Is 2 Tablespoons of Olive Oil a Day Too Much?

Two tablespoons of olive oil per day is not too much. It falls comfortably within the range studied in major clinical trials and large cohort studies, where daily intakes often reached three to four tablespoons without adverse effects. The roughly 240 calories in two tablespoons do warrant attention if you are watching your overall energy intake, but the weight of evidence suggests this amount delivers meaningful cardiovascular, metabolic, and liver-health benefits, especially when it replaces less healthful fats rather than simply being added on top of everything else you already eat.

What the Big Studies Actually Used

The concern behind the question usually boils down to calories: olive oil is pure fat, after all, and two tablespoons contain about 28 grams of fat. But clinical trials have routinely assigned participants far more than that. The landmark PREDIMED trial, one of the largest randomized studies of the Mediterranean diet, gave its olive-oil group roughly a liter of extra-virgin olive oil per week, working out to about four tablespoons a day. That group saw a roughly 31% lower rate of major cardiovascular events compared to the control diet.

Within the PREDIMED cohort, researchers also looked at how much olive oil people actually consumed and what happened as intake climbed. Participants in the highest third of total olive oil consumption had a 35% lower risk of cardiovascular disease compared to those in the lowest third, and those in the highest third of extra-virgin olive oil consumption specifically had a 39% lower risk. Each additional 10 grams per day of extra-virgin olive oil was linked to a 10% drop in cardiovascular disease risk and a 7% drop in cardiovascular mortality.¹ Two tablespoons is about 28 grams, so by that math, going from zero to two tablespoons captures a substantial share of the observed benefit.

A separate analysis from three large U.S. cohorts found that people consuming more than half a tablespoon per day had a 14% lower risk of cardiovascular disease overall and an 18% lower risk of coronary heart disease compared to non-consumers.² Half a tablespoon was the threshold for benefit in that study, which puts two tablespoons well into the beneficial range rather than the excessive one.

The Calorie Question and Weight Gain

Two tablespoons of olive oil add about 240 calories to your day. If you pour them over a salad on top of your usual meals without changing anything else, those calories count. But the research on olive oil and body weight tells a more interesting story than simple calorie math would predict.

An analysis of three large U.S. prospective cohorts found that each additional half-tablespoon of olive oil per day was associated with a small but consistent decrease in body weight over time, while equal amounts of butter, margarine, and other vegetable oils were linked to weight gain. Substituting olive oil for those other fats was associated with less weight gain across age groups and body sizes.³ A Spanish cohort study of people following a Mediterranean-style diet found a similar pattern: high olive oil consumers did not weigh more than low consumers and showed no increased risk of becoming overweight or obese.⁴

The likely explanation is behavioral. People who use olive oil tend to use it in place of other fats, not in addition to them. Olive oil’s strong flavor also means a drizzle goes a long way on food, and meals built around olive oil tend to feature vegetables, legumes, and whole grains rather than processed foods. So the practical advice is straightforward: if your two tablespoons are replacing butter on bread, mayo in a dressing, or cooking spray in a pan, you are unlikely to see weight gain. If they are stacking on top of an already calorie-heavy diet with no substitution, the math eventually catches up.

Blood Pressure and Blood Vessel Function

Some of the most striking short-term effects of olive oil show up in blood pressure and the health of blood vessel linings. A trial in young women with mildly elevated blood pressure found that a diet rich in polyphenol-containing olive oil lowered systolic blood pressure by about 8 mmHg and diastolic by about 7 mmHg, while also improving markers of blood vessel function and reducing oxidative stress on LDL cholesterol.⁵ Those are clinically meaningful drops, on par with what some medications achieve.

A systematic review and meta-analysis of trials examining olive oil and vascular function found that olive oil interventions significantly improved flow-mediated dilation, a measure of how well arteries relax in response to increased blood flow. The review concluded that olive oil likely contributes to the cardiovascular protection seen with Mediterranean-style diets through effects on both inflammation and endothelial function.⁶ These vascular benefits appear to be driven largely by the polyphenol content of extra-virgin olive oil rather than the fat itself, which matters when choosing which olive oil to buy.

What Happens to Your Cholesterol

People sometimes worry that adding fat will wreck their lipid panel. The picture with olive oil is more reassuring than you might expect, though also less dramatic than some enthusiasts claim.

