A fifty year old cyclist weighs about five kg less than his car driving colleague. This is the result of a British study on the relationship between obesity and the way they are traveling to work.
This is the result of the most richest study ever on this subject , published in The Lancet Diabetes & Endocrinology journal. The research was conducted by the London School of Hygiene & Tropical Medicine. In this study they used data from 150,000 people in the UK Biobank, which includes data from half a million people aged 40 to 69.
The largest differences in body weight and BMI were found for adults who go to work by bicycle, compared with commuters traveling by car . The average man (53 years in the study) weigh 5 kg less. In average a women aged 52 cycling to work weigh 4.4kg less than her colleague driving a car to work.
The relationship between body weight and the mode of transport is independent of other factors such as income, living in disadvantaged neighborhoods, education, alcohol consumption, smoking, physical activity and overall general health.
