In case you needed another reason to use social media, researchers at the University of South Carolina have discovered that using a Twitter support group may help individuals achieve those challenging weight loss goals. The study’s findings showed that those who participated in a weight loss program overall lost more weight when they used the site to receive and share information and encouragement. The research team found that every 10 tweets corresponded with about 0.5 percent weight loss. The Twitter community provides an alternative to the traditional face-to-face weight-loss support group that may prove more cost-effective and less time-consuming. Researchers plan to examine how other social media sites function as health support systems and how to best tailor messages to give people the type of weight loss intervention they need.
