Let's Talk Sugar: Master Your Fasting Glucose Numbers 

Have you noticed a daily pattern in your blood glucose readings? They may be higher during one part of the day and lower during another. This doesn’t mean anything is wrong, but it results from many factors that affect your blood sugar level. 

Look for improvement over time, not from one reading to the next. Consider how long it may have taken for your body to develop insulin resistance and lose control over blood glucose levels. Improvement can also take time, though you may see other health problems improve even while your blood glucose is not yet normal. 

Blood Glucose Reading Interpretation

  • 70-99 mg/dL: Your blood glucose is in the normal fasting range.
  • 100-125 mg/dL: This range indicates insulin resistance and abnormal fasting blood sugar.
  • 126 mg/dL or more: This range indicates diabetes and poor glucose control.

Steps You Can Take to Improve Your Blood Glucose Level

You can improve your blood glucose levels and, therefore, your hemoglobin A1C and the long-term effects of high blood sugar by gathering clues.

‍

  • Double-check your carbohydrate consumption. Make particularly sure you’re not eating some carbs late in the day.
  • Be sure you’re following the amount of daily protein Revero recommends and distributing it through your daily meals.
  • Don’t eat late in the evening if your blood sugar is high in the morning. Instead, try to eat dinner a little earlier.
  • Make sure you drink sufficient water and get 5 grams of sodium per day.
  • Don’t skimp on sleep, but aim for six to eight hours every night.
