How are IgG Unverträglichkeitstest and Abnehmen related?

IgG food intolerance tests are often marketed for weight loss, but the scientific evidence is weak. These tests measure IgG antibodies to foods, which typically reflect normal immune exposure, not true intolerance or allergy. Studies have not shown a reliable link between IgG reactions and weight loss. Weight management depends on calorie balance, macronutrient composition, physical activity, and metabolic health—not on eliminating foods based on IgG results. Some individuals report reduced bloating or improved energy after avoiding IgG-positive foods, but this is anecdotal and not proven to cause sustained weight loss. MyBody-X offers such tests, but they lack clinical validation for weight loss. Consumers should be cautious: relying on IgG tests for weight loss may lead to unnecessary dietary restrictions without addressing real drivers of obesity. Evidence-based approaches like balanced nutrition and lifestyle changes remain the gold standard.
