Many of us think of olive oil as a simple salad dressing or frying ingredient. However, recent research and biohacking experience show that high-quality extra virgin olive oil is more like a natural medicine than a simple fat.
In this article, we'll look at the progress of an intriguing 10-day experiment involving three tablespoons of olive oil per day, and explain why this simple habit can make a significant difference to your metabolism, energy levels, and even your waistline.
The science behind the “peppered” bite
Have you ever felt a slight irritation or “bite” in your throat when you swallow a sip of good olive oil? This feeling is not a coincidence. It is oleocanthal – a unique polyphenol found only in fresh, high-quality olive oil.
Oleocanthal has been scientifically proven to act on the same enzymes (COX-1 and COX-2) as ibuprofen, providing anti-inflammatory effects without the side effects of medications. Approximately 50 grams (about 3.5 tablespoons) of the highest quality oil per day provides an anti-inflammatory effect equivalent to approximately 10% of an adult dose of ibuprofen, but is gentle on the stomach and liver.
The 10-day protocol: What to expect?
During the experiment, 3 tablespoons of olive oil were consumed per day: in the morning on an empty stomach, in the afternoon and in the evening – always between meals.
- First 48 hours: The body is adjusting. You may experience a slight feeling of heaviness or bloating as the gallbladder and liver have to work harder to emulsify fats.
- Day 3 – turning point: During this stage, there is usually a rapid reduction in inflammation. Participants report an increase in energy immediately upon waking, a reduction in facial swelling, and weight loss (often due to fluid retention caused by inflammation).
- Day 5 and beyond: “Silent joints.” Thanks to its anti-inflammatory effect, stiffness and discomfort in the knees or elbows after physical exertion are reduced.
- Appetite control: Olive oil affects satiety hormones (such as GLP-1). As a result, cravings for snacks are naturally reduced and the afternoon sugar roller coaster disappears.
Why do fats help burn fat?
Contrary to the outdated belief that “fat makes us fat,” studies (such as the famous PREDIMED study) show that the group that consumed more olive oil lost more weight and waist circumference than the group on a low-fat diet. Olive oil improves insulin signaling and helps the body access stored fat reserves.
PREDIMED study scale: This is one of the largest nutritional studies ever, in which Spanish researchers followed 7,447 people over several years.
Research groups: Participants were divided into three groups:
- Mediterranean diet plus 4 tablespoons of Extra Virgin olive oil daily.
- Mediterranean diet plus mixed nuts.
- Control group with a low-fat diet.
Research results: The olive oil group lost more weight and showed a greater reduction in waist circumference than the low-fat group. This proves that eating healthy fats can promote weight loss, not weight gain.
The impact of the middle road (Frontiers of Nutrition study): Another September 2025 study of 16,273 adults found that people who consumed 2 tablespoons of olive oil at least 6 days a week had an average waist circumference of 10 centimeters smaller (89.1 cm vs. 99.4 cm) than those who consumed the oil occasionally.
Hormonal mechanism: Olive oil helps reduce postprandial glucose spikes. Adding just 10 grams of oil to a meal can reduce the spike in blood sugar by more than 20%, which stabilizes insulin levels and prevents fat storage.
Metabolic thermogenesis: Extra Virgin Olive Oil can increase dietary thermogenesis by approximately 5.1%. This means that the body uses more energy (burns more calories) to process this fat compared to other types of diet.
Appetite regulation: Olive oil stimulates satiety hormones such as cholecystokinin, peptide YY, and leptin, which activate similar pathways as today's popular weight loss medications (GLP-1 receptor agonists).
Important rules to avoid mistakes:
- Use oil BETWEEN meals: Consuming a large dose of oil right after a heavy meal can create a “brick feeling” in the stomach and slow down digestion too much.
- Quality is crucial: Many supermarket oils may be oxidized or even mixed with cheaper oils. Look for oil in a dark glass bottle, with a clear harvest date.
- Test with the “neck test”: If the oil tastes like nothing and causes mild irritation in your throat, it doesn't contain enough polyphenols and you won't get the expected therapeutic effect.
Conclusion
Olive oil is not just a food; it is a powerful tool for balancing the hormonal system and reducing chronic inflammation. By including quality olive oil in your daily routine in the right amounts, you are not only improving your heart health, but also helping your metabolism function more efficiently.
Note: Consult your doctor before making any major changes to your diet, especially if you are taking medication or have a chronic condition.
