Is Zöliakie Test useful for weight loss?

A celiac test is primarily a diagnostic tool for the autoimmune condition celiac disease, not for weight loss. In undiagnosed celiac disease, a gluten-free diet can lead to weight normalization – by improving malabsorption and inflammation. However, this is not a general weight-loss trick. Most direct-to-consumer tests screen for HLA-DQ2/DQ8 gene variants, which are necessary but not sufficient for celiac disease. A positive genetic test does not mean you have celiac; only a duodenal biopsy confirms diagnosis. For weight management without celiac symptoms, the test is not appropriate. Evidence for weight loss from a gluten-free diet in non-celiac individuals is weak and often overhyped by marketing. Bottom line: The test is useful if celiac is suspected, but not as a weight-loss tool. Consult a doctor before changing your diet.
