Managing one’s health often comes down to understanding the basics of our body’s responses to our lifestyle choices. One key aspect of health that affects everyone, from the young to the elderly, is blood sugar levels. 

Whether you sip a morning latte, enjoy a weekend dessert, or fuel up with a hearty meal, your body’s response to the sugars and carbohydrates you consume is critical to your overall well-being.

But what exactly is a “good” blood sugar response? Simply put, the body can efficiently manage and stabilize the sugar levels in your bloodstream after you eat or drink.

This process is crucial because it impacts not only energy and mood but also long-term health outcomes, including the risk of diabetes and heart disease.

What is blood sugar response?

Blood sugar response refers to how your body processes glucose after consuming food or drinking [1]. When you eat, carbohydrates break down into glucose, entering the bloodstream and causing your blood sugar levels to rise. 

The pancreas responds by releasing insulin, a hormone that helps cells absorb and use glucose for energy. A healthy blood sugar response involves a swift, efficient increase in blood sugar followed by a steady decline back to baseline. 

However, variations in this response can lead to issues like energy crashes or long-term health problems such as insulin resistance or diabetes. Understanding this process is crucial for managing dietary choices and maintaining overall health.

How do you measure blood sugar response?

Measuring and monitoring your blood sugar response is not just for those with diabetes; it’s a proactive step towards understanding your body and managing your health optimally.

Let’s discuss how blood sugar response is measured to help you effectively track and interpret your blood sugar levels.

Traditional methods

Traditional methods of monitoring blood sugar primarily involve blood glucose meters and hemoglobin A1c tests [2]. 

A blood glucose meter requires a small drop of blood [3], usually from the fingertip, and provides immediate readings of blood sugar levels at that moment. This helps us understand how different activities and foods impact blood sugar

The hemoglobin A1c test, on the other hand, offers a longer-term view by measuring the average blood sugar levels over the past two to three months. This test assesses the percentage of glycated hemoglobin proteins in the blood (coated with sugar).

New technologies

New technologies in blood sugar monitoring include continuous glucose monitors (CGMs) and epigenetic testing. 

CGMs provide real-time, continuous tracking of glucose levels via a sensor placed under the skin, giving users insights into glucose trends throughout the day [4]. This can help identify how lifestyle and dietary choices affect blood sugar levels. 

Additionally, genetic tests like the Longevity.Technology System Epigenetic & DNA Test offer a deeper understanding of how one’s genetic makeup influences glucose metabolism. 

This personalized approach allows individuals to tailor their diet and health strategies to optimize blood sugar control based on their unique genetic profile.

What is the safe range for blood sugar?

Understanding normal blood sugar levels is crucial for maintaining good health and preventing the onset of diabetes and other metabolic disorders. 

Blood sugar or glucose levels can vary based on many factors, including age [5]. The table below helps us understand normal blood sugar levels across different age groups.

Age groupFasting blood sugar (mg/dL)Pre-meal blood sugarPost-meal blood sugarBedtime/overnight (mg/dL)
Toddlers and preschoolers (<6 years)100-180100-180110-200110-200
School-aged children (6-12 years)90-18090-180<180100-180
Teenagers (13-19 years)90-13090-130<180100-180
Young adults (20-60 years)<10090-130<14090-140
Middle-aged and older adults (>60 years)100-12090-130<180100-180

Special notes:

  • Diabetics: Individuals with diabetes might have specific targets determined through consultation with healthcare providers.
  • Values: This table provides a general guideline; individual targets may vary based on personal health conditions and doctor’s advice.
  • Monitoring: Frequent monitoring is advised for high-risk groups and individuals with unstable blood sugar levels.

What is an unhealthy blood sugar level?

An unhealthy blood sugar response can manifest through several key signs, indicating potential health issues such as diabetes or insulin resistance [6]. Common symptoms include:

  • Fatigue: Feeling unusually tired, especially after meals, suggesting inefficient glucose use.
  • Frequent hunger and cravings: Experiencing sudden, intense hunger or a desire for sugary snacks, which result from rapid spikes and drops in blood sugar.
  • Mood swings and irritability: Fluctuating blood sugar levels can lead to emotional instability, irritability, and difficulty concentrating.
  • Blurred vision: Temporary vision changes can occur when high blood sugar levels draw fluid from the eyes.
  • Excessive thirst and urination: These symptoms appear as the body tries to eliminate excess glucose through urine.
  • Slow healing wounds: Elevated blood sugar can impair circulation and nerve function, delaying wound healing.
  • Yeast infections: Frequent infections can develop as excess sugar feeds yeast growth.

