Evidence check: HLA-DQ2 in the context of Abnehmen

HLA-DQ2 is a genetic risk marker for celiac disease, not a weight loss gene. The link to weight loss is indirect: undiagnosed celiac can cause malabsorption and weight changes, but most HLA-DQ2 carriers never develop celiac. DNA testing for HLA-DQ2 is not validated for weight management. Evidence for a direct role in weight loss is lacking. MyBody-X tests can indicate risk but are not diagnostic. For suspected celiac, serology and biopsy are required. The evidence is clear: HLA-DQ2 is a risk factor for celiac, not a tool for weight loss. Be cautious of marketing claims suggesting otherwise.
