Current clinical-metabolomic biomarkers (including BCAA and lipid profiles) cannot predict individual changes in insulin sensitivity following lifestyle interventions, despite their ability to correlate with baseline insulin levels.

Do not rely on current commercial metabolomic tests (like BCAA or detailed lipid panels) to predict whether you will lose weight or improve insulin sensitivity through exercise. These tests may tell you your current risk status, but they cannot tell you how your body will respond to a specific lifestyle change.

Thus, we demonstrate that... none of the clinical-metabolomic biomarkers, validated in cross-sectional data, are suitable for monitoring longitudinally changes in IR status.
