"CHICAGO (Reuters) - Starving yourself before a long flight may help prevent jet lag, U.S. researchers said on Thursday.Link
Normally, the body's natural circadian clock in the brain dictates when to wake, eat and sleep, all in response to light. But it seems a second clock takes over when food is scarce, and manipulating this clock might help travelers adjust to new time zones, they said.
"A period of fasting with no food at all for about 16 hours is enough to engage this new clock," said Dr. Clifford Saper of Harvard Medical School, whose study appears in the journal Science.
He said a person from the United States traveling to Japan must adjust to a 11-hour time change.
"Because the body's clock can only shift a small amount each day, it takes the average person about a week to adjust to the new time zone. And, by then, it's often time to come home," Saper said in a statement."
