Abstract
The purpose of this study is to investigate the effect of high-fat diet to appetite and physical activity. Ten 9week-old rats were divided into two groups: 5 rats took control diet and other 5 took high-fat diet for 50weeks. They ate freely and voluntarily ran on the wheel. Energy intake of the rats in high-fat group had strong correlation to physical activity but not in control group. The rats in high-fat group were heavier than those in control group, judging from the energy intake. The rats were most active when they were about 15 week-old. Tendency of physical activity in elder period was determined by 24 week. There was no difference between two groups about physical activity. In conclusion, high-fat diet did not increase the appetite nor decrease the activity of the rats, but it gave weight easily to rats regardless the physical activity.
