Taking a tablespoon of olive oil 15–30 minutes before drinking modestly slows how quickly alcohol enters your bloodstream, by delaying stomach emptying. That can result in a slower, gentler onset of intoxication. What it will not do is prevent a hangover, "coat" your stomach, or reduce your total alcohol absorption for the night — hangovers come from dehydration, acetaldehyde buildup, sleep disruption, and congeners, none of which olive oil touches.
Key Facts
- Real mechanism: dietary fat delays gastric emptying, which slows — not blocks — how fast alcohol reaches the small intestine, where most absorption happens
- Total absorption is unchanged: slower onset is not the same as reduced intoxication or a lower total blood alcohol peak over the evening
- Does not prevent hangovers: hangovers are driven by dehydration, acetaldehyde (a toxic alcohol metabolite), disrupted sleep, and congeners in darker spirits — not by what's in your stomach beforehand
- Typical protocol: about 1 tablespoon (10–15 mL) of extra virgin olive oil, 15–30 minutes before your first drink
- Where it comes from: a genuine Mediterranean pre-drinking tradition (Sicily, Greece, Turkey, southern Spain) that went viral in April 2024 after Benny Blanco described it on The Tonight Show
Does Taking Olive Oil Before Drinking Alcohol Actually Work?
Partially. Consuming fat — including a tablespoon of olive oil — before drinking delays gastric emptying, the rate at which your stomach passes its contents into the small intestine. Since roughly 80% of alcohol absorption happens in the small intestine (versus about 20% in the stomach), slowing that transit modestly delays how quickly alcohol reaches your bloodstream. This can produce a slower, gentler onset of intoxication, particularly if you're drinking on an empty stomach.
What it does not do is change how much alcohol you ultimately absorb over the course of the evening. Slower absorption is a real, measurable effect — reduced total intoxication is not. Your liver still has to process the same total amount of alcohol regardless of how it got there.
Does Olive Oil "Coat" Your Stomach Before Drinking?
No — this specific claim, the one that made the trend go viral, isn't how digestion works. The Association of UK Dietitians has stated plainly that "lining your stomach" isn't a real physiological mechanism. Olive oil mixes with your stomach contents like any other fat and gets digested along with everything else; it doesn't form a protective barrier on the stomach lining. The genuine effect (delayed gastric emptying, described above) is real — it's just a different mechanism than the popular claim describes.
Where Did the Olive-Oil-Before-Drinking Trend Come From?
The practice reached mainstream audiences in April 2024, when music producer Benny Blanco described it on The Tonight Show; his TikTok clip on the topic gathered roughly 1.5 million likes, with commenters across the Mediterranean confirming it as a real family tradition. Regional versions exist across the region: it's passed down through generations in Sicily and southern Italy, it's a common pre-drinking habit in Greece, Turkish raki culture pairs spirits with fatty appetizers that slow absorption over the course of a meal, and similar habits show up in southern Spain. The underlying observation — that people felt intoxicated more slowly — reflects a real physiological effect. The leap from there to "prevents hangovers" is where the trend overstates the science.
How Long Before Drinking Should You Take a Shot of Olive Oil?
15–30 minutes before your first drink is the practical window. Any earlier and the fat has already largely digested, losing its gastric-emptying effect by the time you start drinking; any later, and alcohol absorption has already begun before the fat can slow it down.
How Much Olive Oil Should You Take Before Drinking?
About one tablespoon (10–15 mL) of extra virgin olive oil is the typical dose referenced in both traditional practice and most coverage of the trend. Refined or "light" olive oil won't provide the same polyphenol content, so extra virgin is the version worth using. Taking meaningfully more than a tablespoon on an empty stomach raises the risk of bloating, nausea, or loose stools — the opposite of what you're going for before a night out.
| Strategy | What It Does | How Well It Works |
|---|---|---|
| Olive oil shot (1 tbsp) | Modestly delays gastric emptying, slowing alcohol absorption | Modest — slower onset only, no hangover prevention |
| A balanced meal | Significantly delays alcohol absorption via a larger, mixed dose of fat, protein, and carbohydrate | Strong — the most evidence-supported pre-drinking approach |
| Water between drinks | Slows your overall pace and directly addresses alcohol-driven dehydration | Strong — addresses an actual hangover cause |
| Milk before drinking | Same gastric-emptying mechanism as olive oil | Modest — same effect, same limitations |
| Avoiding darker spirits | Reduces intake of congeners, compounds linked to worse hangover severity | Moderate — reduces the worst hangover types, not all of them |
Does Olive Oil Prevent Hangovers?
