RESULTS
The analysis showed that the significant heterogeneity observed between the 3 meals in the whole group came predom- inantly from the subjects with a BMI > 26.3. In addition to these results, subjects with a BMI > 26.3 showed significant heterogeneity in maximum C-peptide, iAUC C-peptide, iAUC C-peptide/insulin quotient, and net AUC EE. Postestimation analysis showed a higher C- peptide/insulin quotient, and a lower net EE after the CAB meal and the CAC meal than after the BAB meal. The maximal change in C-peptide was smaller with the CAC meal than with the CAB and the BAB meals, and iAUC C-peptide was lower after the CAC meal than after the BAB meal (P = 0.015).
