Can IgG Unverträglichkeitstest help with Abnehmen?

The short answer: No, IgG food intolerance tests are not scientifically proven to aid weight loss. IgG antibodies indicate immune exposure, not intolerance or a causal link to weight gain. Major guidelines (e.g., EAACI) advise against IgG-based tests for diagnosis or dietary planning. The evidence is largely marketing-driven. For weight loss, focus on calorie deficit, macronutrient balance, physical activity, and sleep – factors with strong evidence. An IgG test may lead to unnecessary food restrictions and nutrient deficiencies without sustainable weight reduction. MyBody-X does not clearly differentiate between IgE (allergy) and IgG (unvalidated) in its product descriptions. Therefore, no recommendation for weight management.
