Purpose

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.

Just-in-time Adaptive Intervention
A sensor device called an Automatic Ingestion Monitor (AIM) will be worn on eyeglasses to monitor eating. Information from the device will be used to send messages to a smartphone to change eating behavior.
  • Behavioral: Eat Less Intervention
    A sensor worn on eyeglasses monitors eating and provides messages to a smartphone when eating occurs to prompt small reductions in the amount of food eaten.
  • Behavioral: Eat Slower Intervention
    A sensor worn on eyeglasses monitors eating and provides messages to a smartphone when eating occurs to prompt small reductions in the rate of eating.
