The way people carefully weigh chicken breasts and count almonds, then turn around and carelessly pour a generous glug of olive oil into a pan is almost comical. It vanishes into the heat. It subtly coats the food. And no one records it. Most people are unaware of how much calorie-intensive work that little, casual moment is doing when repeated a few times a week.
There are about 120 calories in one tablespoon of olive oil. By itself, it’s not a concerning figure. However, the math has a way of quietly compounding. You only need to add roughly 71 calories per day to reach 500 extra calories over the course of seven days. That amounts to slightly more than two teaspoons of olive oil, which is so little that it would hardly cover the bottom of a teaspoon, much less make a significant difference in any meal.
It’s worth taking a moment to consider that. Five hundred calories per week seems like a lot of work. Another portion of pasta. An extra granola handful. A habit of snacking after dinner. However, two teaspoons of olive oil? That’s the amount of rice that remains on a spoon after stirring. The grilled chicken appears more appetizing when it is lightly brushed. Almost out of habit, it’s the swirl dropped into a bowl of soup.

The fact that olive oil adds almost no volume or texture to food is what makes it such a unique source of calories. Oil blends into everything it comes into contact with, unlike when you add an extra scoop of rice or a side of bread. It vanishes. The food is identical in terms of appearance, texture, and weight in your palm. However, there has been no discernible change in the calorie content, sometimes in a significant way.
This invisibility is reciprocal. Olive oil is actually one of the more useful tools for someone attempting to gain weight. You don’t have to force down a protein shake, eat more food, or sit through a longer meal. When a teaspoon is added to morning eggs, another is drizzled over afternoon grain, and an evening protein is lightly brushed on, the week ends with 500 extra calories without any meals feeling any different. If you’ve had trouble eating more, that is actually helpful.
However, the same feature becomes a liability for someone who is closely monitoring their caloric intake. Almost everyone pours oil into a pan without measuring, which can easily add 100 to 200 calories to a meal without being aware that they are eating. It’s not exactly dishonesty in logging. The brain does not process oil in the same manner as it does food. The salmon is visible to you. The two tablespoons of oil it cooked in are barely noticeable.
Without getting bogged down in the math of calories, there is also a more comprehensive nutritional tale here. There is no empty fat in olive oil. It contains oleocanthal, which has been shown to have anti-inflammatory properties, polyphenols, and a fat profile that is primarily monounsaturated. A strict calorie tracker would be horrified by the liberal use of olive oil that forms part of the Mediterranean diet that researchers keep coming back to. The conflict between olive oil as a calorie-dense liquid and olive oil as a health benefit is real and doesn’t entirely go away.
Practically speaking, it does imply that olive oil is one of those uncommon ingredients where awareness is more important than restriction. A simple and efficient way to reduce your weekly intake by 500 calories is to add two teaspoons per day to the meals you already prepare. Depending on the direction you’re trying to go, that could be a problem or a good thing. In either case, the work is being done by the oil. The majority simply aren’t paying attention.
