Adherence
Continuous, location-independent monitoring via on-body sensors is superior to ambient-embedded sensors for capturing real-world eating behaviors, including snacks and meals outside the home.
To get a complete picture of your diet, tracking must happen everywhere you go, not just at home. On-body sensors provide this continuous, location-independent monitoring.

Solutions that depend on a particular environment—such as the home—would miss snacks, let alone entire business lunches. Such partial coverage severely limits the effect of behavior coaching...

More from this paper
- Self-reported dietary monitoring is highly inaccurate, with estimations ranging from 50% under to 50% over actual intake, making it an unreliable tool for weight management.Good
- On-body sensors (inertial, acoustic, physiological) can accurately detect eating events (gestures, chewing, swallowing) and classify food types, offering a continuous alternative to manual logging.Moderate
