Obesity vaccine would suppress hunger hormone

The hormone ghrelin may have had an important evolutionary purpose (it lets us know that our stomachs need some food and may even help us sniff out some grub) but in these modern times when we no longer, for the most part, hunt or gather, ghrelin seems to be primarily a contributor to obesity. Now, in the latest chapter in the continuing saga of obesity treatments, a new vaccine is in the works that promises to suppress ghrelin and, researchers in Portugal say, make us no longer feel so hungry. The research is expected to be presented Sunday at The Endocrine Society's 93rd Annual Meeting in Boston. Story
