HbA1c (glycated haemoglobin) is the most important long-term blood glucose marker for diabetes management. Understanding your result empowers you to track your keto progress meaningfully.
HbA1c reflects average blood glucose over the preceding 2–3 months by measuring the percentage of haemoglobin that has glucose attached to it. A single fasting glucose test captures one moment; HbA1c captures the trend.
Normal: under 42 mmol/mol (under 6.0%). Prediabetes: 42–47 mmol/mol (6.0–6.4%). Type 2 diabetes: 48 mmol/mol or above (6.5%+). Well-controlled diabetes target: under 48 mmol/mol.
Keto consistently reduces HbA1c within 3–6 months for those with elevated levels. Drops of 10–20 mmol/mol in the first 6 months are well-documented. Some individuals achieve normal HbA1c within 12 weeks.
Request HbA1c at baseline and every 3 months for the first year. Track the trend over time — each reduction is meaningful evidence of improving metabolic health. Support your results with our blood-sugar-stabilising keto recipes and low-GI keto snacks.
HbA1c is the single best objective measure of keto’s impact on metabolic health. Track it every 3 months and celebrate every reduction.
