You’ve probably seen the videos. Someone stands in a kitchen, pours a thick, golden glug of extra virgin olive oil into a shot glass, and knocks it back with a grimace or a shrug. It looks like a bizarre TikTok dare, but the practice of taking olive oil before drinking alcohol is actually an old Mediterranean "hack" that’s recently gone global. People swear by it. They claim it’s the secret to waking up without that jackhammer-against-the-skull feeling the morning after a big night out.
But does it work?
Or is it just a greasy placebo? Honestly, the science behind it is a bit more nuanced than most influencers lead you to believe. It isn't a magic shield. You can't drink a gallon of vodka and expect a tablespoon of oil to save your soul. However, there is a very real physiological reason why fat interacts with alcohol absorption. It’s about the "gastric emptying" rate. Basically, your stomach is a gatekeeper. When you dump fat into it, the gate closes halfway.
How olive oil before drinking actually affects your body
The logic is pretty straightforward if you think about how digestion works. Alcohol is absorbed mostly in the small intestine, not the stomach. When you drink on an empty stomach, the liquid rushes straight through the pyloric sphincter—that’s the valve at the bottom of your stomach—and hits your bloodstream almost instantly. This is why that first glass of wine on an empty stomach makes you feel floaty within ten minutes.

By taking olive oil before drinking, you're introducing a concentrated dose of healthy monounsaturated fats. Fat takes a long time to break down. While your stomach is busy trying to figure out what to do with that shot of liquid fat, it keeps the pyloric sphincter closed. This slows down the rate at which any subsequent alcohol enters the small intestine. It’s "lining the stomach," but not in the way people think. It’s not like a waterproof coating on a jacket. It’s a speed bump.
There was a famous anecdote involving billionaire Sir Richard Branson, who reportedly learned this trick from a friend. He claimed it helped him stay sharp during long nights of socializing. While Branson isn't a doctor, the biology holds up: slower absorption means your liver has a fighting chance to keep up with the acetaldehyde—the toxic byproduct of alcohol metabolism—instead of being completely overwhelmed by a sudden flood of booze.
The Mediterranean secret or just common sense?
In places like Greece, Italy, and Spain, eating fatty appetizers like olives, cheese, or bread dipped in oil before the main meal is standard practice. They’ve been doing "olive oil before drinking" for centuries without calling it a biohack. It’s just dinner.
Modern research on the Mediterranean diet often focuses on heart health, but the anti-inflammatory properties are the real heroes here. Alcohol is a massive inflammatory trigger. It irritates the lining of the gut and causes oxidative stress. Extra virgin olive oil (EVOO) is packed with polyphenols like oleocanthal. This specific compound actually mimics the effect of ibuprofen in the body. It’s a natural anti-inflammatory. So, while the oil is slowing down the alcohol, those polyphenols are potentially pre-gaming your system to handle the inflammation that’s about to hit.

