What role does Homocystein play in Abnehmen?

Homocysteine is a sulfur-containing amino acid produced during methionine metabolism. Elevated homocysteine is associated with oxidative stress, inflammation, and endothelial dysfunction—factors that may indirectly impair metabolism and fat oxidation. However, there is no strong evidence that homocysteine directly drives weight loss. Observational studies link high homocysteine to obesity, metabolic syndrome, and insulin resistance, but causality remains unclear. Lowering homocysteine via folate, B12, or betaine does not reliably produce weight loss. Thus, homocysteine's role in weight management is primarily as a biomarker of methylation status and cardiovascular risk, not as a direct weight-loss target. For effective weight loss, focus on energy balance, physical activity, and a nutrient-dense diet. Genetic testing for MTHFR variants (which affect homocysteine) is not clinically recommended for weight loss. Evidence grade: human-moderate (observational).
