| Adiposity index3 | 3.15 ± 0.17 | 3.06 ± 0.24 | 0.76 |
| Feed efficiency,4 mg body weight gained/total cumulative kcal consumed | 22.70 ± 0.72 | 22.70 ± 1.29 | 0.99 |
| OGTT (AUC), mg/dL × min | 15,700 ± 1200 | 17,200 ± 1100 | 0.38 |
| Plasma glucose, mg/dL | 138 ± 4.9 | 150 ± 9.5 | 0.07 |
| Plasma insulin, ng/mL | 0.60 ± 0.06 | 0.74 ± 0.12 | 0.27 |

1
Values are means ± SEMs; n = 15 in the control group, n = 14 in the HAMRS2 group. DCF, dichlorofluorescein; HAMRS2, high-amylose-maize resistant starch type 2; OGTT, oral-glucose-tolerance test.
2
Derived by using a 2-tailed Student’s t test. P ≤ 0.05 was considered significant.
3
Adiposity index is the sum of epididymal, retroperitoneal, and subcutaneous fat pads in grams. Plasma and tissue samples were collected from mice in the postabsorptive state after ∼4–8 h food deprivation in the morning.

To convert kcal to kJ, multiply by 4.184.
