What this trial studies

This study evaluates a privacy-conscious wearable device designed to monitor eating behaviors in free-living individuals. Participants will wear the device for four weeks while logging their food and drink intake and engaging in unscheduled phone calls with a dietitian. The device captures images of the wearer’s head and upper torso, utilizing various privacy filters to protect identities. Participants will undergo training in a lab setting before taking the device home for the active weeks, with washout periods in between.

Who should consider this trial

Good fit: Ideal candidates include individuals with a BMI of 18.5 or higher who reside in the Chicago metropolitan area and can communicate in English.

Not a fit: Patients who are pregnant, breastfeeding, or have experienced significant weight fluctuations recently may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into eating behaviors, potentially leading to improved dietary interventions.

How similar studies have performed: While the use of wearable devices for behavior monitoring is gaining traction, this specific approach with privacy filters is relatively novel.
