Glucose monitoring tracks the weather, not the climate

Isolated blood glucose readings often mislead because they capture transient spikes rather than long-term metabolic health. Researchers at Stanford followed 57 participants and observed that 80 percent experienced glucose spikes after consuming standard breakfasts, with many hitting prediabetic or diabetic ranges despite having normal blood tests (Victor). These spikes represent rainy afternoons in a climate that remains stable, as monitor data does not substitute for the A1c test which reflects multi-month control. A larger study of 972 adults confirmed that monitor readings correlate weakly with long-term markers in healthy populations.

Dr. Boz proposes a more granular approach by tracking the ratio of fasting glucose to blood ketones, which measures how effectively the liver produces ketones (Dr. Boz). A glucose reading of 90 mg/dL paired with 0.3 mmol/L of ketones yields a ratio of 300, while the same glucose with 1.0 mmol/L of ketones results in a ratio of 90. This metric reveals internal insulin function that a single glucose number hides. Aiming for a ratio below 100 on two mornings a week provides a target for metabolic tuning. You can refine this by recording daily carbohydrate intake and sleep quality to identify patterns over six weeks.

Establish your baseline Dr. Boz Ratio by measuring fasting glucose and ketones for one week.

Measure both values each morning before breakfast and divide glucose (mg/dL) by blood BHB (mmol/L).

You need

  • Blood glucose and ketone meter
  • Test strips
  • Logbook or spreadsheet

Steps

  1. Prick finger after waking but before consuming any food or drink.
  2. Record the glucose value in mg/dL.
  3. Record the blood ketone value in mmol/L.
  4. Divide the glucose value by the ketone value to calculate your ratio.
  5. Note the previous day's total carbohydrate intake alongside your ratio.
