What to watch with IgG and Abnehmen?

IgG (Immunoglobulin G) tests are often marketed to identify food sensitivities, with claims that eliminating reactive foods can promote weight loss. However, the scientific evidence is weak. IgG antibodies indicate prior exposure to food proteins, not necessarily intolerance or allergy. Many healthy individuals have elevated IgG to common foods without any symptoms. Studies show that IgG-guided elimination diets do not reliably lead to weight loss and may cause unnecessary dietary restrictions, nutrient deficiencies, and disordered eating. Reputable health organizations (e.g., DGE, AAAAI) advise against using IgG tests for weight management or general health. For weight loss, evidence-based strategies like caloric deficit, balanced nutrition, and physical activity are effective. IgG tests are not validated for this purpose and should be viewed as marketing rather than science. Evidence: marketing/unclear. Safety note: Avoid restrictive diets based solely on IgG results without medical supervision.