No, and this is the central claim the science doesn't support. Hangovers are driven by four main factors, none of which olive oil addresses: dehydration (alcohol suppresses antidiuretic hormone, causing water loss), acetaldehyde toxicity (the toxic intermediate compound produced as your liver metabolizes alcohol), disrupted sleep (alcohol fragments REM sleep even when it helps you fall asleep faster), and congeners (impurities concentrated in darker spirits and red wine that are associated with worse next-day symptoms — Rohsenow & Howland, Current Drug Abuse Reviews, 2010). Olive oil consumption before drinking has no documented effect on any of these four mechanisms. As Mary Flynn of Brown University's Olive Oil Health Initiative has put it: olive oil poses no harm before drinking, but it doesn't deliver a hangover benefit either.
What Actually Prevents (or Reduces) Hangovers?
- Pacing and moderation: the liver metabolizes roughly one standard drink per hour, regardless of what you ate beforehand
- Hydration: water between alcoholic drinks, plus a full glass before bed, directly offsets alcohol's dehydrating effect
- A real meal: a mix of protein, fat, and carbohydrate slows absorption more effectively than a single tablespoon of any one fat
- Sleep: an earlier bedtime and more total sleep help offset the REM disruption alcohol causes
Where Olive Oil Before Drinking Might Genuinely Help
- Slower onset of intoxication — modest, but useful if you're tired or drinking on an empty stomach
- Reduced stomach irritation — a buffer of fat can ease the harshness of alcohol on an empty stomach, particularly for anyone prone to acid reflux
- Behavioral ritual value — the deliberate pause to take a shot of olive oil may nudge you toward more intentional drinking overall: eating real food, hydrating, and pacing yourself
- Polyphenol delivery — oleocanthal, hydroxytyrosol, and oleuropein act as antioxidants amid alcohol-induced oxidative stress (Beauchamp et al., Nature, 2005, on oleocanthal specifically); whether that provides meaningful protection from a single night of drinking, versus consistent daily intake, remains speculative
If You're Going to Try It: Practical Protocol
- Timing: 15–30 minutes before your first drink
- Dosage: about 1 tablespoon (10–15 mL)
- Quality: extra virgin olive oil only — refined versions lose the polyphenols
- Mediterranean variation: some traditions add lemon juice (cuts the oily texture) and cinnamon (mostly flavor)
- Portable format: single-serve packets travel well for bars and restaurants
Frequently Asked Questions
Does olive oil before drinking alcohol actually work?
Partially. It delays gastric emptying, which modestly slows how fast alcohol enters your bloodstream — producing a slower onset of intoxication. It does not reduce total alcohol absorption or prevent a hangover.
Does olive oil prevent hangovers?
No. Hangovers come from dehydration, acetaldehyde toxicity, disrupted sleep, and congeners — none of which olive oil affects. A pre-drinking shot may slow intoxication onset, but it doesn't change next-day symptoms.
How much olive oil should you take before drinking?
About 1 tablespoon (10–15 mL) of extra virgin olive oil is the typical amount. More than that on an empty stomach risks nausea, bloating, or loose stools.
How long before drinking should I take olive oil?
15–30 minutes before your first drink. Earlier and the fat has already digested; later and alcohol absorption has already started.
Does olive oil coat your stomach before drinking?
No — "lining your stomach" isn't a real physiological mechanism. Olive oil mixes with stomach contents like any other fat. The real effect is delayed gastric emptying, which is a different mechanism than the popular "coating" claim.
The Bottom Line
The Mediterranean tradition behind this trend reflects a real physiological effect — a tablespoon of olive oil 15–30 minutes before drinking modestly slows alcohol absorption. The viral claim significantly overstates the benefit: it will not prevent hangovers, protect your liver, or change your total alcohol processing for the night. If the ritual encourages more intentional drinking — eating real food, hydrating, pacing yourself — that behavioral benefit exists independent of the oil's chemistry. The meaningful polyphenol benefits of olive oil come from consistent daily consumption, not a single pre-drinking dose.
