Pancreatic polypeptide

The future fight against fat

Clinical trials will soon be under way for a nasal spray, developed by Compellis Pharmaceuticals in Somerville, MA, that blunts your sense of smell and taste, making food less appealing. In animal studies, rats gained 25% less weight after sniffing the drug; FDA approval is expected by 2010.

Scientists at Imperial College London have developed an appetite-suppressing compound that may be injected into foods and on the market within 5 to 8 years. It contains pancreatic polypeptide--a natural hormone that triggers fullness.
