Myths vs facts: Nährstoffcheck and Abnehmen

Myths vs. facts: Nutrient check and weight loss. A nutrient check (blood or DNA test) can identify deficiencies that may impair metabolism – e.g., vitamin D, iron, or B12. Fact: Correcting a genuine deficiency can improve energy and fat oxidation. Myth: A nutrient check alone does not cause weight loss; it is no substitute for a calorie deficit and physical activity. Many DTC tests lack clinical validation and offer generic advice. Evidence is mixed: supplementation helps when deficiency exists, but for healthy individuals without symptoms, the benefit is minimal. Caveat: Overemphasis on 'risk genes' (e.g., FTO) may lead to fatalism. A nutrient check can be a useful adjunct to personalized nutrition counseling, but not a standalone weight-loss solution.
