The trend of adding coconut oil to coffee has stirred interest in the health and fitness communities, especially among individuals seeking weight loss or an energy boost. While some tout it as a miraculous weight loss solution, it's essential to explore the science-backed evidence and potential drawbacks before incorporating this practice into your daily routine.
Is It Safe and Beneficial?
Adding coconut oil to coffee is generally considered safe. Some proponents suggest it can increase the number of calories you burn throughout the day due to the ketone bodies produced by the liver after coconut oil consumption. Others believe that the caffeine in coffee acts as an appetite suppressant. Some people find that drinking coconut oil with coffee after a long day replenishes their energy levels.
Coconut oil contains lauric acid, a healthy fat with antibacterial properties that may boost the immune system. Caffeine, a brain stimulant, can increase attentiveness. Ketone bodies, produced from the metabolism of MCTs in coconut oil, have been studied for their potential to nourish brain cells in conditions like Alzheimer's disease, potentially improving symptoms.
The Science Behind Coconut Oil and Weight Loss
Health claims surrounding coconut oil for weight loss often stem from studies on medium-chain triglycerides (MCTs). Coconuts are a natural source of MCTs, but coconut oil also contains other types of fats. MCTs, such as capric and caprylic acid, found in coconut oil may promote weight loss by enhancing the body's metabolism and increasing satiety. These MCTs are rapidly metabolized due to their shorter carbon chains. Unlike long-chain triglycerides (LCTs), MCTs are transported directly to the liver, bypassing the lymphatic system, where they are quickly converted into energy and ketones.
Some believe that ketones are a more efficient energy source than glucose, the body's primary fuel. Because the body uses MCTs almost immediately, they may produce a thermogenic effect, enhancing the body's ability to burn fat. A meta-analysis in 2015 suggested that replacing LCTs with MCTs in the diet could lead to modest reductions in body weight, visceral fat, and total body fat.

However, it's crucial to differentiate between coconut oil and MCT oil. Coconut oil contains smaller quantities of MCTs, with around 50% of its fat content being lauric acid. While some consider lauric acid an MCT, it behaves more like an LCT in terms of absorption and metabolism. MCT oil typically contains only six to ten carbon atoms, while lauric acid contains 12.
Potential Benefits of Coconut Oil in Coffee
Metabolism Boost
The MCTs in coconut oil and the caffeine in coffee may work synergistically to speed up metabolism. This could potentially increase the number of calories burned throughout the day.
Increased Energy Levels
Coffee contains caffeine, which can help combat fatigue. Coconut oil provides MCTs, which are rapidly transported to the liver and used as a quick energy source.
Enhanced Satiety
Eating high-fat foods may contribute to higher levels of satiety, preventing overeating. Coconut oil may increase feelings of fullness and enhance appetite regulation by increasing stomach volume.
Improved Cholesterol Levels
Studies suggest that coconut oil consumption may increase high-density lipoprotein (HDL) cholesterol levels, often referred to as "good cholesterol," without affecting low-density lipoprotein (LDL) cholesterol levels ("bad cholesterol"). HDL cholesterol is known to protect against heart disease.

Potential Cognitive Benefits
Many people report feeling more focused and mentally sharp after drinking coffee with coconut oil. MCTs have been studied for their potential benefits to brain health, with some research suggesting they can improve memory and protect against neurodegenerative diseases like Alzheimer's. Ketone bodies help nourish the brain cells in this condition, which can help improve symptoms.
Possible Benefits for Ketosis
For individuals following a ketogenic diet, adding coconut oil to coffee may help them reach or maintain ketosis. Coconut oil is rich in MCTs, which are easily converted into ketone bodies in the liver. Lauric acid, a type of MCT found in coconut oil, may produce ketones at a slower but more sustained rate.
Potential Drawbacks and Considerations
High Calorie Content
Coconut oil is fat and high in calories, with approximately 121 calories per tablespoon (14 grams). Consuming two tablespoons of coconut oil in coffee adds an extra 242 calories to your daily intake. While the combined effect of coconut oil and coffee may slightly boost metabolism, it's more likely to lead to weight gain if you don't account for the added calories.
Saturated Fat Content
Coconut oil consists primarily of saturated fats. While once demonized, the view on saturated fats is evolving. The American Heart Association recommends limiting saturated fat intake to no more than 13 grams per day, which is approximately one tablespoon of coconut oil. It's generally a good idea to have your cholesterol and other blood levels checked every six months or so.
Digestive Issues
If you've never had coffee with coconut oil before, start with a small amount, such as half a teaspoon, to avoid potential digestive issues. Excess intake of coffee and coconut oil can cause stomach pain or tremors due to the caffeine content.

Not a Replacement for a Balanced Breakfast
Many people, particularly those trying to lose weight, substitute coconut oil coffee for breakfast. While convenient, this practice may lead to missing out on essential nutrients obtained from a more balanced breakfast.
Potential Interactions
Coconut oil in coffee should not be consumed with other caffeine sources, such as green tea, chocolate, or yerba mate, as this could lead to excessive caffeine intake. Coffee with coconut oil is not recommended for children under 12 years old.
Inconsistent Research Findings
Studies on the effects of coconut oil on weight have produced inconsistent and contradictory results. More research is needed to fully understand its impact on weight loss.
Concerns for Certain Medical Conditions
Certain medical conditions, such as gallbladder issues or pancreatitis, may require limiting fat intake. In such cases, adding coconut oil to coffee may not be advisable.
How to Incorporate Coconut Oil into Coffee
If you want to try coconut oil in your coffee, start with one tablespoon (14 grams) of cold-pressed virgin coconut oil per cup of hot coffee. Stir thoroughly to ensure the oil incorporates well. Alternatively, blend the oil with coffee in a blender to create a smooth, tropical-style beverage. Gradually increase the amount to suit your needs, but avoid adding too much too quickly, as it may cause nausea and laxative-like symptoms.
The Importance of a Balanced Lifestyle
Adding coconut oil to coffee should be viewed as part of a broader approach to health and well-being. To achieve weight loss and prevent disease, it's essential to maintain a healthy diet, exercise regularly, and prioritize overall lifestyle choices. Coconut oil is much more effective when you use it to replace less healthy fats in your diet, such as those from processed foods, rather than on top of the fats you're currently consuming.
