What role does Leaky Gut Test play in Abnehmen?

The role of a Leaky Gut Test in weight loss cannot be determined from the provided context, which contains no information about such a test or its link to weight management. Leaky gut (increased intestinal permeability) is a controversial concept, often associated with vague symptoms like bloating or fatigue. A direct causal role in weight loss is not scientifically established. Many commercial tests measure markers like zonulin, but their clinical utility is limited. Evidence for using these tests to guide weight loss is weak and largely based on marketing claims. Sustainable weight loss depends on caloric balance, diet quality, and physical activity—not on measuring gut permeability. Without specific study data or guidelines in the context, the evidence level is best described as 'marketing' or 'unclear'.
