"She told me that her tried-and-true trick was not eating in-flight. Basically, at super high altitude, your digestive system shuts down completely. Someone said to me it’s like being under anesthesia."
"So when you get off the plane, everything restarts and [your digestive system] has so much more work to do and so it makes you more tired."
You would think that someone with so much in-flight experience would know a thing or two, but scientists have clapped back, claiming that there is little evidence to back up her claims.
I don't know about you, but I've definitely been hungry on every overseas flight I've ever taken. Surely that's a sign my digestive system hasn't shut down.
Although, it could be that many of us are just forcing down food simply because we're locked in a big steel tube and we're just bored?
Then again, nutritionists have contradicted Ms. Briggs's claims. Registered dietitian Carolyn Pallister reacted by saying the following:
"Suggestions that your digestive system shuts down during a flight has no scientific foundation. By restricting yourself and not eating for long periods of time on a long flight you are likely to feel weak, shaky, and could even suffer from headaches and low mood."
