The easy test that can reveal your biological age

The way your body reacts to sugar is unique, and there's a test you can take to identify it.

I have long stated and emphasized in my articles and videos: each human organism is truly unique, and so is its configuration in terms of physical adaptation, nutritional absorption, stress management, rest, and even the way it manifests vulnerabilities and diseases.

A recent publication in the journal Nature corroborates this with another particularity of your body, which is that, depending on your metabolic health, it can indicate whether you are insulin-resistant, or, on the contrary, insulin-sensitive; whether you are prediabetic and more.

It's important to know how your body absorbs and uses sugar. I'm a bit stubborn about what this means for your health, but here you'll see how to rebalance it.

Glucose is sugar. Yes, it's that simple. When you eat a piece of bread, an apple, or any food containing carbohydrates, your body converts it into glucose during digestion. This glucose enters the bloodstream and is transported throughout your body to provide energy to your cells.

Your body needs glucose; it's one of the fuels that powers it, especially your brain, muscles, and organs. However, the problem isn't with glucose itself, but with how your body handles it and how it's distributed over time.

Your blood glucose level is like a graph that goes up and down. Ideally, it should rise slowly after eating and remain stable. The problematic part is when it rises very quickly, reaches high peaks, and then drops sharply. These abrupt changes are what we call glucose spikes,

and they occur when, after eating, your blood sugar level rapidly increases to very high values. This happens especially when you consume foods rich in refined carbohydrates: white bread, rice, sweets, soft drinks, or cookies.

At that moment, your pancreas (a gland in your abdomen) perceives this glucose spike and releases insulin, the hormone that acts as a "key" allowing glucose to enter your cells. When spikes are frequent and severe, your pancreas constantly overworks, and your cells begin to become "deaf" to insulin. This is called insulin resistance.

Frequent glucose spikes can cause several problems:

• Chronic inflammation in your body, linked to accelerated aging, heart problems, and autoimmune diseases.

• Fatigue and mood swings: After each spike, there's a sharp drop in glucose, which leaves your energy depleted, and you feel tired, irritable, and have difficulty concentrating.

• Weight gain: Insulin resistance causes your body to store more fat, especially in the abdominal area.

• Risk of type 2 diabetes: If spikes are very frequent for years, your cells simply stop responding to insulin, which is known as diabetes.

• Accelerated aging: Excess glucose adheres to proteins in your body in a process called glycation, which damages the structure of your tissues and accelerates aging.

• Cardiovascular problems: Glucose spikes damage arteries and increase the risk of heart attacks and strokes.

These effects don't happen overnight; they accumulate over the years. That's why it's crucial to learn to control spikes now, before they cause serious problems.

The study that identified that not all of us process glucose in the same way

The study published by NATURE indicates that we do not all process glucose in the same way. The key is that your body can respond according to the type of carbohydrate consumed, to its particular metabolic state!

Individual but consistent variability:

In this study, responses varied from person to person depending on their metabolism (not the carbohydrates themselves), and each individual maintained consistent patterns, meaning if your insulin spikes with rice today, it will spike similarly later.

5 types of responses based on the food that causes the highest peak. For example, if the person reacted to consuming:

1 potatoes → tends towards insulin resistance ⚠️: Cells do not respond well to insulin. Higher fasting glucose and high triglycerides. Would indicate signs of prediabetes and cardiovascular risk.

2 grapes → tends to have Better metabolic health ✅. That is, would have greater insulin sensitivity, lower fasting glucose and triglycerides. Meaning, your body handles sugar efficiently.

3 bread → the person tends to have elevated blood pressure ⚠️ Hypertension (systolic and diastolic). Molecules associated with cardiovascular risk. There may be a hidden risk, even if glucose appears normal.

Conclusion: your "problem carbohydrate" type reveals your true metabolic profile.

This happens because several factors influence how your body handles glucose:

• Your gut microbiota (the bacteria in your gut)

• Your genetic makeup

• Your physical activity level

• Your stress and sleep quality

• Your age and sex

• Medications you take

•  Your Body Weight This means that a diet that works perfectly for your neighbor might not work for you. That's why it's so important to understand your own body and how you specifically respond to food.

How do I know if I have glucose spikes?

Although not all symptoms are obvious, you may observe:

•  Extreme fatigue after meals

•  Sudden mood swings or irritability

•  Difficulty concentrating ("brain fog")

•  Sugar or carbohydrate cravings

•  Constant hunger a few hours after eating

•  Unexplained weight gain

•  Dry skin or acne

•  Occasional blurry vision

The real causes of glucose spikes (and no, it's not necessarily just "eating sugar")

Although many people believe that glucose spikes only come from sugar and sweets, the reality is more complex:

 First: Good metabolic function promotes good mitochondrial function and vice versa

Mitochondria contribute to energy production from glucose, fats, and other energy sources, and their function is closely related to overall metabolic health, good insulin sensitivity, and cellular stress.

