"In young adults sleep deprivation has been found to cause fat accumulation in the belly for the first time.
Naima Covassin from the Mayo Clinic Rochester Minnesota studied 12 healthy slim young people aged between 19 and 39. The poor souls were randomised to two weeks of just 4 hours sleep a night or 9 hours sleep followed by a three day recovery period. During this time the subjects were kept in hospital and factors such as calorie intake and energy output were measured.
Over the two weeks of sleep deprivation, the subjects put on an average of a pound or half a kilogram and all of it on the belly.
This was because they consumed an extra 308 calories a day compared to the 9 hours a night group.
Despite stopping the study after two weeks and then during recovery sleeping more, eating fewer calories and their total weight coming down, their bellies continued to get bigger, by an average of 3 cm by day 21 of the study.
This could be why shift workers are so prone to gaining fat around the belly.
The continued rise in belly fat could have been missed if body weight, BMI and overall body fat percentage were the only factors measured.
Dr Harold Bays who is an endocrinologist and president of the Louisville Metabolic and Atherosclerosis Research Centre says “Sleep disruption results in fat dysfunction and this may result in increased cardiovascular risk factors and unhealthy body composition including an increase in visceral fat.”"

Things Your Mind and Body Are Doing While You SleepYou are probably well aware that your body requires adequate sleep every night – ideally around seven to eight hours – to function properly and maintain your health, but you may not realize how much goes on while you are sleeping.
One of which is throughout the night, you lose weight due to expelling humid air and losing water through perspiration. As opposed to during the day, there is no consumption of food or beverages to offset this effect. This leads to a decrease in pounds by the morning. During sleep, your body also regulates hunger hormones. This means that you are better equipped to fight off junk food cravings if you got an appropriate amount of sleep the night before.

If only I could sleep longer than 5-6 hrs...need to work on this!
...sleep is a necessary part of life.
Adequate sleep (7 hours) is definitely a Must in maintaining mental and physical health.
At least I have an excuse now :)
So true
Thank you for sharing these two articles. They are very interesting. I try for 8 hours of sleep (otherwise I tend to get a bit cranky).
Un estudio muy interesante. Besos.
That makes sense. The longer we are awake, the more we eat. Also, little rest has rarely being known to be good for the body in any way.
Interesting
I've never had more than five hours sleep in my life. Now I know why I have a tummy, even though I'm tiny.
I believe this because it happened to my hubby working shift work, he was getting an average of 5-6 hours sleep
I sleep much worse these days than I used to.
i get pretty good sleep, most of the time. but i have a fatter belly...what's up with that?? hehe
I enjoy visiting your blog because I learn things that I otherwise probably wouldn't hear about.
This is very interesting, thanks for sharing! Valerie
Fascinating article! Thank Jan :)
Sigh. I have huge sleep issues and now you have given me one more thing to worry about.
Hi Jan,
Excellent post.
I knew the importance of sleep, but not that we lost weight during sleep. We are always learning.
Greetings and all the best.
Goodness, how very interesting.xxx
I'm so fortunate to never have had a problem with getting a good night's sleep. It's so important, after all.
Interesting!
Lack of sleep causes a lot of issues!
I am doing a lot better and in less pain. Just a long road ahead for it to reverse hopefully! Thanks for asking :-D
Very interesting. I have always slept very well and the older I get, (70) I sleep deeper and even better.
This is very interesting, and it is also helpful. I had no idea about this until I read about it here. Thank you for sharing this.
Wishing you well, my friend. Have a wonderful Wednesday night!
This is so interesting...now wonder I have gained so much weight! LOL Though I am half serious.
Most nights I get seven or eight hours in.
Sleep is so important for many reasons! I usually sleep well, and when I don't I know that I have to watch what I eat more carefully.
Dormir es necesario para estar sano. Buena entrada. Te mando un beso.
Generally I don't have issue sleeping.
Coffee is on and stay safe
Interesting to read Jan.
interesting - I certainly lack sleep and have a fat belly!
Interesting. If I am up later than usual for something the hunger comes on and I end up eating more that day than normal. Luckily I'm a good sleeper.
Thanks for the useful info. All the best!
I tend to eat more if I am not well rested. The body craves energy.
