Conversational Agents Improve Dietary Behaviors Modestly
A systematic review published in Journal of Medical Internet Research (2025) evaluated conversational agents (CAs) for dietary behavior change across 11 references (10 studies, ~20–480 participants) identified from five databases. It found modest improvements in fruit and vegetable intake, Mediterranean diet adherence, nutritional knowledge, physical activity, and modest weight loss (RCT: −2.1 cm waist; P=.003), but outcomes varied with high attrition and limited social support.
Key Points
- 1Finds modest dietary improvements, including increased fruit/vegetable intake and Mediterranean diet adherence.
- 2Highlights personalized, real-time CA support as a mechanism to enhance engagement and nutritional knowledge.
- 3Urges larger, longer, standardized trials and engagement strategies to establish scalable, evidence-based CA interventions.
Scoring Rationale
Systematic, peer-reviewed synthesis with practical recommendations, limited by small samples, heterogeneous methods, and variable outcomes.
