're tired but also may be less likely to exercise. "When you're tired, you're less motivated to exercise. You just want to go home and go to bed," she says.
Both the higher calorie and fat intake and possibly being less active could be detrimental to your heart over the long term, she adds.

That's how I gained the bulk of my weight. Both my kids as babies were good at staying awake at night and I ate in an effort to stay awake. So glad that stage of my life is over!0
-
I'd believe it.0
-
It makes sense - When I have my 5 am shifts I definitely eat more, because I'm awake longer!0
-
Makes sense.0
-
Some studies say it could be even more than 300. Definitely true for me though. If I'm tired (like today) I just want to graze0
-
I could definitely see that. I'm pretty much sleep deprived all of the time with my 7 month old who thinks it's party time from 12:30 AM until about 4:00 AM. It can be a real struggle being this tired and eating at a deficit. When I'm up with him in the middle of the night, I want Jelly Beans like a crazy person.0
-
I do wonder whether the sleep-deprived in that study ate more simply because they were awake more hours of the day and had more time to eat rather than it being a physiological response.
But in any case it still makes sense that lack of sleep could lead to weight gain.0 -

mmmmm jelly beans.... mmmmm
do you know there is a swedish fish jelly bean? It's new.. I'm been watching the stores for them.. my mouth is watering.. swedish fish are fat free...
mmmmmm jelly beans..0 -
Absolutely. I slept badly last week for one reason or another and even though I wasn't eating more late at night, the next day I'd be absolutely ravenous and eating much more to try and perk myself up a little bit. Raging appetite.0
-
Maybe for some people that's how it works. For me, I'm lucky to get 4-6 hours of sleep a night. I haven't found myself needing more calories. I suppose though, I've gotten use to my little sleep over the years and have adjusted.0
-
TL; DR
However, the title is right on. The less I sleep, the more I eat. Midterms are killer.0 -
True for me, although I think it's at least partly because I like to snack so if I'm awake more hours then I want more snacks.0
-
TL;DR - However, I agree. I have read several articles which supports the title.0

Lack of sleep (7-8 hours nightly) actually does mess with your hormones, which include those that cause increased hunger. The body perceives lack of sleep as a stressor.0 -
No wonder moms have such a hard time losing the baby weight!! Stinky little buggers
I know I'm always hungrier when I don't get enough sleep (which happens alot) especially in the afternoon or evening when my energy levels tend to crash the hardest...0 -
I believe it.. being chronically exhausted.. you eat for a pick me up when all you want to do is go lay down. I seem to have adjusted to not needing more than 4-5 hours of sleep (sometimes not even all in a row)... but even now, I save the bulk of my calories for times in the day I know I usually lag and eat less the times my natural energy level is at it's highest.0
