Evidence check: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch in the context of weight loss

The 'INFINITY DNA-Test' with a 28-day plan and recipe book is marketed as a personalized weight-loss solution. However, the scientific foundation is weak: DNA nutrition tests analyze genetic variants with mostly small effect sizes (e.g., FTO, MC4R), indicating tendencies rather than strict dietary rules. The included 28-day plan and recipe book are likely generic healthy-eating recommendations, not truly tailored to individual genotypes. Clinical trials demonstrating significant weight loss from DNA-based diets are largely lacking. The evidence is mixed: some gene–diet interactions are mechanistically plausible, but translating them into real-world outcomes yields little measurable advantage over a balanced diet without genetic testing. Additionally, results are often less accurate for non-European populations. The test is not a medical device and should not be used for diagnosis or treatment. For weight loss, a calorie-controlled, nutrient-dense diet and regular exercise remain far more effective—with or without a DNA test.