A dose-response meta-analysis of randomized controlled trials found that each additional 10 grams per day of olive oil had minimal effects on total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.⁷ In other words, adding olive oil to your diet is unlikely to meaningfully raise your bad cholesterol or triglycerides. A crossover trial that had participants consume extra-virgin olive oil daily found small increases in HDL (the protective kind), with both low-polyphenol and high-polyphenol olive oils raising it modestly. LDL nudged up slightly in the high-polyphenol group, but the difference between the two oils was not significant.⁸

The overall takeaway from the lipid data is that olive oil is close to neutral on standard cholesterol numbers, with a slight tilt toward favorable changes in HDL. Its cardiovascular benefit seems to come more from anti-inflammatory and antioxidant effects than from directly reshaping your lipid panel.

Blood Sugar and Insulin Sensitivity

A large meta-analysis of 51 randomized controlled trials found that olive oil consumption overall did not produce statistically significant changes in fasting blood glucose, insulin levels, or hemoglobin A1c. However, the dose-response analysis revealed something more specific: daily intakes in the range of roughly 25 to 50 grams (about two to three and a half tablespoons) were associated with meaningful improvement in insulin resistance as measured by the HOMA-IR index.⁹ Two tablespoons falls right at the lower end of that window.

Observational data from two large cohorts of U.S. women showed that consuming more than one tablespoon of olive oil daily was associated with a 10% lower risk of type 2 diabetes compared to never consuming it. When researchers modeled what would happen if women replaced butter, margarine, or mayonnaise with an equivalent amount of olive oil, the estimated risk reductions were even larger, ranging from 5% to 15% depending on what was being replaced.¹⁰ Again, the substitution principle matters: olive oil’s metabolic benefits are most apparent when it takes the place of less healthy fats.

Liver Health

Nonalcoholic fatty liver disease is extremely common, and diet is one of the few levers people have for managing it. Olive oil has shown real promise here. A review of studies found that olive oil decreases fat accumulation in the liver, improves post-meal triglyceride handling, and reduces inflammatory signaling that contributes to liver damage.¹¹ A systematic review of clinical trials using ultrasound to assess liver fat found significant reductions in fatty liver grading among participants given olive oil.¹²

One large Italian population study (the MICOL study) sorted people into three tiers of extra-virgin olive oil intake: up to about two tablespoons a day, two to three tablespoons, and more than three tablespoons. Those in the highest tier had roughly a 27% lower prevalence of fatty liver disease compared to the lowest tier. The protective effect was especially pronounced in people with obesity, where the relative risk reduction was about 26%.¹³ Two tablespoons a day actually lands in the lowest tier of that study, which suggests that even at this moderate level there is benefit, and going higher could add more.

What You Replace Matters More Than the Amount

A consistent finding across many of these studies is that olive oil’s health impact depends heavily on what it displaces in your diet. A 2025 study from JAMA Internal Medicine examined how different fats related to mortality risk across large U.S. cohorts and found that substituting 10 grams per day of butter with the same amount of plant-based oil was associated with an estimated 17% lower total mortality and a 17% lower cancer mortality.¹⁴ Olive oil specifically showed an 8% lower mortality risk per 5-gram daily increment.

Another large prospective study estimated that replacing 10 grams per day of margarine, butter, mayonnaise, or dairy fat with olive oil was associated with 8% to 34% lower risk of total and cause-specific mortality. Interestingly, when olive oil was compared to other vegetable oils as a group, no significant difference emerged.¹⁵ This is a useful reality check: olive oil’s biggest advantage is over solid fats and processed spreads. Against other liquid plant oils, the edge is smaller and less clear. If you are already cooking with canola or avocado oil and eating well, switching to olive oil is probably fine but is not going to transform your health. If you are eating a lot of butter, margarine, and mayo, swapping in olive oil is one of the highest-impact dietary changes available.

Extra Virgin Versus Refined

Not all olive oil delivers the same package of benefits. The cardiovascular and metabolic effects described above lean heavily on research using extra-virgin olive oil, which is mechanically extracted and retains its polyphenol content. Refined olive oil (often labeled simply “olive oil” or “light olive oil”) has been stripped of most polyphenols during processing while retaining the same fatty acid profile.

