The study plans are to develop and test the efficacy of a practical, structured, and time-limited behavioral intervention (HealtheLifestyle Program) as a supplement to standard HealtheTech products. Approximately 130 participants will be recruited and randomized to either the HealtheTech Program (focusing on calorie and exercise goals using the BalanceLog for tracking), the HealtheLifestyle Program (using step counters, monthly email letters and calls providing information on activity, nutrition, and weight loss), or a delayed treatment program (after 3 months undergo the intervention above).
