What role does Folsäure play in Abnehmen?

Folic acid (vitamin B9) is essential for one-carbon metabolism and DNA methylation. Some studies suggest a link between folate status and body weight, but evidence for a direct weight-loss effect is weak. MTHFR variants (e.g., rs1801133) can impair folate utilization, yet their impact on weight loss is unclear. A deficiency may slow metabolism, but supplementation alone does not cause weight loss. For overweight individuals, a holistic dietary change with adequate folate from natural sources (leafy greens, legumes) is more appropriate. The evidence is mixed; marketing claims should be viewed critically.
