| Outline of Final Research Achievements |
This study was undertaken to clarify a mechanism for the control of feeding rhythm or voluntary exercise by ghrelin, an appetite-promoting hormone, and a putative role of hits peptide in the crosstalk of feeding and exercise. Furthermore, we evaluated autonomic nervous activity in obese patients in relation to abnormal binge eating behavior often observed in these subjects. As a result, we demonstrated a crucial role of ghrelin surge in the maintenance of diurnal rhythm of either feeding or energy metabolism and in the formation of motivation for voluntary exercise. In obese patients, parasympathetic activity was suppressed during night, suggesting a possible contribution to blunted quality of life in these subjects.
