The Anti-Jet-Lag Diet

Frequent travelers swear by this diet, created by scientists at the University of Chicago’s Argonne National Laboratory. Essentially a pretravel regimen, it suggests a four-day feasting-and-fasting program that ends upon arrival. Feast days mean lots of protein early in the day and a carbohydrate load in the evening, while fasting calls for three small, low-calorie meals. This coordinated eating plan speeds adaptation to new time zones by resetting our inner clocks and adjusting our biological cues. www.antijetlagdiet.com

Hotel Cures

Many hotels and spas now offer de-stressing jet-lag treatments to whip mind- and body-warped travelers back into shape. The VH Spa at Scottsdale’s Hotel Valley Ho (480-248-2000, www.hotelvalleyho.com) offers quantum biofeedback and acupuncture sessions that rebalance and reenergize, while the spa at the Watermark Hotel & Spa in San Antonio (210-396-5800, www.watermarkhotel.com) serves up mineral-loaded power drinks with names like Virtual Buddha. Yoga videos are de rigueur on televisions at all Hyatt hotels (www.hyatt.com) in the United States, and many hotels, such as the Fairmont Dubai (011-971-4-332-5555, www.fairmont.com/dubai), renew weary guests with pressure-point-oriented massages — our personal favorite is their Time Zone Rejuvenator.
