Mindfulness, as the awareness that emerges through purposely and non-judgmentally paying attention to the present moment, has attracted increasing attention from researchers on eating behavior. After reviewing and summarizing pre-existing studies, the present study finds that mindfulness plays an important role in correcting unhealthy eating behaviors,and awareness, acceptance and disidentification are its functional mechanisms. Besides, existing mindfulness-based methods for correcting unhealthy eating behaviors can be divided into two major categories of mindfulness state intervention and mindfulness-based clinical therapy. Future research needs to further explore the role of mindfulness in healthy eating behavior, investigate the influence of mindfulness on eating behaviors from the perspective of life cycle, explore the functional mechanisms of mindfulness based on thought suppression, and test the boundary of correcting effects of mindfulness on unhealthy eating behaviors.
