So, wait. You mean to tell me that your newspaper ran the article but left out the part where they explain why sleep loss may lead to weight gain? That seems kind of weird and not at all very professional at all. But since I like to consider myself a professional, here is the reason why:
Scientists have found that sleep deprivation increases levels of a hunger hormone and decreases levels of a hormone that makes you feel full. The effects may lead to overeating and weight gain.
Now was that so hard?
