Blood Biomarkers

Blood ketone measurement is more accurate than urine strips for assessing the depth of ketosis. Urine ketone strips become unreliable after one to two weeks of a ketogenic diet because the body adapts and utilizes rather than excretes ketones. HbA1c measures average blood glucose concentration over the preceding three months by assessing glycated hemoglobin percentage. HbA1c is one of the most important markers for detecting prediabetes, insulin resistance, and type 2 diabetes before symptoms appear. Postprandial blood glucose response is a key indicator of insulin sensitivity and metabolic flexibility. Checking blood sugar after specific meals can identify problem foods before they cause long-term damage.
