How are INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch and weight loss related?

The 'INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch' is a commercial product combining a DNA test with a 28-day diet and recipe plan. Based on the provided context, there is no direct evidence linking this specific test to weight loss. The knowledge entries on FTO, BDNF, and other genes show that single variants have only tiny effects on BMI (e.g., FTO rs9939609: ~1–2 kg) and are easily overshadowed by lifestyle. A 28-day plan may produce short-term weight loss, but this is likely due to calorie restriction and behavior change rather than genetic insights. Evidence for personalized DNA-based diets is weak; most claims are marketing-driven. Consumers should be aware that such tests cannot guarantee results and that sustainable weight loss relies on balanced nutrition, exercise, and habit change.
