Research Abstract	We analyzed the association between behavior rhythm and dietary rhythm and obesity using genetic-obese model mice, ob/ob mice. Our results indicated that total activity per day was decreased and behavior rhythm was changed in ob/ob mice compared with normal mice. Furthermore, total activity per day was decreased and behavior rhythm was changed in ob/ob mice fed on only light cycle compared with ob/ob mice fed on only dark cycle. These results suggested that behavior rhythm and dietary rhythm may be associated with abnormal internal secretion in ob/ob mice.
