You’ve probably seen the videos. Some influencer or biohacker stands in a sun-drenched kitchen, pours a golden liquid into a shot glass, and knocks it back like they’re at a Friday night rager. Except it’s 7:00 AM. And it’s Extra Virgin Olive Oil.
It looks intense. Maybe even a little gross if you aren't used to the peppery kick of high-quality polyphenols hitting the back of your throat. But it’s not just a social media trend. People have been doing this in the Mediterranean for centuries. So, what does a shot of olive oil do once it actually hits your system?
Is it a miracle cure for bloating, or just a calorie bomb? The answer is somewhere in between, rooted in fascinating biochemistry and a bit of old-world wisdom.
The Immediate Impact on Your Digestive System
The first thing you’ll notice is the texture. It’s viscous. When you take a shot of olive oil, it coats the lining of the esophagus and the stomach. This isn't just a physical sensation; it triggers a hormonal cascade.
For many, the primary reason to do this is "regularity." Olive oil acts as a mild, natural lubricant for the digestive tract. It stimulates the production of bile and digestive enzymes. If you struggle with sluggish bowels, that morning shot can act as a gentle nudge to get things moving. It’s essentially "greasing the wheels," but on a cellular level.
Researchers have looked into how these fats interact with the gallbladder. When you consume a concentrated dose of fat, your gallbladder contracts to release bile to break it down. This process helps keep the gallbladder functioning efficiently, potentially reducing the risk of gallstones, though you should always check with a doctor if you already have gallbladder issues.
Why Your Heart Might Love This Habit
We can't talk about olive oil without mentioning the PREDIMED study. This was a massive, landmark clinical trial in Spain that followed thousands of people at high cardiovascular risk. The results were pretty clear: those eating a Mediterranean diet supplemented with extra-virgin olive oil had significantly lower rates of major cardiovascular events.
Why? It’s the monounsaturated fatty acids (MUFAs), specifically oleic acid.

When you take a shot of olive oil, you are flooding your bloodstream with these MUFAs. They help lower LDL cholesterol (the "bad" kind) without tanking your HDL (the "good" kind). It's a delicate balancing act. Most modern diets are way too high in Omega-6 fats from seed oils, which can be pro-inflammatory. Swapping those for the stable, heart-healthy fats in olive oil changes the fatty acid profile of your cell membranes.
It makes them more fluid. More resilient.
The Polyphenol Punch: More Than Just Fat
If you buy the cheap, refined stuff in the plastic clear bottle, you’re missing the point. You want the stuff that makes you cough.
That peppery sting is caused by oleocanthal. This is a specific type of polyphenol found in extra virgin olive oil that has been shown to have anti-inflammatory effects remarkably similar to ibuprofen. Think of it as a natural, low-dose anti-inflammatory shot.
- Oleuropein: Helps prevent the oxidation of LDL cholesterol.
- Hydroxytyrosol: One of the most powerful antioxidants found in nature, capable of crossing the blood-brain barrier.
- Vitamin E and K: Essential fat-soluble vitamins that require—you guessed it—fat to be absorbed.
A shot of olive oil provides the perfect vehicle for these nutrients. Because they are already dissolved in the oil, your body doesn't have to work hard to scavenge them from a complex meal. They are ready for uptake almost immediately.
Blood Sugar and Satiety
One of the coolest things about what a shot of olive oil does is how it handles your next meal.
Fat slows down gastric emptying. This is a fancy way of saying it keeps food in your stomach longer. If you take a shot of olive oil before a meal—especially one that contains carbohydrates—you're going to see a much flatter blood sugar curve.

Instead of a massive spike and a subsequent "food coma" crash, the oil ensures a slow, steady release of glucose into the blood. Honestly, it’s a game-changer for people who get "hangry" or deal with mid-afternoon energy slumps. You feel fuller. You feel more stable.
The Skin and Glow Factor
It sounds like a cliché, but "beauty from within" is a real biological process. The squalene and vitamin E in olive oil are vital for skin health. Squalene is a natural component of human sebum; it helps maintain the skin’s moisture barrier.
By consuming olive oil internally, you’re providing the raw materials your body needs to repair skin cells damaged by UV exposure and pollution. It’s not going to replace your sunscreen, but it builds a better foundation from the inside out.
What Most People Get Wrong
You shouldn't just grab any bottle off the shelf and start chugging. There are some serious pitfalls here.
First, calories matter. A standard "shot" (about two tablespoons) is roughly 240 calories. If you add that on top of a surplus of food, you’re going to gain weight. The key is replacement. If you’re taking the shot, maybe skip the butter on your toast or the heavy cream in your coffee.
Second, the "Extra Virgin" label is often faked. The olive oil industry is notorious for fraud, sometimes cutting expensive oil with cheap soybean or hazelnut oil. If your oil doesn't have a harvest date, a dark glass bottle to protect it from light, and a slightly bitter, peppery taste, it’s probably not giving you the health benefits you’re looking for. Look for certifications like COOC (California Olive Oil Council) or PDO (Protected Designation of Origin) from European regions.
Practical Insights for Starting the Habit
If you're ready to try it, don't just dive into a double-shot. Your stomach might rebel.

Start with a single teaspoon. See how your digestion reacts. Some people find it causes a bit of urgency if they aren't used to high fat intake. Over a week, you can work your way up to a tablespoon or two.
The Best Time to Take It:
Most experts recommend taking it on an empty stomach in the morning. This allows for maximum interaction with the gut lining and sets the tone for your blood sugar levels for the rest of the day. However, if you find it a bit heavy, taking it 15 minutes before your largest meal of the day is a great alternative.
The Quality Check:
Pour a little into a glass. Warm it with your hands. Smell it. It should smell like fresh grass, tomatoes, or artichokes. If it smells like crayons or old peanuts, it’s rancid. Throw it out. Rancid oil is pro-inflammatory, which defeats the entire purpose of the ritual.
Flavor Pairing:
If you can’t stand the taste of straight oil, squeeze a little fresh lemon juice into the shot. The acidity cuts through the fat and adds a boost of Vitamin C, which actually helps with the absorption of certain antioxidants in the oil. It’s a classic Mediterranean combo for a reason.
Final Takeaway on the Olive Oil Shot
Taking a shot of olive oil isn't a magic wand that fixes a poor diet. It won't cancel out a midnight run for fast food. But as a tool in a broader health strategy? It’s incredibly effective. It targets inflammation, supports the heart, stabilizes blood sugar, and keeps your digestive system on a schedule.
It’s a small, 30-second habit that leverages some of the most studied fats on the planet. Just make sure you’re buying the good stuff—your arteries (and your skin) will thank you.
Next Steps for Implementation:
- Check your pantry: If your current oil is in a clear plastic bottle or past its "best by" date, replace it with a high-quality, cold-pressed Extra Virgin Olive Oil in dark glass.
- Start small: Begin with one teaspoon tomorrow morning. Observe your energy levels and digestion throughout the afternoon.
- Monitor your total fat intake: Ensure the added calories from the shot are balanced by reducing refined fats elsewhere in your day to maintain a healthy caloric balance.
- Listen to the "kick": Pay attention to the throat sting. That’s the oleocanthal working; if you don't feel it, look for a "high-polyphenol" specific brand for your next bottle.
