The next time you jump in your car, grab a subway or catch a bus to work, be careful about the types of foods you bring with you, as results of a new report point to the risks of longer commutes adding calories to your diet and inches to your waistline.

A new report released by the Royal Society for Public Health describes how commuters who consume foods high in fat and sugar-typically triggered by stress-can potentially add up to 800 calories weekly to their overall intake.

The report revealed that those living in England and Wales specifically face some of the longest commutes throughout the world, according to data from 2013. The average commute in both countries was 56 minutes that year, spent in cars, trains or buses.

According to the report, those living in London had the longest average commute at 79 minutes, exceeding average times in New York, Chicago and Los Angeles.
