Myths vs facts: Testosteron and Abnehmen

Myths vs. facts: Testosterone and weight loss – a topic often exaggerated by marketing. Fact: Testosterone influences muscle mass and fat distribution, but a direct causal effect on weight loss is not clearly proven. Studies show that men with low testosterone are more likely to be overweight, but supplementation does not automatically lead to weight loss – especially without lifestyle changes. Many 'testosterone boosters' from DNA tests or supplements are based on weak evidence (mostly mechanistic or marketing). Genetics (e.g., SHBG gene variants) play a role, but the effect is small. Important: Testosterone preparations are prescription-only and can have side effects. Consumer DNA tests do not provide reliable information about testosterone levels or the ideal diet. Bottom line: Weight loss requires a calorie deficit, exercise, and sleep – not just hormone optimization. The evidence is mixed; individual factors dominate.
