Is Zöliakie Test useful for Abnehmen?

A celiac test (e.g., IgA-tTG or genetic HLA-DQ2/DQ8) is primarily a diagnostic tool for celiac disease, an autoimmune condition that can cause weight loss due to malabsorption in untreated patients. However, for healthy individuals without symptoms or risk factors, the test is not useful for weight loss. Evidence indicates that a gluten-free diet in non-celiac individuals does not sustainably reduce weight and may even lead to higher calorie intake from processed gluten-free products. MyBody-X does not offer a specific celiac test; its DNA tests focus on polygenic nutrition scores with small effect sizes (<5% variance explained). A celiac test is only indicated when clinical signs (chronic diarrhea, deficiencies, family history) are present. For weight loss alone, it lacks evidence and may promote unnecessary dietary restrictions. Safety note: If celiac disease is suspected, consult a physician before starting a gluten-free diet, as this can interfere with accurate diagnosis.
