Myths vs facts: IgE Allergietest and weight loss

The idea that an IgE allergy test can help with weight loss is a myth. IgE tests (e.g., for food allergens) are designed to diagnose immediate-type allergies, not to promote weight loss. There is no scientific evidence that avoiding IgE-positive foods leads to significant or sustainable weight reduction. Weight loss is primarily achieved through a calorie deficit, dietary changes, and physical activity. While undiagnosed allergies can cause symptoms like bloating or fatigue, resolving these may improve well-being but does not directly cause weight loss. Commercial providers often conflate allergy tests with 'intolerance tests' and market them as weight-loss aids – this is misleading. An IgE test should only be used when an actual allergy is suspected, not for diet planning. Evidence: marketing/unclear. Sources: none from the provided context.
