There are many chemicals involved in the brain and body that signal when hunger is present or the sensation of fullness ("satiety) occurs. Aside from serotonin, two of these important chemicals are leptins and ghrelins. Leptins are manufactured from fat cells and when levels are high, this signals the body that enough fat is present and therefore more eating is not required. Ghrelins are made in the stomach cells and conversely, high levels tell the body to keep feeding.
Studies have demonstrated that altered sleep patterns, particularly insomnia, alters the balance of these chemicals and this may explain why people who have difficulty sleeping often have difficultyu controlling their appetite at night.
There is research underway to try to figure safe ways to raise leptin levels which in turn, would make people feel less hungry.
Getting a good night's sleep is essential for many body functions, and this data is yet another reason why poor sleep patterns can adversely affect the body.
Tomorrow local CBS, WUSA, is coming out to film a segment about our program. One segment will be shot at Burke Lake Park with a bunch of us going over there for a midday walk. If you happen to have the day off tomorrow and would like to join us (this will be your chance to be discovered!!!!) PLEASE call us for details. We would love to see you there.
