People who cycle, walk or catch the train or bus to work keep more weight off than commuters who travel by car, a large UK study has found.

The results come from 150,000 UK adults aged 40 or older who agreed to be measured and weighed and fill in a survey about their typical journey to and from work.

Cycling came out as the best activity for staying trim, followed by walking.

But even those who used public transport were leaner than car users.

The authors of the Lancet Diabetes and Endocrinology study say the findings show even a little physical activity is better than nothing at all.

They reached their conclusions by comparing the bodyweights and lifestyles of the 72,999 men and 83,667 women in their study.

Even when they factored in differences such as leisure-time, exercise, diet and occupation, the trend between commute method and bodyweight remained.

And for both cycling and walking, greater travelling distances were associated with greater reductions in percentage body fat.

By their calculations, an "average" height man would weigh around 5kg (11lbs) less if he were to cycle rather than drive to work each day.

Likewise, the average height woman would weigh 4.4kg (9.7lbs) less.

iWonder: What's the easy way to get healthier?

In the study, 64% of men and 61% of women commuted by car, while 4% of men and 2% of women reported cycling or doing a mix of cycling and walking.

In England and Wales, 23.7 million people regularly commute to work and around two-thirds do so by car, according to census data.

Study author Dr Ellen Flint, from the London School of Hygiene and Tropical Medicine, said: "We know that physical activity can help prevent obesity - absolutely we do - and yet, two thirds of the UK population don't achieve weekly recommended levels of physical activity.

"This study shows basically that people who do manage to build some level of physical exertion into their commute, even if it's just walking to a bus stop or cycling a short distance, they tend to be less heavy and have less body fat than people who drive all the way to work."

'It's a win win'

She said it was important that policy makers and town planners make it easy for people to walk and cycle to work.

"It's a win, win really for public health and the environment," she said.

Justin Varney, deputy director of Health and Wellbeing at Public Health England, said: "Physical activity can play a role in maintaining a healthy weight, and helps to prevent or manage over 20 long-term conditions such as coronary heart disease, diabetes and some cancers.

"Walking and cycling are some of the easiest ways for people to incorporate physical activity into their daily lives and it is never too late to start."
