What role does Leaky Gut Test play in weight loss?

The role of a Leaky Gut Test in weight loss is not supported by strong scientific evidence. These tests measure markers like zonulin in stool or blood, which are claimed to indicate increased intestinal permeability. The theory suggests that a leaky gut promotes inflammation, which may contribute to weight gain. However, robust clinical studies demonstrating a causal link or a benefit of the test for weight loss are lacking. The evidence is limited to mechanistic hypotheses and marketing claims. Many labs offer such tests without standardized reference ranges or validated clinical guidelines. A positive result should not lead to extreme diets or expensive supplements. A more evidence-based approach focuses on overall diet quality, gut health, and lifestyle factors. If you suspect gut issues, consult a gastroenterologist before making decisions based on this test.
