Is MY FOODBOOK useful for weight loss?

The MY FOODBOOK DNA test (also sold as INFINITY DNA-Test) provides genetic insights into metabolic and sport types along with dietary recommendations. The evidence for direct weight loss is moderate: individual gene variants have small effects, and findings are based on observational studies, not randomized controlled trials. The test can serve as a motivational tool and orientation for a healthier lifestyle, but it does not replace medical or nutritional counseling. The product description includes marketing language; weight loss is not guaranteed. Caveat: For serious weight issues or metabolic conditions, consult a physician.
