You're standing over a pan, the heat is rising, and you tilt that green glass bottle. A glug here, a splash there. It feels healthy because, well, it’s olive oil. We’ve been told for decades that it’s the "liquid gold" of the Mediterranean diet. But if you’re actually trying to track your macros or lose a few pounds, that casual pour might be the reason your weight isn't budging. Honestly, the calories in a tbsp of olive oil are higher than most people realize when they're just "eyeballing" it.
The math is pretty rigid here.
One tablespoon of olive oil contains roughly 119 to 120 calories. If you use two tablespoons to sauté your kale, you’ve just added 240 calories to a bowl of greens that originally only had 30. That is a massive energy density jump. It doesn't matter if it's "Extra Virgin," "Pure," or "Light"—the caloric load stays almost exactly the same because fat is fat when it comes to energy measurements.
Why the density matters for your waistline
Fat is the most energy-dense macronutrient we eat. While protein and carbs give you 4 calories per gram, fat gives you 9. Olive oil is 100% fat. There’s no fiber, no protein, and no water to bulk it out. It is pure, concentrated energy.
When people talk about the calories in a tbsp of olive oil, they often overlook the "creep." Think about it. You put a tablespoon in the pan. Then you drizzle another over the finished salmon. Maybe a little more on the salad. Suddenly, you've consumed 360 calories of oil alone. That’s equivalent to about three large bananas or five cups of sliced strawberries. It’s easy to eat, but it’s very hard to burn off if you aren't paying attention.
Dr. Simon Poole, a renowned expert on the Mediterranean diet, often points out that while the quality of the oil matters for heart health, the quantity matters for weight management. You can’t ignore the physics of energy balance just because the fat is "good."
The "Extra Virgin" myth regarding calories
Many people think that "Light" olive oil has fewer calories. It’s a trick of language.
In the world of olive oil, "light" refers to the flavor and color, not the calorie count. Refined olive oils are processed to remove the strong, peppery taste of the olives. This makes them great for high-heat frying, but they still pack the same 120 calories per tablespoon as the most expensive, hand-pressed Extra Virgin Olive Oil (EVOO) from a boutique farm in Tuscany.
EVOO is actually the superior choice, but not because it's lower in calories. It’s because of the polyphenols. These are bioactive compounds like oleocanthal and oleuropein. They fight inflammation. They protect your heart. If you’re going to spend your "calorie budget" on oil, spend it on the stuff that actually does something for your cells.

Does the brand change the calories in a tbsp of olive oil?
Not really. Whether you buy Kirkland Signature from Costco or a $50 bottle of California Olive Ranch, the fat profile is nearly identical. You’re looking at about 13.5 to 14 grams of total fat per tablespoon.
Most of that—around 73%—is monounsaturated fat, specifically oleic acid. Then you’ve got about 14% saturated fat and 11% polyunsaturated fat (omega-6 and omega-3).
- Monounsaturated Fat: 9.9 grams
- Saturated Fat: 1.9 grams
- Polyunsaturated Fat: 1.4 grams
This specific ratio is why olive oil is liquid at room temperature but gets cloudy and thick in the fridge. It’s a chemistry thing. But regardless of the fatty acid breakdown, the calories in a tbsp of olive oil remain anchored at that 120 mark.
The hidden danger of "The Drizzle"
Go to a fancy Italian restaurant. They bring out the bread basket and a small dish of olive oil. You dip. You chat. You dip again. A single "dip" can easily soak up half a tablespoon of oil. Over the course of a pre-dinner conversation, you might consume three or four tablespoons of oil without even touching your actual meal.
That’s 480 calories. Just from the oil.
I’ve seen clients wonder why they can’t lose weight while eating a "clean" diet. Often, it’s the olive oil. They’re cooking everything in it because they heard it was heart-healthy. It is! But your heart doesn’t care if those excess calories come from olive oil or a Snickers bar if they’re contributing to visceral fat gain.
Cooking temperatures and caloric stability
There is a weird rumor floating around the internet that heating olive oil changes its calorie count.
It doesn't.

What heating does do is potentially degrade the antioxidants. If you heat EVOO past its smoke point—which is usually around 375°F to 405°F (190°C to 207°C)—you start breaking down those precious polyphenols. You might even create some nasty polar compounds. But the calories in a tbsp of olive oil stay the same. The energy is still there; it just might come with a side of scorched flavor and fewer health benefits.
If you're doing high-heat roasting or searing, you might actually be better off using a refined olive oil or avocado oil, then finishing the dish with a raw drizzle of high-quality EVOO to keep the nutrients intact.
Real-world comparisons: Olive oil vs. others
How does olive oil stack up against other fats? It’s a common question.
Butter has about 102 calories per tablespoon. Wait—butter has fewer calories? Yes. That’s because butter contains a small amount of water and milk solids. Olive oil is pure fat. However, butter has significantly more saturated fat, which is where the heart health debate kicks in.
Coconut oil is another big one. It sits at about 117 calories per tablespoon. Very similar to olive oil. But again, the fatty acid profile is totally different, being mostly saturated.
Then you have the commercial "vegetable oils" (usually soybean or canola). These are almost identical in calories to olive oil. The reason we choose olive oil isn't to save calories; it's to get the micronutrients and the better fat ratio.
Measuring is the only way to be sure
If you're serious about your health, stop pouring straight from the bottle. Use a measuring spoon.
It sounds tedious. It feels "diet-y." But the difference between a "true" tablespoon and a "heavy pour" is often 100 calories. Do that three times a day, and you’ve added 300 calories to your intake. Over a week, that’s 2,100 calories—almost enough to stall weight loss for the average person entirely.

Use an oil mister if you want to coat a pan. A spray usually delivers about 5 to 10 calories per second of spraying. It’s a massive savings compared to the 120 calories in a tbsp of olive oil.
The satiety factor
One thing olive oil has going for it is satiety. Fat triggers the release of cholecystokinin (CCK) and peptide YY (PYY), hormones that tell your brain you’re full.
If you eat a salad with fat-free dressing, you’ll probably be hungry again in an hour. If you use a tablespoon of olive oil, the fat slows down gastric emptying. Your stomach holds onto that food longer. You feel satisfied. In this sense, those 120 calories are an "investment" in staying full so you don't go hunting for cookies later in the afternoon.
Actionable steps for managing your intake
Don't stop using olive oil. It’s legitimately one of the healthiest foods on the planet. But you have to respect its power.
First, buy a high-quality, dark-glass bottle of Extra Virgin Olive Oil to ensure you’re getting the polyphenols that justify the caloric cost. Look for a harvest date on the label.
Second, get a set of actual measuring spoons. Keep the tablespoon right next to your stove. For one week, measure every single drop you use. You’ll probably be shocked at how much you were actually using when you were just winging it.
Third, try "diluting" your oil in dressings. Use a mix of Dijon mustard, lemon juice, or balsamic vinegar with just a tiny bit of oil. The acidity and spice provide flavor so you don't need a half-cup of oil to make your salad taste good.
Finally, prioritize raw usage. Since the calories in a tbsp of olive oil are the same whether it's cooked or raw, use cheaper oils (like avocado or refined olive oil) for the high-heat frying where the flavor gets lost anyway. Save the expensive, high-calorie EVOO for drizzling over soup or dipping a small piece of sourdough. This way, you get the maximum sensory experience and the best health profile for your caloric buck.
Knowing the numbers isn't about restriction; it's about making an informed trade-off. 120 calories is a lot, but for the heart-protective benefits of a good olive oil, it’s often worth it—as long as you’re the one in control of the pour.
