IgG antibodies against foods are often marketed as indicators of 'delayed food intolerances', with the promise that eliminating those foods will lead to weight loss. However, the evidence is clear: IgG tests are not validated for diagnosing food allergies or intolerances (PMC5004213). They frequently produce false positives and are not recommended by allergy experts. While some studies report subjective symptom improvement with IgG-guided elimination diets, no robust, reproducible effect on body weight has been demonstrated. Any weight loss observed is likely due to the general calorie restriction from the elimination diet rather than the IgG results themselves. Moreover, unnecessary dietary restrictions can lead to nutrient deficiencies. For weight loss, evidence-based approaches such as caloric deficit, macronutrient balance, and physical activity are far more reliable. Notably, the MyBody-X Body-Balance Check measures hsCRP as an inflammation marker, which is more relevant to weight management, but IgG is not part of that panel.","area":"gesundheit","canonical_id":"gesundheit:canonical-983ba4044245615bd6f9b24d","id":"public-c23c3ac2123ad03fa025295a","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: IgG in the context of weight loss","score":25.56821878,"snippet":"Using IgG tests in the context of weight loss lacks scientific support.
