Using Twitter may help people lose weight by providing them with social support, researchers report.
A six-month study of 96 overweight and obese people found that their use of Twitter — a popular online social networking service — as part of a weight-loss program improved their chances of shedding excess pounds.
“The results show that those who regularly utilized Twitter as part of a mobile weight-loss program lost more weight,” study leader Brie Turner-McGrievy, of the department of health promotion, education and behavior, at the Arnold School of Public Health, University of South Carolina, said in a university news release. ...
Overall, both groups of participants lost an average of 2.7 percent of their excess weight after six months. But those who used Twitter were more successful at losing weight, and the researchers said that every 10 posts to Twitter corresponded with about a 0.5 percent weight loss.
