Objective: The aim of this study was to evaluate the impact of mindfulness‐based interventions on psychological and physical health outcomes in adults who are overweight or obese.
Methods: We searched 14 electronic databases for randomized controlled trials and prospective cohort studies that met eligibility criteria. Comprehensive Meta‐analysis software was used to compute the effect size estimate Hedge's g.
Results: Fifteen studies measuring post‐treatment outcomes of mindfulness‐based interventions in 560 individuals were identified. The average weight loss was 4.2 kg. Overall effects were large for improving eating behaviours (g = 1.08), medium for depression (g = 0.64), anxiety (g = 0.62) and eating attitudes (g = 0.57) and small for body mass index (BMI; g = 0.47) and metacognition (g = 0.38) outcomes. Therapeutic effects for BMI (g = 0.43), anxiety (g = 0.53), eating attitudes (g = 0.48) and eating behaviours (g = 0.53) remained significant when examining results from higher quality randomized control trials alone. There was no efficacy advantage for studies exceeding the median dose of 12 h of face‐to‐face intervention. Studies utilizing an Acceptance and Commitment Therapy approach provided the only significant effect for improving BMI (g = 0.66), while mindfulness approaches produced great variation from small to large (g = 0.30–1.68) effects across a range of psychological health and eating‐related constructs. Finally, the limited longitudinal data suggested maintenance of BMI (g = 0.85) and eating attitudes (g = 0.75) gains at follow‐up were only detectable in lower quality prospective cohort studies.
Conclusions: Mindfulness‐based interventions may be both physically and psychologically beneficial for adults who are overweight or obese, but further high‐quality research examining the mechanisms of action are encouraged.
