Is IgE useful for Abnehmen?

IgE (Immunoglobulin E) is primarily involved in allergic reactions and has no direct, evidence-based role in weight loss. While IgG tests (like NutriCheck I) are often marketed for food intolerances, IgE is specific to immediate-type allergies (e.g., pollen, foods). Neither IgE nor IgG levels provide a reliable basis for weight reduction. Measuring IgE may help identify allergy-related symptoms that could indirectly affect eating behavior – for instance, in undiagnosed food allergies. However, its utility for structured weight loss is not scientifically supported. The evidence is weak and based on mechanistic reasoning, not clinical trials. Consumers should not rely on IgE values as a weight-loss tool; instead, calorie balance, exercise, and a balanced diet remain the most effective approaches per current evidence. Safety note: IgE testing should only be performed when allergy is suspected and under medical supervision.
