A new study conducted at the University of North Carolina at Chapel Hill found that help in losing weight may be as close as the earbuds on your MP3 player. What they found was that a person using an MP3 player and earphones creates a more personal and intimate environment for listening to enhanced podcasts that engaged the listener while aiding them with their behavior modification. The [MP3 player] technology has some advantages over the Internet,” Turner-McGrievy said. “It feels more personal when someone is using earphones, as if someone is speaking directly to you. We want to take advantage of that intimacy and tailor messages that will bring success to people looking for ways to reach a healthy weight. The study participants listening to the enhanced podcasts lost an average of 6.4 pounds in twelve weeks.
