Evidence check: Magnesium in the context of Abnehmen

Magnesium is often mentioned in the context of weight loss, but the evidence is limited. Magnesium is an essential mineral involved in over 300 enzymatic reactions, including energy metabolism, glucose homeostasis, and insulin sensitivity. Some observational studies show an association between low magnesium levels and higher BMI or insulin resistance. Small intervention trials suggest that magnesium supplementation in individuals with deficiency or overweight may lead to modest improvements in fasting blood sugar and waist circumference. However, large-scale randomized controlled trials demonstrating a direct causal effect on weight loss are lacking. The effects are small and not comparable to those of calorie restriction or exercise. Genetic testing can identify variants (e.g., in TRPM6) that influence magnesium status, but clinical relevance for weight loss is unclear. Conclusion: Magnesium can be part of a healthy diet, but there is no strong evidence that it alone significantly aids weight loss. Supplementation may be considered in cases of deficiency or specific risk groups, but not as a primary weight loss strategy.
