There was a significant high correlation of ghrelin ( r = 0.411, p < 0.001) and GLP‐1 ( r = 0.576), p < 0.001) and a nonsignificant trend correlation with peptide YY ( r = 0.218, p = 0.081) in the FBF group; a nonsignificant trend correlation of ghrelin ( r = 0.254, p = 0.064); a significant high correlation of GLP‐1 in the PBF group (0.378, p = 0.006); and a significant high correlation of GLP‐1 ( r = 0.407, p = 0.029), but no correlation with ghrelin, leptin, and peptide YY in the HMS group. 4.
