Looking to lose some weight? Being on the ketogenic diet can certainly be one way to get there. Following a keto-friendly diet is a popular diet that is usually high in fat, moderate in protein, and very low in carbohydrates.    

Because carbohydrates are the main source of energy for the brain and body, having a low amount of carbs means you need to get your energy from a different source. As your body becomes depleted in carbs on a keto diet, your body begins to burn fat for energy, thus producing ketones. This process is known as a state of ketosis[1]

When on the ketogenic diet, the goal is to get to a state of ketosis where you produce ketone bodies from the breakdown of fat. These ketone bodies can then be used for energy. Using MCT oil is another way of getting fat into your body that is quickly absorbed for energy use. 

MCT oil is a popular supplement that stands for medium-chain triglycerides. It is a type of fat that is easily digested and used for energy while on a keto diet. Many keto proponents consider it a healthy fat for this reason, even though it is sourced from saturated fat-rich coconut oil.

Using MCT oil as an energy source can sound funny in that using fat to lose fat may not make sense. But it’s about the type of fat and how it breaks down in the body. MCT oil is a particular type of fat seen to be efficiently utilized for energy that may help burn fat.

What is MCT Oil?

There are two types of fats – medium-chain (MCT) and long-chain triglycerides (LCT), classified based on their chemical structure. 

MCT may potentially help with weight management, making them useful to include while on a keto-friendly diet. MCT oil is usually found in four different types of forms, such as:

  • Caproic acid (C6)
  • Caprylic acid (C8)
  • Capric acid (C10)
  • Lauric acid (C12)

The best MCT oils that are most commonly used in MCT oil supplements are capric acid and caprylic acid.  

MCT oil is typically derived from coconut oil, palm oil, and dairy products[2] like whole milk and butter. 

While on a keto diet, the number of carbs on the diet does not provide the body with enough energy, forcing the body to burn fat for energy instead. But in order to provide energy to the brain,  you need a type of fat that can get through the blood-brain barrier. MCT oils contain small fat molecules that can enter the blood-brain barrier more easily to help provide energy.

Who Should Take MCT Oil?

There are many possible health benefits to taking MCT oil. It can boost energy, improve mental clarity, brain function, and brain health, promote energy, support weight loss, and manage some health conditions[3]

Any healthy adult that is looking for such benefits can take a high-quality MCT oil as part of their daily fat intake of the day, not in addition. Consuming too much fat can contribute to fat storage, no matter how healthy the fat may be. Learn about the best MCT oil for weight loss and ketosis.

Benefits of MCT Oil

MCT oil is commonly used while on a keto diet as an energy source, but it does have other possible benefits. It could potentially promote healthy weight management or weight loss[6]. It could be a good source of quick energy; the body easily absorbs the medium chain triglycerides making them readily available for energy use[7].

In athletes, MCT oil can help in the reduction of lactate build-up in the muscle as well as up the use of fat for energy[8]

There is the possibility that MCT oil can help with managing epilepsy[9], Alzheimer’s disease[10], or autism[11].

There is also research that shows MCT oils may provide antifungal and antimicrobial[12] benefits, and may help reduce harmful bacterial growth

Because MCT oil has been associated with fat loss, there is a possibility that it can help control disease in the cardiovascular system. MCT oils can have some effects on blood pressure, high cholesterol, inflammation, and overall body mass index[2].

If you have diabetes, MCT oils can also have a positive effect. In its role in reducing body fat, it may also help support healthy insulin levels and aid in managing diabetes[13]

Potential Side Effects of MCT Oil

MCT oils have some great benefits, but there are some drawbacks. The first and most important one is it’s high in calories. If you are just taking it without a balanced diet and exercise, it may  potentially contribute to fat accumulation[14] in the liver and excess calorie intake 

Some MCT oil users have reported stomach upset after consumption; therefore, most manufacturers will instruct to start with small dosages until tolerated. 

How to Choose The Best MCT Oils?

When choosing MCT oil products for weight management, you’ll want to seek a high-quality MCT oil. To be considered high quality,  the source of MCT oils should be organic, non-GMO coconuts and they should be third-party tested to ensure it meets quality and potency standards. If you are vegan, finding a vegan-certified MCT oil may also be part of your criteria. 

Another source of medium-chain triglycerides is derived from palm oil. However, most people now avoid products made of palm oil as it contributes to deforestation and loss of habitat for animals, and can be an issue for environmental sustainability. 

Frequently Asked Questions

How is MCT oil produced?

MCT is produced via a process called fractionation[15]. This process separates the different types of fats from long-chain and medium-chain triglycerides and retains specific fatty acids as part of the product.

How much MCT oil should you take on a daily basis?

There is no standard dosage; you will need to follow the manufacturer’s recommendation.

How to naturally include MCTs in your diet?

You can add them to coffee, smoothies, and protein drinks. Some brands can be added to your food.

The most commonly reported side effect is an upset stomach.  Some manufacturers will recommend starting out with a smaller dose for this reason until tolerated. 

Does MCT oil work for weight loss?

MCT oil is often used to help with energy production, but there are some studies that say that it may benefit weight loss or weight management[16]. More research is still warranted in regards to MCT’s role in weight management. 

What are the other benefits of MCT oils?

Other possible benefits of MCT oil are its role in supporting energy, mental clarity and focus, and weight management.

Can MCT oil provide energy while on a ketogenic diet?

Yes, the medium chain triglycerides are smaller chains that can quickly be absorbed by the body and used as energy.
