Have you heard of the hunger hormone Ghrelin?

Ok - so I consider myself on top of health and wellness topics. I read a lot of newsletters, use Google Alerts to get breaking news about health and follow (mostly) healthy people on a variety of social channels. But it was only recently I saw Gherlin start popping up in various news or informative articles and the word was buried and used in an off-the-cuff kind of way. Like everyone was aware of this!
