Evidence check: Body-Balance Check | Testosteron-Test in the context of Abnehmen

The Body-Balance Check including a testosterone test from MyBody-X is marketed as a tool for weight loss. The scientific evidence is nuanced. Testosterone plays a role in fat metabolism and muscle building – low levels in men are associated with higher body fat and reduced muscle mass. However, a testosterone test is not an established weight loss tool. Most studies show that testosterone replacement therapy only leads to modest fat reduction in men with clinically confirmed hypogonadism (with symptoms), not in healthy men with normal levels. Evidence in women is even weaker. Moreover, this is a home test – results are not diagnostic and require medical follow-up. Without a clinical indication, there is a risk of misinterpretation or unnecessary supplementation. For sustainable weight loss, calorie deficit, exercise, and behavioral change remain the evidence-based pillars. The test may provide supplementary insight but does not replace medical evaluation. Evidence grade: human-moderate (studies exist on testosterone and body composition, but not specifically for home tests in weight loss).
