Hungry? Get More Sleep.
Monday October 15, 2007
Sleep and obesity are closely linked. It's an endless cycle. People who don't get enough sleep, face changes in their blood chemistry that lead to an increased appetite. As they gain weight, they are more likely to suffer from sleep apnea and other sleep problems - causing an increase in appetite and more weight gain.
What happens is that during sleep leptin (a hormone that tells that brain you're "full") and ghrelin (the "hungry hormone") are regulated. If you don't have enough sleep, the balance between your "full hormone" (leptin) and your "hungry hormone" (ghrlein) becomes disrupted. In short - you have 18% less leptin and 28% more ghrlein when sleep is cut from 8 hours to 4 hours a night. This causes appetites to spike.
In one study, participants' sleep was cut back and they had a major spike (24%) in their cravings for sweets, cookies, chips and other snack foods.
If you are trying to lose weight, be sure that more sleep is part of your plan.
sighs..no findings on how come one can sleep so much and still be hungry all the time. someone help? is it zollinger-ellison's?
