Myths vs facts: FADS1 and Abnehmen

FADS1 encodes enzymes involved in polyunsaturated fatty acid metabolism (omega-3/omega-6). Marketing often claims that variants 'slow metabolism' or hinder weight loss. Scientific evidence is moderate: GWAS studies link FADS1 variants to altered blood lipid profiles, but the effect on body weight is small and overshadowed by diet and lifestyle. A direct 'fat-burning gene' test is misleading. Clinical relevance for weight loss is limited; personalized nutrition based solely on this gene is not evidence-based. Focus on calorie balance, macronutrient distribution, and physical activity instead. Beware of exaggerated promises from DNA-based diets.
