"We were new to the Internet and wanted a way to communicate with each other," Suzanne recalls. "We put it together as a tool to keep in touch on the Internet. We didn't think anyone would ever see it. We put up recipes and whatever else we thought could be useful. Eventually, it was discovered by other people who found the information useful, and it grew from there."

Today, www.3fatchicks.com is still going strong as they continue to share their own struggles while motivating other like-minded dieters to keep battling the bulge. They even released a book last spring, 3 Fat Chicks On A Diet: Because We're All In It Together (St. Martin's Press 2006).

A one-stop shop for dieters, 3 Fat Chicks On A Diet offers every weight loss tool imaginable -- from reviews to recipes to success stories. The Barnetts have created a site that has something for everybody, whether you're looking for low-fat, low-carb or any other pounds-shedding approach.

While many online programs promote one specific diet, the Barnett sisters are well aware that weight loss isn't a one-size-fits-all deal. In fact, while Suzanne, Jennifer and Amy maintain a unified front in their diet endeavors, they each rely on a different approach to shed the extra pounds. Amy, for example, underwent gastric bypass surgery while Suzanne relies on a Mediterranean style of eating. Working together, the slimming siblings lost an estimated 85 to 100 pounds each.
