Exploring Sensing Technologies for Tracking Healthy Eating Behaviors: Systematic Review
Bibliographic record
Abstract
Sensor-based technologies for healthy eating have gained attention in human-computer interaction research. With the prevalence of diet-related health issues such as obesity and diabetes, innovative interventions providing personalized dietary feedback are increasingly needed. Sensor-based technologies offer real-time monitoring of dietary habits. We reviewed 28 articles, published between 2014 and 2024, to uncover the state-of-the-art and research gaps. Sixteen articles (57.1%) reported on effectiveness: seven measured by machine learning model performance and nine through user study evaluation. We identified several eating behaviors that were supported: adequate food intake, meal size and quality, eating posture, swallowing sounds and difficulties, eating styles, and pace. These behaviors were associated with conditions such as diabetes, post-stroke issues, cardiovascular diseases, obesity, and binge eating. Limitations included little to no interventions for life-threatening conditions. Our findings present opportunities to develop tailored sensor-based interventions for various diet-related issues.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
