Standing 'could help you slim', says study
Standing rather than sitting can help you burn calories, and possibly lose weight, according to a new study.
Stand for six hours a day and you could lose 2.5kg a year, researchers suggested.
The study, published in the European Journal of Preventive Cardiology, is based on a study of 1,184 people whose average weight was 65kg.
The US and Spanish researchers found that the difference in energy expenditure between sitting and standing was 0.15 kcal per minute. Over the course of six hours this could translate to 54 calories. And over a year this may translate to a 2.5kg weight loss, they said.
The effects were more pronounced in men than women.
Previous work has described how different muscles are used when standing. During standing, more muscles are tensed and stretched to fight gravity and bear weight.
However, they stressed that whether the additional expended energy would translate into long-term weight loss was yet to be proved, because standing for prolonged periods may lead to an increase in calorie intake as a result of more muscle activity.
Data was also needed on the long-term health implications of standing for extended periods, they added.
Senior author Professor Francisco Lopez-Jimenez, chief of preventive cardiology at the Mayo Clinic in Rochester, US, said: "Standing not only burns more calories, the additional muscle activity is linked to lower rates of heart attacks, strokes, and diabetes, so the benefits of standing could go beyond weight control."
