There's Such Thing as a "Jet Lag Diet"—Here's Exactly How to Follow it

Jet lag might seem like an inevitable part of international travel, but doctor and nutrition expert Michael Mosley argues that doesn't have to be the case. Mosely, who is the behind the popular 5:2 diet, recently penned an article for the Mail on Sunday explaining his theory. 

"A few years ago, I discovered the joys of intermittent fasting and not only did I lose weight, but I found that my jet-lag was greatly improved," he said. It's not a coincidence—Charles Ehret, a researcher at the University of Chicago, started writing about the link between diet and jet lag in the 1980s. "Dr. Ehret suggested that you could reset your internal clock much faster if, for three days before flying, you alternate feasting and fasting," he explained. When the U.S. military put the theory to the test, they found those who followed the diet were more roughly seven times less likely to experience severe jet lag.
