Clinical Trial Summary

This is a NCI funded study which will develop and evaluate a cell phone application (mDIET) that can be used as an assessment and intervention tool to improve dietary behaviors and thus reduce weight in overweight and moderately obese (BMI 25-34.9) men and women ages 25-55.

Description:

This research will develop a technologically advanced system for monitoring and intervening on diet behaviors (e.g., food intake, weight). Interventions aimed at dietary change are missing a comparable, portable tool. Mobile technologies can help fill this gap by providing portable connectivity to expert systems that create specific tailored diet goals based on participant profiles. The expert system can 'push' intervention messages throughout the day during critical point-of-decision moments to aid in decision making among users. The portable device can 'pull' information through prompts and easy-to-use recording. This ecological momentary assessment + ecological momentary intervention format may further encourage healthy behaviors by prompting at critical decision points to improve dietary behaviors.

Eligibility

Inclusion Criteria:

• Participants will be included if they:
