Characteristic	Standard diet group	High-fat diet group	P value
Initial body weight, g	218.13±16.93	223.73±13.68	0.187
Body weight, g	286.83±14.91	349.56±22.72	<0.01
Heart weight, g	0.81±0.12	0.84±0.07	0.234
Weight of epicardial fat, g	0.37±0.29	0.71±0.15	<0.05
Weight of appendage, g	0.03±0.01	0.21±0.44	0.144
Weight of perigonadal fat, g	6.96±3.02	13.15±6.38	<0.05

Values are expressed as mean±SD. Initial body weight (g) means body weight before starting a standard diet or a high-fat diet. Student t test was used to compare the parameters of the standard diet and high-fat diet groups.
