Evidence check: Homocystein in the context of Abnehmen

Homocysteine is a sulfur-containing amino acid derivative considered a risk marker for cardiovascular disease. In the context of weight loss, evidence suggests that obesity and poor diet are associated with elevated homocysteine levels. Weight loss—especially through a balanced diet rich in folate, vitamin B12, and B6—can lower homocysteine. However, homocysteine is not a direct predictor of weight loss; it rather reflects overall health and nutrient status. DNA tests for variants like MTHFR are often marketed, but evidence for personalized weight loss based on homocysteine is weak. MyBody-X products (e.g., Cardio Risk Check) may measure homocysteine as part of a cardiovascular risk panel, providing orientation but not specific diet advice for weight loss. Conclusion: Homocysteine is a useful health marker but not a tool for diet optimization. Evidence: human-moderate (observational studies, mechanistic links).
