A consensus or society position rather than new primary data.
This critical narrative review synthesizes evidence on artificial intelligence, wearable devices, and virtual reality for precision obesity management, published between 2019 and 2026. While these technologies show promise for behavioral monitoring, personalized feedback, and engagement, the authors conclude that long-term clinical effectiveness remains uncertain due to heterogeneous evidence, methodological limitations in underlying studies, and insufficient clinical validation.
Critical narrative review. Published studies on artificial intelligence, wearable technologies, and virtual reality applied to precision nutrition and obesity management; population characteristics of individual studies not specified.. Intervention: Artificial intelligence, wearable devices, mobile health applications, and virtual reality interventions for obesity management and precision nutrition.
Wearables and mobile applications enable continuous self-monitoring of physical activity, dietary intake, sleep, and physiological measures Artificial intelligence may improve dietary personalization, risk prediction, glycemic control, and adaptive feedback Virtual reality offers an immersive approach to behavioral and cognitive mechanisms related to overeating including cravings, food cue reactivity, and inhibitory control

Clinicians should recognize that digital health technologies for obesity management are investigational and show potential but lack robust long-term clinical outcome data. Current evidence supports their use as adjunctive tools for behavioral monitoring and engagement while awaiting larger, longer-duration randomized trials.
A critical narrative review synthesizing heterogeneous evidence on emerging digital health technologies for obesity management, acknowledging substantial limitations and calling for future research rather than establishing a definitive clinical recommendation.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Background: Obesity is a chronic, multifactorial disease that demands personalized and sustainable management approaches. Digital health technologies, such as artificial intelligence, wearable devices, mobile health apps, and virtual reality (VR), may support obesity care by providing enhanced behavioral monitoring, personalized feedback, and patient engagement. Objective: This critical narrative review discusses the current evidence on artificial intelligence, wearable technologies, and VR in the context of precision nutrition and obesity management and their possible clinical applications and limitations. Method: A critical narrative review was conducted using peer-reviewed literature published between 2019 and 2026 and identified through PubMed and Google Scholar. Search terms included combinations of “precision nutrition,” “personalized nutrition,” “obesity,” “weight management,” “metabolic health,” “digital health,” “artificial intelligence,” “machine learning,” “mobile health,” “wearable devices,” and “omics” using Boolean operators. Evidence from randomized controlled trials, systematic reviews, meta-analyses, and key conceptual studies was critically synthesized due to substantial heterogeneity in interventions and outcomes. Result: Wearables and mobile applications can enable continuous self-monitoring of physical activity, dietary intake, sleep, and physiological measures. Artificial intelligence may improve dietary personalization, risk prediction, glycemic control, and adaptive feedback. VR offers an immersive way to tackle behavioral and cognitive mechanisms related to overeating such as cravings, food cue reactivity, and inhibitory control. However, the evidence is heterogeneous, with many studies limited by short follow-up periods, small samples, variable adherence, and insufficient clinical validation. Conclusions: Artificial intelligence, wearable technologies, and VR are promising tools for precision obesity management, but their long-term clinical effectiveness remains uncertain. Future research should prioritize adequately powered trials, longer follow-up, standardized outcomes, transparent algorithms, ethical data governance, and integration with multidisciplinary nutrition and obesity care.
