The effects of high-fat plus high-fructose (HFHF) diet on gross appearance, overnight fasting serum glucose and insulin levels, and HOMA-IR in Lee-Sung pigs. Adult male pigs were fed with low-fat or HFHF diets for 12 months. a At the end of experiment, HFHF-diet-fed pigs were obese with larger waist sizes, and thicker abdominal fat, as well as backfat and facial fat compared to low-fat diet pigs. During the experimental period, body weight (b), overnight fasting serum glucose levels (c), fasting serum insulin levels (d) and HOMA-IR (e) were measured monthly. Data are expressed as means ± SEM (low-fat diet, n = 3; HFHF diet, n = 4). *p < 0.05, **p < 0.01
