Can tTG IgA help with weight loss?

tTG IgA (tissue transglutaminase antibodies) is a well-established biomarker for celiac disease, not for weight loss. In untreated celiac disease, malabsorption may lead to weight loss, but the test is for diagnosis, not weight management. Without celiac or gluten sensitivity, tTG IgA provides no actionable information for weight loss. The provided context contains no evidence that this marker aids weight loss. A positive test requires medical follow-up; a gluten-free diet without medical indication is not evidence-based for weight reduction. Evidence: unclear.
