Saturated fat from coconut oil raises LDL (“bad”) cholesterol, but its overall effect on heart disease risk is more nuanced than a simple yes or no. Compared to other saturated fats like butter, coconut oil behaves differently in the body, largely because of its unusual fatty acid profile. It’s not a health food, but it’s not the worst fat you could cook with either.
What Makes Coconut Oil Different From Other Saturated Fats
About 82% of coconut oil is saturated fat, which is higher than butter (63%) or even lard (39%). But the type of saturated fat matters. Coconut oil is roughly 46 to 54% lauric acid, a 12-carbon fatty acid that the body processes differently from the longer-chain saturated fats found in red meat and dairy. It also contains 5 to 10% caprylic acid and 5 to 8% capric acid, both medium-chain fatty acids that are absorbed and metabolized more quickly than typical dietary fats.
Lauric acid does raise total cholesterol, but a large portion of that increase lands on HDL cholesterol, the protective kind. A meta-analysis of 60 controlled trials found that oils rich in lauric acid actually decreased the ratio of total cholesterol to HDL cholesterol, a ratio many cardiologists consider more meaningful than LDL alone. By contrast, the saturated fats most common in butter and meat (myristic and palmitic acid) had little effect on that ratio.
How Coconut Oil Affects Your Cholesterol
A systematic review published in Circulation pooled data from 16 clinical trials and found that coconut oil raised LDL cholesterol by about 10.5 mg/dL compared to unsaturated vegetable oils like soybean or sunflower oil. At the same time, it raised HDL cholesterol by about 4 mg/dL. So coconut oil does push LDL higher when you compare it to oils like canola or olive oil, but it also gives HDL a boost.
The comparison to butter tells a more favorable story for coconut oil. A randomized trial published in BMJ Open assigned healthy adults to consume 50 grams daily of either extra virgin coconut oil, butter, or extra virgin olive oil for four weeks. Butter raised LDL significantly more than both coconut oil and olive oil. Coconut oil, surprisingly, did not raise LDL compared to olive oil. It also raised HDL more than both butter and olive oil, and it lowered C-reactive protein (a marker of inflammation) compared to olive oil.
In that same trial, the ratio of total cholesterol to HDL cholesterol, a key predictor of heart risk, was no different between coconut oil and olive oil. Butter performed worse on that measure than both.
Coconut Oil vs. Olive Oil and Other Cooking Fats
If you’re choosing between coconut oil and butter, coconut oil is the better option for your blood lipids. If you’re choosing between coconut oil and olive oil, the cholesterol picture is roughly similar in short-term trials, though olive oil has decades of epidemiological evidence supporting its role in heart-healthy diets like the Mediterranean pattern. Coconut oil lacks that long-term track record.
Compared to polyunsaturated vegetable oils (soybean, sunflower, corn), coconut oil consistently raises LDL more. These oils actively lower LDL, which is why most dietary guidelines recommend them as your primary cooking fat. The American Heart Association’s position is that coconut oil should not be used as a regular cooking oil, though it can be used sparingly for flavor or texture. Their recommendation is to replace it with unsaturated vegetable oils, particularly those rich in polyunsaturated fat, for everyday cooking.
The Metabolism and Weight Loss Claims
One of the most popular claims about coconut oil is that its medium-chain fatty acids boost your metabolism and help burn fat. The logic is that medium-chain triglycerides (MCTs) are sent directly to the liver for energy rather than stored as body fat, increasing calorie burn.
There’s a problem with applying this to coconut oil specifically. Pure MCT oil (concentrated caprylic and capric acid) does modestly increase energy expenditure in some studies. But coconut oil is not MCT oil. Its dominant fatty acid, lauric acid, behaves more like a long-chain fat in terms of digestion and absorption. A randomized, double-blind crossover trial comparing a coconut oil-rich meal to a corn oil meal found no difference in resting energy expenditure, no difference in the thermic effect of food (calories burned during digestion), and no difference in hunger, satiety, or how much participants wanted to eat afterward. The researchers had expected coconut oil to enhance satiety and reduce appetite. It did neither.
Coconut Oil Holds Up Well for Cooking
Where coconut oil does have a genuine advantage is heat stability. When oils are heated repeatedly, polyunsaturated fats break down and form oxidation byproducts. In a study that measured oxidation after 80 rounds of frying at 180°C (356°F), refined coconut oil produced the fewest harmful breakdown products of all oils tested, including soybean oil and palm olein. Soybean oil showed the highest levels of oxidation markers, while coconut oil barely changed. This makes coconut oil a reasonable choice for high-heat cooking or deep frying, even if it’s not the healthiest option at room temperature.
Virgin coconut oil has a smoke point around 177°C (350°F), and refined coconut oil sits higher at roughly 204°C (400°F). Both are stable enough for sautéing and baking, and the refined version works for most frying applications.
Practical Takeaway
Coconut oil’s saturated fat is not as harmful as the saturated fat in butter, but it’s not as beneficial as the unsaturated fat in olive oil or canola oil for everyday use. If you enjoy the flavor of coconut oil in certain dishes, using it occasionally in moderate amounts is unlikely to meaningfully worsen your cardiovascular risk, particularly if the rest of your diet relies on unsaturated fats. If you’re deep frying, its oxidative stability gives it a real functional advantage. But treating it as your default cooking oil, or consuming it by the tablespoon for supposed metabolic benefits, isn’t supported by the evidence.
