Will olive oil raise cholesterol?
Will a daily spoon of olive oil raise your cholesterol? The short answer is no — its fats are the good kind. But olive oil is still pure fat, calorie-dense and nutritionally narrow, so the real question is not whether it is healthy but how much, and instead of what.
Start with the reassuring part. Like all dietary fats, olive oil is a mix of saturated, polyunsaturated and monounsaturated fatty acids — but it is dominated by monounsaturated fat, around three-quarters of the total, mostly oleic acid. Monounsaturated fat is associated with lowering LDL, the so-called bad cholesterol, without lowering HDL, the good kind, especially when it replaces saturated fat like butter. As fats go, olive oil is one of the better choices you can put on your plate.
But it is still fat
Here is the part the enthusiasts skip. Olive oil, like every oil, is essentially pure fat — about 14 grams of fat and roughly 120 calories in a single tablespoon. Two spoonfuls a day added to your meals, rather than replacing something else, is around 240 extra calories daily, and over time surplus calories become weight regardless of how heart-friendly the source is. Swapping olive oil for butter or a lesser oil is a genuine upgrade ; simply pouring more of it on top of everything is not.
| Total fat | ~14 g per tablespoon |
|---|---|
| Calories | ~120 per tablespoon |
| Monounsaturated fat | ~73% of the oil (mainly oleic acid) |
| Effect on cholesterol | May lower LDL, especially replacing saturated fat |
| Micronutrients | Some vitamin E and vitamin K; little else |
| Polyphenols | Antioxidants in extra virgin, refined out of lighter grades |
| Best role | A replacement fat, used in moderation |
Beware the ‘oil diet’ framing
The original worry that prompts this question is usually a fad: a plan telling you to swallow spoonfuls of oil before meals for some special effect. Be sceptical. Dietitians classify these as fad diets — the exaggerated belief that a single food, taken a certain way, delivers outsized health benefits or quick weight loss. Olive oil is a fine fat, not a supplement to be dosed. It also offers little beyond fat and a modest amount of vitamin E and K ; for the same 120 calories you could eat a good deal of fruit, vegetables or yoghurt and get far more nutrition.
Sensible takeaways
- Olive oil’s fats are heart-friendly and unlikely to raise your cholesterol.
- It is still calorie-dense — around 120 calories a tablespoon — so portion matters.
- The benefit comes from replacing butter and lesser oils, not from adding oil on top.
- Treat ‘drink oil before meals’ plans as fad diets, and be wary.
- Extra virgin carries the antioxidants; refined ‘light’ grades have them stripped out.

Olive oil and cholesterol: common questions
Will olive oil raise my cholesterol?
It is unlikely to. Olive oil is mostly monounsaturated fat, which is associated with lower LDL cholesterol, particularly when it replaces saturated fat. This is general information, not medical advice.
Is olive oil low in calories?
No. It is essentially pure fat, about 120 calories and 14 grams of fat per tablespoon — the same as other oils.
Does light olive oil have fewer calories?
No. ‘Light’ refers to colour and flavour, not calories. All olive oil has roughly the same energy and fat content.
Should I swallow spoonfuls of olive oil for my health?
There is no need. Diets built on dosing oil are fad diets. Use olive oil as a replacement fat in a balanced diet rather than as a supplement.
How much olive oil is sensible?
Enough to replace less healthy fats, used in moderation. Adding extra oil on top of your usual diet just adds calories.
Olive oil’s health halo is mostly deserved, but it has quietly become an excuse to drown everything in it. The benefit was always comparative — good instead of butter, not good on top of butter. A tablespoon is 120 calories whether it is the finest extra virgin or a cheap refined oil, and no fat is a health supplement to be spooned down neat. Use a good oil generously where it replaces something worse, keep an eye on the total, and ignore anyone selling it as a cure. This is general information, not medical advice.
