What role does MY FOODBOOK play in weight loss?

MY FOODBOOK is a direct-to-consumer test that claims to provide personalized nutrition advice based on DNA, biomarkers, or lifestyle inputs. Its role in weight loss is not well-supported by independent clinical evidence. Most such tests rely on small-effect genetic variants or mechanistic associations, not robust randomized trials. Marketing often overstates the practical impact. While they may increase user engagement or awareness, there is no proof that they outperform standard dietary counseling for sustained weight loss. Individual results vary widely, and factors like adherence, overall diet quality, and physical activity dominate. The evidence level is best described as 'preliminary' or 'marketing-driven.' Caveat: This is not medical advice; consult a healthcare provider for weight management.
