Primary Outcome Measures:
  • Difference in the incremental area under the curve (iAUC) for peptide YY (PYY) after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.


Secondary Outcome Measures:
  • Difference in the iAUC for cholecystokinin (CCK) after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for ghrelin after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for glucagon-like peptide 1 (GLP-1) after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for glucose-dependent insulinotropic polypeptide (GIP) after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.


Other Outcome Measures:
  • Difference in the iAUC for glucose after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for insulin after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for C-peptide after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.

  • Difference in the iAUC for glucagon after food ingestion between high-protein and standard diet groups [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    Blood samples were drawn before the test meal (time 0) and at 30, 60, 90, 120, and 180 min after the test meal commenced.
