How are Folsäure and Abnehmen related?

The direct link between folic acid (vitamin B9) and weight loss is scientifically weak. Folic acid is essential for one-carbon metabolism, DNA synthesis, and homocysteine regulation. Some observational studies suggest that low folate status may be associated with higher obesity risk and metabolic syndrome, possibly via epigenetic effects or altered lipid metabolism. However, robust intervention trials showing that folic acid supplementation causes weight loss are lacking. Genetic variants (e.g., in MTHFR) can affect folate metabolism, complicating the interpretation of DNA test results. A balanced diet rich in natural folate (leafy greens, legumes) is recommended, but targeted supplementation for weight loss is not evidence-based. Caution: high-dose folic acid can mask vitamin B12 deficiency. The evidence level is best described as 'mechanistic' or 'mixed'.
