Some believe PYY may be one of the body's natural signals to the brain telling people they are full and should stop eating.

In 1986, Dr. Dvorak went on to demonstrate in the journal Cancer Research that VPF was secreted by a variety of human tumor cell lines and proposed that VPF was in part responsible for the abnormal vasculature seen in human tumors. As a result, he and other investigators demonstrated that VPF...New findings help explain how brain pathways control body weight
