For friends Talia, Sarah, Stephanie and Beth, sharing the latest news about celebrities, coworkers and friends comes as natural as breathing. "Gossip is a huge part of my life," says 27-year-old Talia. "I look forward to doing it every day." Stephanie, 29, agrees: "I can't imagine my life without gossip. I think it would be pretty boring."

These girls are not alone when it comes to talking about others, but such chit-chat can reach an ugly level if taken too far. "People by nature like to talk to one another," says life coach Harriette Cole, "but gossip is when it turns negative. It's that rude commentary that you would never say in front of somebody. If you don't have the courage to say it in front of the person, even if it's a celebrity, you shouldn't be saying it at all because it's negative and it erodes your relationship, your being, and also other people because it's energetic and it goes out into the universe."

To help rid themselves of some of that negative energy, the four friends agree to go on a gossip diet - seven days without one word of gossip. The girls agreed to document their week without rumors -- check out the video clip above to see how it impacts their lives.

Back in the studio, the women share what they learned. "I realized that I needed to implement a filter in my life," admits Talia. "Don't say things or write things just as they pop into my head. Think about -- am I going to hurt somebody? Do I know this to be fact? And is it my place to say it?"

Harriette says Talia is on the right track, explaining that there are four questions to ask yourself before sharing something with another person: "Is it true, is it kind, is it timely and is it necessary? If you can say yes to all four of those, then talk away!"

Harriette suggests that the friends could use the energy they once spent sharing gossip and put it to better use. "Imagine if the four of you started talking creatively," she says. "What are the creative ideas that you all have that you might be able to build some great business or charity or whatever instead of talking about other folks. Do something with your beauty and your creativity to make something for yourselves that will last for a long time."

Do you think you could survive a gossip diet?
