Expatriate medical insurance policyholders who are trying to stay fit in order to prevent other health problems have been advised that gentle walking is an effective weight loss aid.
According to Maria Castellina, a spokesperson for the Ramblers association, walking one mile can burn off 100 calories.
"Making simple differences to your everyday routine, like walking to work rather than taking the bus, can help you to control your weight and even save a few pennies too," she pointed out.
Taking up gentle exercise does not mean that international health insurance customers have to spend a lot of money on special equipment either, Ms Castellina explained.
"If you walk regularly it is worth investing in a good pair of walking boots. However, if you're just starting out, or you're walking in cities or on good paths, then often a comfortable pair of trainers will be fine."
Her suggestions come after research published in The Physician journal and Sportsmedicine revealed that obese individuals are more likely to pinpoint exercise as a trigger for asthma.
