Shots may help you lose that pot belly -report

WASHINGTON (Reuters) - Researchers have figured out how to remove fat from one part of the body and make it grow in another part -- at least in mice -- and say their findings could benefit health as well as beauty.

Their findings also shed light on how and why stressed-out people so often gain weight.

"We don't think this is something that would be used for gross obesity, but for reshaping the body for use with pockets of fat ... that would be all very good," said Dr. Zofia Zukowska of Georgetown University Medical Center in Washington, who led the study.

Their findings are based on a naturally produced chemical messenger or neurotransmitter called neuropeptide Y, or NPY -- long linked with appetite, weight gain and obesity.

Zukowska said her findings in mice suggest that NPY helps make some body fat more dangerous than other kinds. Controlling it could help slow some of the more dangerous side effects of obesity such as heart disease and diabetes, her team reported in the journal Nature Medicine.

Manipulating NPY offers a new tool for plastic surgeons. "You could take the fat from your buttocks and put it in your breasts and cheeks," she said.

NPY attaches to a receptor, a molecular doorway, in fat cells that is called neuropeptide Y2 receptor, or Y2R. It activates fat cells and some of cells in the blood vessels found in fat tissue.
