How are MY FOODBOOK and Abnehmen related?

MY FOODBOOK is a personalized nutrition program by MyBody-X based on DNA and/or microbiome analysis. The concept: by identifying genetic variants (e.g., in fat metabolism, lactose intolerance) and gut bacteria composition, tailored dietary recommendations are provided to facilitate weight loss (Abnehmen). The link between MY FOODBOOK and weight loss lies in the promise that a diet aligned with individual biology is more effective than generic diets. However, the evidence is weak: most SNP effects on body weight are small, and microbiome profiles fluctuate. No randomized controlled trials show that MY FOODBOOK leads to significantly greater weight loss than a balanced, calorie-restricted diet. Moreover, the tests are not diagnostic and cannot rule out medical causes of obesity. A critical point: results are meant as guidance, not a substitute for medical advice. Those aiming to lose weight should still focus on proven factors like calorie balance, exercise, and sleep. MY FOODBOOK may provide motivation, but the scientific basis is currently more marketing-driven than evidence-strong.
