Is INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch useful for weight loss?

The INFINITY DNA-Test including a 28-day plan and recipe book is marketed for weight loss, but the scientific evidence is weak. DNA tests for weight management typically rely on common gene variants (e.g., FTO, PPARG) whose effects on metabolism or appetite are small and often not replicated in human trials. Personalized diet plans derived from such tests are usually based on general principles (calorie deficit, macronutrient balance) rather than validated genetic insights. The 28-day plan and recipe book may provide structure and motivation, but their specific link to the DNA test is unproven. Without accompanying blood biomarkers (e.g., nutrient deficiencies, glucose regulation), the test's utility for sustainable weight loss is limited. Evidence: marketing/mechanistic. Caveat: No randomized controlled trials exist for this product; individual results vary. Consult a doctor or dietitian before starting.
