This is the third installment in a series of articles exploring lab tests for people following low-carb diets, and how this way of eating requires a slightly different perspective for interpreting the results compared to results from people eating more carbohydrates.
In part 1, we covered tests for blood sugar (fasting glucose, hemoglobin A1c, and fructosamine). In part 2, we explored fasting insulin, the most important test most doctors aren’t ordering. Taken together, these explain why fasting glucose and hemoglobin A1c in the “normal” ranges don’t always mean someone’s in the clear with regard to insulin sensitivity and healthy glucoregulation. (Crash course: for many people, dangerously high insulin is the only thing keeping glucose levels in a healthy range.)
Throughout this series, we’re emphasizing that health cannot be determined by any single measurement in isolation. It’s a mosaic, made up of many individual parts that are best assessed as a whole. With this in mind, let’s dig a little deeper into the relationship between glucose and insulin. (more…)
