What should I know about kein sattigungsgefuhl?

Lack of satiety (no feeling of fullness) can stem from hormonal imbalances (leptin, ghrelin), dietary patterns, psychological factors, or certain medical conditions. The provided context does not directly address satiety disorders. However, the FTO gene variant rs9939609 (A allele) is associated with a slightly higher BMI (0.3–0.5 kg/m² per copy) and has been linked to altered satiety perception. The effect is small and lifestyle dominates. Direct-to-consumer DNA tests claiming to explain poor satiety often overstate genetic influence. Neither microbiome tests nor IgE allergy panels (mentioned in context) are appropriate for evaluating satiety. A comprehensive medical workup—including hormone levels, eating behavior, and glucose regulation—is more informative than a standalone genetic test. Evidence for genetic contributions to satiety is moderate but insufficient for individual prediction or intervention.
