Twitter use found to help to maintain weight loss goals:

After following 96 subjects over six months as they tried to eat healthier
and stick to exercise, University of Carolina researchers found that those
that used Twitter regularly actually lost more weight.

In fact, for every 10 Twitter posts, they lost an additional .5 percent
weight loss, according to the scientists from the university’s Arnold
School of Public Health. The study has just been published in*Translational
Behavior Medicine* if you want to read it yourself.