Polyphenols like oleocanthal and oleacein are the compounds responsible for extra-virgin olive oil’s peppery bite, and they carry anti-inflammatory and antioxidant properties that have been studied specifically in people with obesity and prediabetes.¹⁶ The blood pressure reductions and vascular improvements discussed earlier were seen specifically with polyphenol-rich olive oil, not with low-polyphenol versions. So if you are going to commit to two tablespoons a day, extra-virgin is the version worth buying.

One common worry is that cooking destroys these compounds. Research on thermal stability suggests extra-virgin olive oil holds up well under typical home cooking temperatures. Its fatty acid profile and minor constituents keep it more stable at high heat than many other vegetable oils.¹⁷ Deep frying for extended periods will degrade polyphenols, but sautéing, roasting, and even pan-frying at normal temperatures do not wreck the oil. Using extra-virgin olive oil for cooking is perfectly reasonable.

Helping Your Body Absorb Other Nutrients

An underappreciated benefit of including fat with your vegetables is that many plant nutrients are fat-soluble and need dietary fat to be absorbed. Olive oil seems to be particularly good at this job. Animal studies have shown that olive oil, rich in oleic acid, enhanced the intestinal absorption and bioavailability of lutein (a carotenoid important for eye health) significantly more than other vegetable oils.¹⁸ Broader research on carotenoid absorption has confirmed that oleic acid and olive oil enhance the intestinal accessibility of carotenoids more than oils rich in polyunsaturated fatty acids.¹⁹

This has a practical implication: drizzling olive oil on a salad or roasting vegetables in it does not just add flavor. It actually helps your body get more out of the carotenoids in tomatoes, carrots, leafy greens, and peppers. Two tablespoons across a day’s meals is more than enough to facilitate this effect.

Your Genetics May Shift the Response

One reason dietary advice sometimes seems contradictory is that people genuinely respond differently to the same food, and some of that variation is genetic. Research on a gene involved in cholesterol metabolism (APOE) has shown that certain genetic variants respond much more favorably to diets high in monounsaturated fat. In one trial, people carrying a specific APOE variant saw a significant drop in total cholesterol when they switched from saturated fat to monounsaturated fat, while people with other variants of the same gene saw little change.²⁰

Similarly, a study following coronary heart disease patients on a Mediterranean diet for three years found that carriers of certain APOE variants experienced significantly greater reductions in postprandial triglycerides compared to non-carriers.²¹ None of this means olive oil is bad for people with a less favorable genotype; it just means the magnitude of benefit varies. Most people will not know their APOE status, and the population-level evidence for olive oil’s benefits is strong regardless. But it helps explain why your neighbor might swear olive oil transformed their cholesterol numbers while yours barely budge.

When Two Tablespoons Might Actually Be Too Little

Given that the PREDIMED trial used about four tablespoons a day, and the MICOL liver-health study found the strongest protection at intakes above three tablespoons, two tablespoons per day is arguably on the conservative side. Mediterranean countries where olive oil is a dietary staple average well above two tablespoons, and these populations consistently show lower rates of heart disease and certain cancers.

That said, the cardiovascular outcome data from U.S. cohorts suggests benefits begin at as little as half a tablespoon daily, with a relatively smooth dose-response curve upward.² Two tablespoons is a sensible middle ground for someone eating a typical Western diet: enough to capture most of the documented benefits, easy enough to fit into meals without feeling like you are chugging oil, and not so much that the calorie load becomes a concern. If your diet already leans Mediterranean and you enjoy olive oil, going to three tablespoons is well supported by the evidence. If you are just starting to incorporate it, two tablespoons is a solid and sustainable daily target.

Potential Digestive Effects at Higher Intakes

Olive oil has mild laxative properties, and some people notice looser stools when they suddenly increase their intake. This is more common at three to four tablespoons per day than at two, and it tends to resolve as the digestive system adjusts over a week or two. Starting with one tablespoon and working up is a reasonable approach if you are concerned. People with gallbladder problems should be more cautious with any concentrated fat source, olive oil included, because fat stimulates bile release and can trigger pain in someone with gallstones. Two tablespoons is unlikely to cause issues for most people, but if you have had gallbladder attacks, it is worth discussing with your doctor before making olive oil a daily fixture.

Animal research has also explored how olive oil interacts with the gut microbiome, with early evidence suggesting that diets rich in extra-virgin olive oil may shift gut bacteria toward a more protective composition.²² This line of research is still young and mostly based on animal models, so it is too early to make strong claims. But it is another area where olive oil’s effects appear to extend beyond simple nutrition.
