If Your Body's on Another Time Zone...
Fine, get back on that Dreamliner. Pull another string of all-nighters. But then, to avoid the subsequent week of jet-lagged, sleep-deprived misery, stop eating for 16 hours. Researchers at Beth Israel Deaconess Medical Center. found that the fastest way to put a mouse’s circadian rhythms on a new (or correct) time zone was to reset its "food-related master clock." This requires a single cycle of starvation during the normal wake period, followed by a meal on the right schedule (Note: Although there have been no human trials, only anecdotal support, the researchers think this strategy may help people too.) Consult your doctor before fasting.