Recognizing these signs is crucial for timely intervention and management of blood sugar levels.

How can I improve my blood sugar response?

Maintaining a healthy blood sugar response is crucial for overall well-being and can prevent long-term health complications such as diabetes and cardiovascular disease.

Here are some key lifestyle choices that can significantly improve your blood sugar levels:

Consistent meal timing

Eating your meals and snacks at similar times each day prevents significant fluctuations in blood sugar, aiding in better overall management. Avoid skipping meals, especially breakfast, to maintain stability throughout the day.

Physical activity

Engage in walking, cycling, or swimming for at least 150 minutes weekly. This helps manage blood sugar levels and boosts overall health by reducing the risk of chronic diseases [7].

Advanced testing

Consider using advanced testing options like the Longevity.Technology Epigenetic & DNA Test to gain insights into how genetics influence blood sugar response.

The test can provide personalized information, allowing you to tailor your diet and lifestyle to suit your genetic makeup better.

Adequate hydration

Water aids in metabolizing glucose and helps the kidneys flush out excess sugar through urine. Avoid sugary beverages and opt for water and other non-caloric drinks to maintain optimal blood volume and ensure efficient nutrient and hormone transport throughout the body.

Reduce stress

Chronic stress elevates cortisol levels, which can spike blood sugar [8]. Implement stress-reduction techniques like mindfulness, yoga, or deep breathing exercises. 

Regularly engaging in these activities helps maintain lower stress levels, promoting better blood sugar control and enhancing overall health and well-being.

Sufficient quality sleep

Aim for 7-9 hours per night, establishing a consistent sleep schedule. Enhance your sleep environment by ensuring it is quiet, dark, and comfortable to support uninterrupted and restorative sleep.

Why do we need regular blood glucose monitoring?

Consistent monitoring helps in the early detection of abnormal blood sugar levels [9], which is crucial for preventing the development of diabetes and its associated complications, such as:

  • Heart disease
  • Kidney damage
  • Vision impairment

By monitoring blood sugar fluctuations closely, individuals can make informed decisions about diet, exercise, and medications, thereby actively managing their condition and improving their overall health outcomes. 

Furthermore, regular monitoring allows for adjusting treatment plans in response to blood sugar trends, ensuring timely and effective interventions. 

Routine blood sugar checks empower individuals, providing them with the necessary information to take proactive steps to maintain their health and prevent long-term complications.

What are the most effective supplements to lower blood sugar?

Dietary supplements are widely used to support various aspects of health, including blood sugar management. They can benefit individuals looking to stabilize their glucose levels, especially those at risk of or managing diabetes.


Cinnamon is renowned for its ability to mimic insulin and enhance insulin sensitivity. Regular consumption can help lower fasting blood sugar levels [10]. This popular spice adds flavor to dishes and offers a natural method for managing and improving blood sugar control.

Alpha-lipoic acid (ALA)

Alpha-lipoic acid (ALA) is an antioxidant that enhances insulin sensitivity and aids glucose metabolism, helping to lower fasting blood sugar levels. It also protects against nerve damage, which can alleviate symptoms of peripheral neuropathy, a common complication of diabetes.


Supplementing with chromium can significantly improve insulin sensitivity and reduce blood sugar levels, making it a valuable component in managing diabetes and prediabetes. It also effectively supports carbohydrate and fat metabolism.


Magnesium is vital in over 300 enzymatic reactions, including glucose metabolism. Low magnesium levels are associated with impaired insulin secretion and reduced insulin sensitivity.

Supplementing with magnesium can help regulate blood sugar levels, especially in deficient individuals.


Berberine enhances insulin sensitivity, increases glycolysis, reduces glucose production in the liver, and slows carbohydrate digestion, helping manage blood sugar spikes effectively after meals [11].