Mitochondria are the "power plants" of your cells. When they function well, your body metabolizes glucose efficiently and responds appropriately to insulin, among other important functions. However, an excess of glucose can be harmful rather than beneficial. In other words, mitochondria need fuel, but an excess of glucose over time can lead to their dysfunction.

How do you know if you have mitochondrial dysfunction?

    •      Chronic fatigue disproportionate to your activity level

    •      Persistent brain fog

    •      Very slow metabolism

    •      Thermoregulation problems (extreme sensitivity to cold or heat)

    •      Slow recovery from exercise

    •      Abnormal glycemic response (unexpected or erratic spikes)

 

How to restore mitochondrial function:

    •      Moderate intermittent fasting

    •      Variable intensity exercise (including strength training)

    •      Strategic supplementation (CoQ10, carnitine, creatine, under supervision)

    •      Sleep optimization and chronic stress reduction

    •      Controlled cold exposure

    •      Avoid mitochondrial toxins (pesticides, heavy metals, some medications) 

2. Second: Implement glycemic control strategies (once mitochondrial function is restored)

 Once you feel your mitochondrial function has improved, your body will be better prepared to respond to the following strategies:

 

A.   The order of food matters 

Try to eat in this order:

    1      fiber first (vegetables, salads) unless you have just broken a fast or completed a workout, especially strength training. In that case, I would suggest consuming protein first to rebuild tissue.

    2      protein second (meats, eggs, legumes)

    3      carbohydrates last (rice, bread, potatoes)

Why does it work? Fiber slows glucose absorption. Protein stimulates satiety and stabilizes insulin levels. By eating carbohydrates last, glucose is absorbed more slowly, preventing spikes.

B.    Strategic food combinations

     •      Try to consume carbohydrates that contain healthy fats (olive oil, avocado, nuts)

    •      Never eat refined carbohydrates alone — try, as much as possible, to pair them with protein

    •      Fats slow down digestion and glucose absorption

C.   Timing and frequency

    •   Try to eat within narrower time windows (light intermittent fasting)

    •   Avoid snacking between meals — this keeps insulin stable

    •   A break of at least 4-5 hours between meals allows insulin to drop

 

3. Third: Optimize physical movement (complements all of the above)

Exercise is the most potent "medicine" for insulin sensitivity. But not all types of exercise are equal.

A. Walking after eating (the most underrated strategy)

    •      Walk 2-3 minutes after each meal — especially after carbohydrate-rich meals.  This reduces glucose spikes by up to 30% and doesn't need to be intense — a slow walk works because muscles use glucose directly without needing insulin.

B. Resistance training (weightlifting)

    •      2-3 times a week, 20-30 minutes.  Try to focus on functional training as it helps build muscle mass, which is the body's main "glucose sink." 

C. Moderate cardiovascular exercise

    •      3-4 times a week, 20-30 minutes at moderate intensity

    •      Walking, swimming, cycling, or light jogging. 

 D. HIIT (High-Intensity Interval Training) — with caution and if you already have good insulin sensitivity.  1-2 times a week is effective

 

4. Fourth: Optimize sleep and recovery

Most people don't know that lack of sleep worsens insulin resistance by 25-30% in just one night.

A. Basic sleep hygiene: As much as possible, try to sleep 7-9 hours, in complete darkness.  Try to maintain a room temperature between 16-18°C and avoid blue light from screens 1-2 hours before bed

B. Chronic stress increases blood glucose (even without eating).  So, besides being aware of stress management, additional practices such as meditation, deep breathing, yoga (10-20 minutes), or nature walks can help.

C. Exposure to sunlight within the first hour of waking (10-20 minutes) regulates the circadian rhythm. This improves insulin sensitivity and glucose metabolism.

 

5. Fifth: Strategic supplements (only AFTER the above)

Here are some supplements that could accelerate results

A. Chromium: 200 mcg/day improves insulin sensitivity, especially useful if you have carbohydrate cravings

B. Berberine: 500 mg, 2 times a day is as effective as metformin in improving insulin sensitivity. You can take it before meals

C. Omega-3 (EPA/DHA): 2-3 grams/day (especially EPA) reduces inflammation and improves insulin sensitivity.

E. Magnesium bisglycinate: 400-500 mg before bed regulates glucose and improves sleep. 

F. Vitamin D: Vitamin D deficiency strongly correlates with insulin resistance. If you have a deficiency (level < 30 ng/ml), about 5000 IU daily. And even better if combined with Vitamin K2 to fix calcium in the right places.

Insulin resistance is not a death sentence — it's a signal that your body needs specific changes. These pillars we've explored (nutrition, intermittent fasting, movement, sleep, and strategic supplements) are not complicated or expensive, but they require consistency. Most people see significant improvements in 4-8 weeks if implemented correctly. 

Remember that you don't need to do everything perfectly from day one. Start by improving your nutrition and consider intermittent fasting.  Add movement as you can, and optimize sleep in parallel. Supplements are the complement, not the foundation. Your insulin sensitivity can improve dramatically if you give your body the right tools — you now have the map.
