Sensor-based Just-in Time Adaptive Interventions (JITAIs) Targeting Eating Behavior

Description

The purpose of this study is to determine whether a sensor device called an Automatic Ingestion Monitor (AIM) that is worn on eyeglasses can be used with a smartphone to change eating behavior. Participants will wear the device for one week of no-intervention observation. They will then test behavioral interventions focused on eating for two weeks. The researchers hypothesize that messages sent to a smartphone that are based on information from the AIM can reduce the amount of food that is eaten and slow eating.
