The maximum increases in insulin concentration and iAUC for serum insulin after the CAC meal were 24% (P = 0.24) and 18% (P = 0.52) lower, respec- tively, than after the CAB meal. The maximum increases in C-peptide concentration and iAUC for C-peptide were not sig- nificantly different between the 3 meals (Table 2). There was no significant difference (P = 0.1) in EE (Figure 4) or in the respi- ratory quotient between the 3 meals (Table 2).
We hypothesized that there might be a difference in the mea- sured variables between those with different BMIs. To confirm this hypothesis, general linear modeling and postestimation het- erogeneity testing between meals was conducted for the mea- sured variables after the whole group was separated into 2 groups
