This study aimed to conduct a meta-analysis of the effects of mindful eating interventions on weight, BMI, eating behaviors and negative emotions. A total of 27 studies using randomized controlled trial were included in the analysis. Results showed that the effect of the mindful eating intervention on weight, BMI, eating behaviors and negative emotions was significant and small-medium. Age, interaction characteristics, types of control, and statistical analysis methods can moderate the effectiveness of mindful eating intervention.
