  • Fasting blood sugar measurement: Insulin secretion occurs more in fasting conditions. If you fast for 8 hours, insulin secretion decreases and blood sugar levels stabilize. This minimizes insulin action and allows accurate measurement of blood sugar concentration. 
  • Measuring blood sugar after a meal: Insulin regulates blood sugar levels and is used as energy to transport glucose into cells. The reason for measuring 2 hours after a meal is that after about 2 hours, carbohydrates are digested and blood sugar concentration reaches its highest level. Afterwards, insulin is secreted to control blood sugar levels. Therefore, if you measure after 2 hours, you can measure the blood sugar response and the effect of insulin action. 
  • Glycated hemoglobin: An indicator that represents the average level of glucose concentration in the blood. It is generally expressed as a percentage, with lower numbers indicating better blood sugar control, and higher numbers indicating worse blood sugar control.



Fasting blood sugar, often referred to as fasting glucose, is a crucial indicator of your overall health, especially in the context of metabolic wellness. This blog post will delve into the intricate details of fasting blood sugar, covering aspects such as its definition, the causes of high fasting blood sugar, associated symptoms, methods to lower fasting blood sugar, recommended foods for fasting, foods that should be avoided on an empty stomach, management techniques, and preventive measures. So, let’s embark on this informative journey to better understand and manage your fasting blood sugar levels.




1. Understanding Fasting Blood Sugar

Fasting blood sugar, also known as fasting glucose, is a measure of the amount of sugar (glucose) present in your bloodstream after an overnight fast. It is typically measured in milligrams per deciliter (mg/dL) and serves as a critical parameter in diagnosing and managing various metabolic conditions, including diabetes. Maintaining a normal fasting blood sugar level is essential for overall health.


2. Normal Fasting Blood Sugar Level

The normal fasting blood sugar level typically falls in the range of 70 to 100 mg/dL. This range indicates that your body is efficiently managing glucose levels during the fasting state. Deviations from this range can signal underlying health issues.


3. Causes of High Fasting Blood Sugar

Elevated fasting blood sugar levels can be attributed to several factors:


  • Insulin Resistance: This condition occurs when your body’s cells become less responsive to insulin, making it harder for glucose to enter cells.
  • Poor Diet: A diet high in refined sugars and carbohydrates can lead to spikes in blood sugar levels.
  • Stress: Chronic stress can elevate blood sugar levels as stress hormones interfere with insulin’s action.
  • Medications: Certain medications, such as corticosteroids, can raise fasting blood sugar levels.
  • Hormonal Changes: Hormonal imbalances, such as those seen in polycystic ovary syndrome (PCOS), can affect fasting blood sugar.
    It’s essential to identify and address the underlying cause of high fasting blood sugar to effectively manage it.


4. Symptoms of High Fasting Blood Sugar

High fasting blood sugar may manifest with symptoms like:

  • Increased Thirst: Elevated blood sugar levels can cause excessive thirst.
  • Frequent Urination: You may need to urinate more frequently.
  • Fatigue: High blood sugar can lead to fatigue and low energy levels.
  • Blurry Vision: Changes in blood sugar levels can affect your eyesight.
  • Unexplained Weight Loss: In some cases, high fasting blood sugar can lead to unintentional weight loss.


5. How to Lower Fasting Blood Sugar

Lowering fasting blood sugar involves lifestyle changes and, in some cases, medication. Here are some strategies:


  • Diet Modification: Focus on a balanced diet rich in whole grains, lean proteins, and vegetables. Limit sugar and refined carbs.
  • Regular Exercise: Engage in regular physical activity, including fasting cardio and strength training, which can improve insulin sensitivity.
  • Medication: Your healthcare provider may prescribe medications like metformin to manage blood sugar.
  • Stress Management: Incorporate stress-reduction techniques like mindfulness and relaxation exercises.
  • Adequate Sleep: Ensure you get enough rest, as poor sleep can affect blood sugar levels.


6. Foods That Are Good for Fasting Blood Sugar

Maintaining stable blood sugar levels begins with your diet. Incorporate these foods into your meals:

  • Fiber-Rich Foods: Whole grains, legumes, and vegetables can help stabilize blood sugar.
  • Lean Proteins: Chicken, turkey, fish, and tofu are excellent protein sources.
  • Healthy Fats: Avocado, nuts, and olive oil can aid in blood sugar control.
  • Leafy Greens: Spinach, kale, and collard greens are packed with nutrients.


7. Foods That Should Not Be Eaten on an Empty Stomach

Certain foods can irritate an empty stomach, leading to discomfort and potential digestive issues. Avoid:


  • Spicy Foods: Spices can irritate the stomach lining.
  • Citrus Fruits: The acidity can lead to heartburn.
  • Carbonated Drinks: These can cause bloating and gas.
  • Caffeine: Coffee and tea on an empty stomach can trigger acid production.


8. Management Methods for High Fasting Blood Sugar

Managing high fasting blood sugar involves a multi-faceted approach:


  • Regular Monitoring: Keep track of your blood sugar levels to assess progress.
  • Medication Compliance: If prescribed, take medications as directed.
  • Dietary Choices: Maintain a consistent and balanced diet.
  • Exercise Routine: Stick to a regular exercise regimen to improve insulin sensitivity.
  • Stress Reduction: Manage stress through relaxation techniques.


9. Prevention Methods for High Fasting Blood Sugar

Preventing high fasting blood sugar involves adopting healthy lifestyle choices:


  • Balanced Diet: Consume a diet rich in whole foods and low in added sugars.
  • Regular Exercise: Incorporate physical activity into your routine.
  • Weight Management: Maintain a healthy weight.
  • Stress Management: Practice stress-reduction techniques.
  • Regular Check-ups: Visit your healthcare provider for routine screenings.



In conclusion, understanding and managing fasting blood sugar levels is crucial for maintaining overall health and preventing metabolic disorders like diabetes. By making informed dietary choices, staying physically active, managing stress, and seeking medical guidance when necessary, you can achieve and maintain healthy fasting blood sugar levels. Remember that consistency and commitment to a healthy lifestyle play pivotal roles in this journey.
