The next time you have to cross several timezones, you might not have to put up with the sleep disturbances, headaches and other ill effects known as jet lag. Follow this four-day anti-jet-lag diet before your trip to reset your inner clock in advance.
The Argonne Anti-Jet-Lag Diet was developed in the '80s at the US Department of Energy's Argonne National Laboratory. Many travellers swear by it, and a military study in 2002 found those who went on the diet were seven times less likely to experience jet lag when travelling west and 16 times less likely when travelling east.
The diet consists of alternating feast days (lots of proteins and carbs) and light fasting days (foods like broths, salads and toast), as well as drinking coffee and other caffeinated beverages only at certain times.
It sounds tough, but if you're going on a long trip, it might well be worth it, and maybe even easier than fasting completely for 16 hours.
