Fasting to Beat Jet Lag

Steve Hendricks, writing for Harper’s:

The Argonne Anti–Jet-Lag diet, as the putative antidote is known, was devised in the 1980s by the late Charles Ehret, a “chronobiologist” at the Argonne National Laboratory in Illinois who discovered that our biological clocks are cued in part by when and how much we eat. After experimenting on protozoa, rats, and his eight children, Ehret recommended that the international traveler, in the several days before his flight, alternate days of feasting with days of very light eating. Come the flight, the traveler would nibble sparsely until eating a big breakfast at about 7:30 a.m. in his new time zone — no matter that it was still 1:30 a.m. in the old time zone or that the airline wasn’t serving breakfast until 10:00 a.m. His reward would be little or no jet lag.

Research at Harvard suggests you can get the same results by simply fasting for 12-16 hours.
