Body weight and organ weight
The change in body weight of each group is shown in Fig. 2. The effect of each treatment appeared statisti- cally significant after 7 d or later in the 10% DR and 30% DR groups, and after 12 d in the capsiate group. The average body weights of the capsiate, 10% DR, and 30% DR groups were respectively 3.2, 4.5, and 9.2 g less than that of the control group. As was the case for the body-weight gain, both capsiate and dietary restriction reduced the body-fat accumulation (Table 1). The relative weights of perirenal fat and epididymal fat in the capsiate, 10% DR, and 30% DR groups were significantly lower than that in the control group. In addition, the inhibition of body-fat gain in the 30% DR group was significantly greater than those in the capsiate and 10% DR groups. The relative spleen weight in the 30% DR group was significantly lower than those in the other groups, although there were no differences for muscle, liver, heart, kidney, inguinal fat, and IBAT among the groups.
