What role does Selen play in Abnehmen?

Selenium is an essential trace mineral critical for selenoproteins, including iodothyronine deiodinases (DIO1, DIO2) that convert thyroid hormones (T4 to active T3), thereby influencing basal metabolic rate. Selenium deficiency can impair thyroid function and potentially reduce energy expenditure, which might hinder weight loss. However, direct evidence for selenium promoting weight loss in humans is weak and inconsistent. Some observational studies suggest an inverse association between selenium status and body fat, while others show no effect or even a positive link at high levels. Importantly, excessive selenium intake (above the recommended dietary allowance of ~55–70 µg/day) can lead to selenosis and has been associated with increased type 2 diabetes risk. Therefore, supplementation should only be considered after blood testing. MyBody-X tests do not directly assess selenium or its role in weight loss. Overall, the evidence is unclear – selenium is not a standalone weight-loss agent.
