What should I know about sattigungsgefuhl?

Satiety feeling (Sattigungsgefuhl) is a complex process involving stomach distension, hormonal signals (e.g., leptin, ghrelin, GLP-1), and hypothalamic regulation. It determines meal termination and is key for energy balance. Direct-to-consumer DNA tests, such as those from MyBody-X, often analyze variants in genes like CLOCK, FTO, or MC4R that are associated with appetite regulation. However, effect sizes are small and easily overshadowed by lifestyle factors (fiber, protein intake, eating speed). Evidence comes mostly from observational studies; no large RCTs prove that DNA-based dietary advice improves satiety. A test may provide rough hints but cannot replace personalized nutrition counseling. Practical measures – high-protein meals, slow eating, adequate sleep, stress management – are far more impactful. The evidence level is best described as 'unclear' to 'marketing': lab certifications exist, but clinical utility for satiety is unproven.
