| Outline of Final Research Achievements |
Twenty-two obese subjects were randomly assigned to two groups of mindfulness eating meditation training groups (MB) and health education groups (HE), and how body mass index (BMI), eating behavior, psychological symptoms, serum protein, and brain function and brain activity changed across interventions at baseline, 7 weeks, 14 weeks, and 6 months. The results showed that both groups had a higher BMI than the baseline group. The results showed no difference between the two groups, although the main effect of BMI at each time point was significant in both groups. Statistically significant differences were found for depressive symptoms and positive affect and leptin. In addition, the MB group showed an increase compared to the HE in resting brain functional connectivity in the central postcentral gyrus and cerebellum of the sensorimotor network and in the inferior frontal gyrus and left frontal pole of the language network.

| Academic Significance and Societal Importance of the Research Achievements |
肥満症はその病態から身体的、心理的あるいは時間的負担によってしだいに治療意欲が低下し、通院治療の中断や脱落という問題が浮き彫りになる。もう１つの問題は、肥満症の中には、定期的な受診でたとえ順調に減量したとしても、多食が再現し体重がリバウンドし、それを繰り返すケースも少なくない。２つの問題解決に近づく方法に、マインドフルネス食瞑想トレーニング（MB-EAT）をオンラインで行う、遠隔によるMB-EATがある。現時点で肥満症の遠隔MB-EAT介入研究および肥満に関連するレプチンなど血清タンパクの変化や脳機能画像を扱った研究は見当たらない。このことから、本研究の学術的・社会的意義はある。
