Can Nährstoffcheck help with Abnehmen?

A nutrient check (e.g., blood test for vitamins and minerals) can indirectly support weight loss by identifying deficiencies that may impair metabolism or energy levels, such as low vitamin D or B12. However, it is not a direct weight-loss tool. The provided context indicates that genetic risk variants for obesity have very small effect sizes (~0.3 BMI per allele). A nutrient test does not address calorie balance or provide a diet strategy. It can serve as supportive information but does not replace a calorie deficit and physical activity. The evidence for direct weight loss from nutrient testing is weak; it rests on mechanistic reasoning and practice, not on randomized trials. Caveat: test results are only one piece of the puzzle – a holistic approach (physician, dietitian) is essential.
