Can FADS1 help with Abnehmen?

FADS1 (fatty acid desaturase 1) is a key enzyme in the conversion of polyunsaturated fatty acids, especially omega-3 and omega-6. Certain variants (e.g., rs174547) have been associated in GWAS with altered fatty acid levels, but effect sizes are small and not directly linked to weight loss. No robust RCTs demonstrate that any FADS1 variant facilitates or hinders weight loss. The evidence is limited to associations with lipid traits (GWAS). Weight loss is primarily driven by calorie balance, diet, and exercise – a single gene has only marginal influence. Consumer DNA tests often overstate clinical relevance. Omega-3 supplementation may be generally beneficial, but not specifically due to a FADS1 SNP. Bottom line: FADS1 does not demonstrably help with weight loss; rely on evidence-based lifestyle interventions.
