"The problems with all the hormones is that they have other effects," said Rafael de Cabo, an investigator at the Laboratory of Experimental Gerontology, part of the U.S. National Institute on Aging.

There can be many possible unintended effects, de Cabo said. "Before you can even think of giving these to humans, you have to be sure it is safe and doesn't have other implications," he said.

"Any time you try to tweak the neuroendocrine system, all the knobs are interconnected, so if you move one up or down there is an immediate response from the rest of them," de Cabo said. "It is not a golden bullet or an easy shot to fix the metabolism by a single compound."
