Background: In the treatment of obesity, coordination of proper dietary and behavioral modification is considered essential. Recently, a novel behavioral modification method, Neurofeedback training system that based on biofeedback of brain wave was introduced. In previous studies, Neurofeedback systems had been proven effective in some medical field such as emotional liability, seizure disorder, sleep disorder, epilepsy, etc. and expected to have some beneficial effects on the treatment of subjects with obesity.
Methods:Total 15 Obese (BMI over 25 kg/m2) Korean women who failed to 12 week medical nutritional therapy were enrolled this study. All study subjects per-formed Neurofeedback training once a week and monitored diet related behavior for 8 weeks. Anthropometric data, serum markers, and questionnaires for dietary related be-havior were also collected before and after intervention.
Results: After 8 weeks intervention, mean body weight and BMI were not changed sig-nificantly among the subjects. However, mean total fat proportion, fasting plasma glucose and insulin concentration were significantly changed. Moreover, in eating pattern questionnaire and diet quality indices analysis, cognitions about dietary methods and regu-larity, and energy from carbohydrate intake were also significantly changed before and after Neurofeedback intervention.
Conclusion: In obese subjects, Neurofeedback training could be effective auxiliary to improve dietary and behavioral intervention.
