Lack of Sleep Disrupts Weight Loss

Posted Oct 30 2008 10:39am

he less you sleep the greater the likelihood that you will gain unwanted body weight. Several studies conducted at University Medical Schools have repeatedly shown that lack of sleep affects hormonal balance that lets your stomach know if it is full. This correlation which has been tested to be very reproducible in the general population is now convincing hardcore medical fact. So if we look at our American society who is sleep deprived and overfed, is it any wonder that obesity is at epidemic proportions?

In another medical study they found that people who slept 2-4 hours per night were 73% more likely to become obese than normal sleeps The 2 culprit hormones are the ever famous Leptin and Ghrelin. Leptin found in fat cells signals the body that it has insufficient metabolic reserves and needs to eat more calories. Ghrelin on the other hand is found in the stomach and triggers your appetite. So the more Grehlin you have the greater your appetite!

Large NIH studies looked at Leptin and Ghrelin in 1024 subjects who slept 5 hours and 8 hours and found a 15% increase in both Leptin and Grehlin. So individuals never felt full and always felt hungry!

So, the moral of this story is get your but in bed at a respectable time and always strive to get 7 or more hours of sleep. Again, another needed discipline in our lives.
