FC recovered the disturbed glucose metabolism and insulin resistance. iGTTs (a) were performed after starvation overnight after 20 weeks and AUC of iGTTs was calculated (a, the inserted figure). Serum insulin (b) after 20 weeks, body weight (c) from the 15th week to 20th week and food intake (d) in the last week were examined. Data are expressed as mean ± SEM (n = 6). * p < 0.05, ** p < 0.01 and *** p < 0.005. HFD, high fat diet; LFD, low fat diet; iGTTs, intra-peritoneal glucose tolerance tests; AUC, area under curve
