Ein häufiger Mythos besagt, dass Gewichtsverlust allein den HbA1c-Wert senkt – das stimmt nur indirekt. Tatsächlich verbessert eine nachhaltige Gewichtsabnahme die Insulinsensitivität, was zu niedrigeren Blutzuckerwerten und damit zu einem sinkenden HbA1c führen kann. Allerdings ist der Effekt nicht linear: Schon eine moderate Reduktion von 5–10 % des Körpergewichts kann bei Prädiabetes oder Typ-2-Diabetes klinisch relevante HbA1c-Senkungen bewirken. Ein weiterer Mythos ist, dass HbA1c direkt den Gewichtsverlust misst – das ist falsch. HbA1c ist kein Gewichtsmarker, sondern ein Stoffwechselparameter. Crash-Diäten oder extreme Kalorienrestriktion können den HbA1c kurzfristig senken, aber oft auf Kosten von Muskelmasse und Nährstoffversorgung. Die evidenzbasierte Empfehlung lautet: Kombination aus moderater Kalorienreduktion, regelmäßiger Bewegung und ausreichend Schlaf. Genetische Tests auf HbA1c-Varianten (z. B. rs713598) haben keine klinische Relevanz für die Gewichtsabnahme. Wichtig: HbA1c-Werte unter 5,7 % gelten als normal; Werte zwischen 5,7 und 6,4 % deuten auf Prädiabetes hin.

However, a direct causal effect on weight loss is not established.
