Summary
Mindfulness-based interventions significantly reduce binge eating behaviors. This review found large effects, though high heterogeneity warrants further research into these effective treatments.
Area of Science:
- Psychology
- Clinical Psychology
- Behavioral Science
Background:
- Binge eating is a significant concern, with mindfulness-based interventions (MBIs) emerging as a promising treatment approach.
- A comprehensive summary of MBIs' effectiveness for binge eating is lacking.
- This study addresses the need for a systematic review and meta-analysis of MBIs for binge eating disorder.
Purpose of the Study:
- To systematically review and meta-analyze the existing literature on mindfulness-based interventions for binge eating.
- To determine the overall impact and magnitude of MBIs on binge eating behavior.
- To identify potential moderators and mediators of treatment effects.
Main Methods:
- A systematic search of PubMed, Web of Science, and PsycINFO was conducted.
- Keywords included binge eating, mindfulness, meditation, mindful eating, Acceptance and Commitment Therapy, and Dialectical Behavior Therapy.
- Nineteen studies met inclusion criteria for the meta-analysis, with random-effects models used to pool effect sizes.
Main Results:
- Mindfulness-based interventions demonstrated large to medium-large effects in reducing binge eating.
- Within-group analysis showed a large effect size (Hedge's g = -1.12).
- Between-group analysis also supported significant reductions in binge eating (Hedge's g = -0.70), despite high statistical heterogeneity (I(2) = 93% and 90%).
Conclusions:
- Mindfulness-based interventions are effective in reducing binge eating behaviors.
- The significant effects observed suggest MBIs are a valuable therapeutic option.
- High heterogeneity indicates the need for further research to understand variability in treatment outcomes and optimize interventions.

Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
