How to beat jet lag by eating

Published at 4:06pm 6th June 2017.

It is claimed that regulating meal times could be the answer to getting over jet lag.

In the first human study of its kind, researchers at the University of Surrey, changed the meal times of volunteers.

They then took blood samples and fat biopsies.

What they found was that delaying meal times led to delayed rhythms of blood sugar.

According to the researchers, it could mean shift workers and those suffering jet lag could time their meals in such a way as to resynchronise their body clocks.

It is all about circadian rhythms, which are approximate 24-hour changes governed by the body's internal clocks and determine many physiological processes in the body.

Volunteers were provided with three meals; breakfast, lunch and dinner.

In the first phase of the study, the first meal was provided 30 minutes after waking, with later meals at subsequent five hour intervals.

In the second phase each meal was delayed by five hours after waking. 

Lead investigator of the study, Dr Jonathan Johnston, from the University of Surrey said: "It has been shown that regular jet lag and shift work have adverse effects on the body, including metabolic disturbances.

"Altering meal times can reset the body clocks regulating sugar metabolism in a drug free way.

"This will help us design feeding regimes to reduce the risk of developing health problems such as obesity and cardiovascular disease in people with disturbed circadian rhythms."
