Adherence
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.
Wearable sensors can track your eating habits automatically by detecting gestures, chewing sounds, and swallowing. While current prototypes may be uncomfortable, they offer a more accurate and continuous view of your diet than manual logging.
ModerateSupportsMEDIUM confidence
Using the classification procedure, we obtained 94 percent accuracy overall... For classification of all foods, we obtained accuracy of 80 percent... discriminated between two types of swallowing... with an overall accuracy of 73 percent.
Why this rating
Based on small-scale prototype studies (students, small N) rather than large clinical trials.

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
- 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.Moderate
