Evidence check: Testosteron in the context of weight loss

Testosterone plays a role in fat metabolism and muscle building, but its direct effect on weight loss is complex and individual. In men with clinically confirmed hypogonadism, testosterone replacement therapy can reduce body fat percentage and improve body composition. However, evidence for weight loss in men with normal testosterone levels is weak. Studies indicate that testosterone alone, without lifestyle changes, does not produce significant weight loss. Moreover, high doses or misuse can lead to serious side effects such as cardiovascular issues, liver toxicity, and hormonal imbalances. For women, the evidence is even more limited; testosterone is not recommended for weight loss. In summary, testosterone is not a magic bullet for weight loss. A deficiency should be evaluated medically, but supplementation without indication is risky and not evidence-based. MyBody-X tests can measure hormone levels, but interpretation and therapy require medical supervision.
