Is IgG useful for Abnehmen?

The question of whether IgG testing is useful for weight loss is controversial. The provided context contains no information about IgG or its link to weight loss. IgG tests are often marketed to identify food sensitivities, but the scientific evidence for their utility in weight reduction is weak. Studies indicate that IgG antibodies to foods often reflect normal immune exposure rather than clinically relevant intolerance. Elimination diets based on IgG tests may lead to short-term weight loss, but this is typically due to reduced calorie intake, not a specific IgG effect. Moreover, there is a risk of unnecessary dietary restrictions and nutrient deficiencies. For evidence-based weight loss, caloric balance, a balanced diet, and exercise are key. IgG tests should not be used as the sole basis for dietary decisions. Consult a doctor or dietitian.
