"Studies have linked poor sleep to obesity and other health problems, and now new research suggests a reason why.Two opposite, diametrically opposed explanations for the same finding.
The study, of 38 men with and without chronic insomnia, found that those with the sleep disorder had 30 percent lower nighttime levels of the hormone ghrelin, which is involved in appetite control...
...Ghrelin is secreted by the stomach to boost appetite.
In this study, men with chronic insomnia had lower overnight levels of ghrelin compared with their healthy counterparts. While that might seem like a good thing, the findings actually point to a problem in ghrelin regulation in men with insomnia, according to Motivala.
It's possible, he explained, that insomnia patients' ghrelin levels are lower than normal at night, but elevated during the day -- possibly boosting appetite.
On the other hand, he added, people with chronic insomnia may have consistently lower levels of the hormone, pointing to general dysregulation in how ghrelin is 'expressed' in the body."
"It's possible" that this is all crap. (likely)
"On the other hand," realizing that it's all crap puts no money in the hands of researchers. (certain)

backwards. Weight regulation disordered people have a high sensitivy to ghrelin. When ghrelin spikes we sleep uncomfortably (lacking REM sleep especially) We eat to keep the ghrelin levels down.
So cool when ghrelin leves spike we are not only sensitive to the hunger it creates but it affects our sleep as well creating insomnia in some.
