Cell Groups are expert-facilitated groups of 12 people who come together each week over 16 weeks via phone and Web 2.0 tools. For 90 minutes, they discuss their challenges and share insights. Activities include contact with other cell members and Web-based homework activities throughout the week.

Some Cell Group topics include: "Emotional eating and its relationship to weight loss," "Depression: The Way Out," "Conquering anxiety," "Anger management," and "Building healthy marriages."

Cell Groups are highly effective and efficient at creating individual lifestyle changes. They are an opportunity to connect people with common health concerns and have them work together towards the same goal. Members hold each other accountable for their behavior so there's more motivation to succeed, and participants have an opportunity to practice lifestyle changes with support over a long period.
