CLEVELAND, OH - A new study in the "Journal of Consumer Research" says spending too much time on social network sites like Facebook and Twitter could ruin your diet plans. Researchers at the University of Pittsburgh teamed up with researchers at the University of Columbia and found that people who used social networking sites lost self control when it came to junk food. But they also found that people's self esteem was enhanced.

Researchers studied 84 people and divided them into two groups. One group looked at Facebook while the other spent their time surfing a news website. Amy Jamieson-Petonic, a registered dietitian from the Cleveland Clinic says, "What the research found was that the group that was on social media tended to eat higher fat, higher calorie foods, such as cookies. Whereas the group that was looking at news website were looking for healthier choices."

An easy way to not make bad food choices while online is to only eat in the dining room. Jamieson-Petonic says, "It's really easy to get distracted and be less mindful when you're on the computer than if you're sitting at the dining room table focusing on the food choices that you have, I mean it really is easy to get distracted and make unhealthy choices."
