C Changes in food intake of three groups. d Blood glucose response to a gastric glucose load at the 6th week. e Area under the curve of blood glucose at the 6th week. f Blood glucose response to a gastric glucose load at the 16th week. g Area under the curve of blood glucose at the 16th week. h Changes in fast blood glucose of three groups. Values are expressed as mean ± SD. n = 6. Compared with control group: ^#P < 0.05, ^##P < 0.01, ^### P < 0.001, ^#### P < 0.0001; Compared with IGT group, *P < 0.05, **P < 0.01, *** P < 0.001, **** P < 0.0001
