Myths vs facts: HbA1c and Abnehmen

HbA1c (glycated hemoglobin) is a long-term blood sugar marker reflecting average glucose over 2–3 months. A common myth is that HbA1c directly measures weight loss. In reality, HbA1c decreases only when blood sugar control improves through diet, exercise, or medication – which can accompany weight loss but is not guaranteed. Another myth: HbA1c is equally reliable for everyone. Fact: HbA1c can be skewed by anemia, hemoglobin variants, kidney disease, or certain medications. For weight loss, HbA1c is an indirect marker: a drop suggests better metabolic health, but not necessarily fat loss. Those aiming to lose weight should also assess body fat, fasting glucose, and insulin resistance markers (e.g., HOMA-IR). The evidence is clinically established (practice), but interpretation requires context. Consumer tests offering HbA1c alone provide only part of the picture.
