Theres hope for a new weapon in the battle of the bulge. On Monday, Scientists reported success with an experimental vaccine to fight obesity.
Researchers vaccinated rats against a "hunger hormone" called ghrelin. The rodents ate whatever they wanted without gaining fat.
According to Dr. Kim Janda of the Scripps Research Institute in La Jolla, California, more research and data will be needed before an obesity vaccine is widely tested in humans.
The next, in a long list of steps, will be to see if already obese rodents lose weight when given the vaccination.
