Myths vs facts: AMH and weight loss

AMH (Anti-Müllerian Hormone) is primarily a marker of ovarian reserve, not a direct indicator of weight loss. Some studies have explored the relationship between weight changes and AMH levels, but results are mixed and effect sizes are generally small. A few observational studies suggest that significant weight loss in overweight women may be associated with a slight increase in AMH, while others find no association. Importantly, AMH is not a metabolic or fat-burning biomarker. Consumer tests measuring AMH are intended for fertility assessment, not for guiding weight loss. The evidence is weak and based on observational data. An AMH level alone cannot predict or monitor weight loss success. For weight management, established parameters like calorie balance, physical activity, and metabolic markers (e.g., fasting glucose, HbA1c) are more relevant. The idea that AMH can predict or drive weight loss is a myth lacking robust scientific support.
