Before joining eDiets, consumers fill out a free diet profile which takes into account the person's current weight, height, age, gender, food preferences, activity level and other specifics to select the most appropriate eating regimen.

Once an individual has completed the Diet Needs Analysis profile and joined the program, he or she receives a personalized meal plan, complete with shopping lists, recipes and weekly menus. In addition, the eDiets member also receives unlimited access to the online support boards, live nutritionists and other trained professionals who will provide the client with guidance to achieve his or her goal. For many, it's like having a personal dietitian at their fingertips 24/7.

eDiets.com boasts a staff of trained professionals including nutritionists, fitness experts, psychologists, eating disorder specialists and more. Spend some time browsing through the website and you're sure to find something for every body. The cost of the plan averages $3.99 a week, which is affordable compared to other brick-and-mortar programs.

By following the any one of the plans offered by eDiets, you can expect to lose up to 10 pounds in five weeks. Unlike other weight-loss centers that aren't readily available at any given moment, eDiets is always open -- day or night. Whether it's an expert meeting, a chat room or an exchange on the many bulletin boards, there is always someone around to lend support.
