The Impact of Mindfulness Interventions upon Visual Attention and Attentional Bias Towards Food Cues: A Systematic Review.

Background/objectives: The so-called 'Western diet' characterised by the frequent consumption of high energy-dense (HED) food is linked with overeating, obesity, and an array of physiological and weight-related health complications. Attentional biases to HED food, which have been identified as a key mechanism promoting overeating, arise when reward-driven automatic processes impair the internal states responsible for regulating hunger and satiety. Emerging mindfulness-based interventions show promise in attenuating attentional biases by training controlled processes and enhancing the self-regulatory mechanisms required to override reward-driven automatic processing.

Methods: Following PRISMA 2020 guidelines and PICOS strategy, this systematic review collates and synthesises current research on the impact of mindfulness interventions on visual attention and attentional bias to food cues in adults. Searches were conducted in Web of Science, PubMed, Scopus, Springer Nature, MEDLINE, Embase, and CINAHL in September 2025.

Results: Findings obtained from six eligible studies were mixed indicating that mindfulness interventions significantly reduced attentional bias to HED, whereas other interventions indirectly enhanced self-regulatory systems such as hedonic hunger and craving without directly modifying attention. Additional findings highlight reductions in physiological reactivity, increased interoceptive awareness, and savouring.

Conclusions: Overall findings suggest that mindfulness-based practices hold preliminary but promising potential to subdue attentional biases to HED food and disrupt unhealthy eating habits influenced by the Western diet. However, the limited number of studies, small sample sizes, methodological heterogeneity, and lack of mechanistic clarity indicate that such conclusions should be interpreted with caution. More robust and standardised research is warranted to determine whether mindfulness can produce durable, real-world behavioural change.
