Can IgG help with Abnehmen?

The idea that IgG antibodies (immunoglobulin G) can directly help with weight loss is not supported by strong scientific evidence. IgG tests are often marketed for food sensitivities, but their role in weight management is unclear. Some small studies suggest that an elimination diet based on IgG reactivity may lead to short-term weight loss, but this is likely due to reduced calorie intake or removal of certain foods rather than a specific IgG mechanism. Major medical organizations (e.g., DGE, EAACI) do not recommend IgG-based diets for weight loss, citing lack of standardization, high false-positive rates, and no proven causal link. IgG is a marker of immune exposure, not intolerance or metabolic function. For sustainable weight loss, evidence-based approaches like calorie deficit, balanced nutrition, and physical activity are far more effective. Relying on IgG testing for weight loss is not advisable and may lead to unnecessary dietary restrictions without clinical benefit.
