WWR Article Summary (tl;dr) Researchers found that by substituting standing for sitting for six hours a day, a 143.3-pound adult would expend an extra 54 calories in six hours. Assuming no increase in food intake, that would equate to 5.5 pounds in one year and 22 pounds over four years.
Standing instead of sitting for six hours a day could help people lose weight over the long term, according to a Mayo Clinic study published in the European Journal of Preventive Cardiology.
In recent years, sedentary behavior, such as sitting, has been blamed for contributing to the obesity epidemic, cardiovascular disease and diabetes, says Francisco Lopez-Jimenez, M.D., senior author and chair of preventive cardiology at Mayo Clinic. Population-based studies report that, in the U.S., adults sit more than seven hours a day. The range across European countries is 3.2 to 6.8 hours of daily sitting time.
The study examined whether standing burns more calories than sitting in adults in the first systematic review and meta-analysis (combining data from multiple studies) to evaluate the difference. The researchers analyzed 46 studies with 1,184 participants. Participants, on average, were 33 years old; 60 percent were men; and the average weight was 143.3 pounds.
“Overall, our study shows that, when you put all the available scientific evidence together, standing accounts for more calories burned than sitting,” says Farzane Saeidifard, M.D., first author and cardiology fellow at Mayo Clinic.
The researchers found that standing burned 0.15 calories (kcals) per minute more than sitting. By substituting standing for sitting for six hours a day, a 143.3-pound adult would expend an extra 54 calories (kcals) in six hours. Assuming no increase in food intake, that would equate to 5.5 pounds in one year and 22 pounds over four years.