The catch: What the "hacks" get wrong
Let's be real for a second. If you take a shot of olive oil and then head out for ten rounds of tequila, you’re still going to be drunk. You’re still going to be dehydrated. And you’re probably still going to feel like garbage the next day. The oil doesn't eliminate the alcohol; it just delays the peak.
One big mistake people make is thinking the quality of the oil doesn't matter. If you’re using cheap, refined "light" olive oil, you’re missing the polyphenols. You’re just drinking grease. You need the high-end stuff—the kind that peppers the back of your throat. That pepperiness is the oleocanthal. That’s the medicine.
Also, some people find that a shot of pure oil on an empty stomach causes "gastric distress." To put it bluntly: it can give you the runs. Fat can stimulate the gallbladder to release bile, and for some, that leads to an emergency trip to the bathroom before they’ve even finished their first beer. It’s a risky game if your stomach isn't used to high fat intake.
Better ways to use olive oil before drinking
You don't necessarily have to take a shot of it straight. That’s kinda gross for most people.
A better approach? A hearty salad drenched in extra virgin olive oil, or even some high-quality sourdough dipped in a generous amount of the stuff. You get the same "speed bump" effect on your digestion without the nausea of drinking straight oil. Plus, the fiber in the bread or veggies helps even more.
- Choose Extra Virgin: Ensure it's cold-pressed to keep the antioxidants intact.
- Timing: Take it about 20 to 30 minutes before your first drink.
- Quantity: A single tablespoon is usually enough. More isn't necessarily better; it’s just more calories.
Myth vs. Reality: The hangover "cure"
Can olive oil prevent a hangover? Not entirely.
Hangovers are a multi-headed beast. They are caused by dehydration, electrolyte imbalance, sleep deprivation, and the buildup of acetaldehyde. Olive oil only helps with the rate of absorption and the initial inflammatory response. It does nothing for the fact that alcohol is a diuretic that makes you pee out all your potassium and magnesium.
If you want to actually survive the night, you have to pair the olive oil strategy with hydration. The old "one glass of water for every drink" rule is boring, but it’s the gold standard for a reason. Olive oil is the shield, but water is the repair crew.
Interestingly, some studies, including research published in journals like Nature, have highlighted how oleocanthal specifically targets the same inflammatory pathways as NSAIDs. This suggests that the Mediterranean habit of consuming oil might actually provide a baseline level of protection against the systemic "burn" that alcohol causes. But again, it’s a supplement to responsible habits, not a replacement for them.
What the experts say
Dietitians often point out that while the "lining the stomach" theory is technically a simplification, the impact on blood sugar is real. Alcohol can cause your blood sugar to spike and then crash, leading to that shaky, weak feeling. Consuming a fat like olive oil stabilizes your blood sugar response. This prevents the "hangry" feeling that leads to 2:00 AM pizza runs, which, let's be honest, usually makes the morning after feel even worse.
Dr. Simon Nassir, a nutrition specialist, often notes that the biggest benefit isn't the oil itself, but what it replaces. If you're focusing on healthy fats before an event, you're less likely to arrive with a completely empty stomach, which is the number one mistake people make when consuming alcohol.
How to actually do this without gagging
If you’re dead set on trying the "shot" method, don't just use whatever is in the plastic bottle under your sink. Get a high-phenolic oil. Look for brands that list the harvest date.
- The "Lush" Method: Mix a tablespoon of olive oil with a little squeeze of lemon juice. It cuts the greasiness and makes it go down way easier.
- The Snack Method: Eat five or six large, oil-cured olives. You get the fats, the salt (which helps with electrolytes), and it feels like a normal human snack.
- The Infusion: Some people infuse their oil with rosemary or garlic. It doesn't change the alcohol interaction, but it makes the experience less like taking cough syrup.
The Verdict
Taking olive oil before drinking is a legitimate physiological strategy to slow down alcohol absorption and mitigate some inflammation. It is backed by the basic principles of biology—fat slows gastric emptying. It isn't a miracle. It won't make you bulletproof. But in the hierarchy of "hangover prevention" myths, this one is actually based on how the human body functions.
If you’re going to a wedding or a long dinner party, a bit of olive oil is a smart move. Just don't forget the water. And maybe don't brag about it too loudly at the bar—nobody likes a biohacker in the middle of a happy hour.

Actionable Next Steps
If you want to test the effects of olive oil before drinking, start small. Don't try a full shot of oil for the first time right before a major event in case your stomach reacts poorly to the fat. Instead, try a tablespoon of high-quality Extra Virgin Olive Oil (EVOO) mixed into a small snack about 30 minutes before you plan to have your first drink. Focus on oils that have a "peppery" finish, as this indicates higher levels of the anti-inflammatory compound oleocanthal. Most importantly, keep your hydration levels high throughout the night; olive oil can slow the alcohol's entry into your system, but it won't stop the dehydration that causes the majority of hangover symptoms.
