Obesity can be treated mainly by diet, exercise and medication. But it is essential to have a sound psychological well-being in order to get a better outcome in the long term. The frequent mental health problems in obese patients, the neurobiological findings of food addiction and the reasons why clinicians involved in obesity treatment should change their attitudes were reviewed. The research on mindful eating is still in its infancy and the concept, principles and skills of mindful eating were investigated by literature reviews. Not only we would be able to control the body weight, but we would also have wholesome relationship with food by practicing mindful eating. Ideally it would also have further positive effects just like the other mindfulness-based interventions.
