Values are presented as mean±standard deviation. Rats were divided into three groups: high-fat diet (HFD), combined high-fat diet and exercise (HFD+EXE), and dietary adjustment (DA) groups.

^a)The data were analyzed using the Duncan test.

^b)No stastically significant difference among group.

^c)FER=body weight gain (g/wk)/food intake (g/wk).
