MY FOODBOOK is a personalized nutrition test based on DNA analysis. Regarding fatigue, there is no robust scientific evidence that this test can identify specific causes or provide effective treatment. Fatigue has many potential triggers – from sleep deprivation and stress to medical conditions like anemia or thyroid disorders. The genetic variants analyzed by MY FOODBOOK (e.g., FTO, MTHFR) typically have small effect sizes and do not allow precise conclusions about fatigue. The evidence for such tests is largely marketing-driven; benefit claims are often exaggerated. A food diary or medical evaluation is far more useful for persistent fatigue than a genetic test. Caveat: The test cannot diagnose or treat any condition.
