Does Mct Oil Help With Ketosis

Does MCT Oil Help with Ketosis?

When it comes to the ketogenic diet, many people are looking for ways to enhance their results and accelerate the process of entering ketosis. One popular supplement that is often recommended is MCT oil. But does MCT oil really help with ketosis? In this article, we will explore the science behind MCT oil and its potential benefits for those following a ketogenic diet.

Understanding Ketosis

Before diving into the role of MCT oil in ketosis, it is important to understand what ketosis is. Ketosis is a metabolic state in which the body switches from using glucose as its primary fuel source to using ketones, which are produced from stored fat. This shift occurs when carbohydrate intake is significantly reduced, forcing the body to burn fat for energy.

What is MCT Oil?

MCT stands for medium-chain triglycerides, which are a type of fat found in certain foods and oils. Unlike long-chain triglycerides (LCTs), which are the predominant type of fat in our diet, MCTs are easily digested and rapidly absorbed by the body. This makes them a quick and efficient source of energy.

MCT oil is a concentrated form of MCTs extracted from coconut oil or palm kernel oil. It is a popular supplement among those following a ketogenic diet due to its potential to increase ketone production and support the transition into ketosis.

The Role of MCT Oil in Ketosis

MCT oil has several properties that make it beneficial for individuals on a ketogenic diet:

  • Rapidly Converted into Ketones: MCTs are quickly broken down in the liver and converted into ketones, which can be used as an immediate source of energy. This can help individuals reach and maintain a state of ketosis more efficiently.
  • Increased Ketone Production: Consuming MCT oil has been shown to increase blood ketone levels, even in the absence of carbohydrate restriction. This can be particularly useful for individuals who are struggling to enter ketosis or want to boost their ketone levels for enhanced fat burning.
  • Appetite Suppression: MCT oil has been found to increase feelings of fullness and reduce appetite, which can be beneficial for those following a calorie-restricted ketogenic diet for weight loss.
  • Enhanced Mental Clarity: Ketones produced from MCTs can cross the blood-brain barrier and serve as an alternative fuel source for the brain. This has been associated with improved cognitive function and mental clarity.

Scientific Evidence

Several studies have investigated the effects of MCT oil on ketosis and overall health. One study published in the journal Metabolism found that consuming MCT oil led to higher levels of ketones compared to LCTs, even when carbohydrate intake was not restricted. Another study published in the American Journal of Clinical Nutrition showed that MCT oil increased fat oxidation and energy expenditure, suggesting a potential role in weight management.

Furthermore, a review of 13 studies published in the journal Obesity Reviews concluded that MCT oil can increase ketone production and promote fat loss when included in a ketogenic diet. However, it is important to note that individual responses may vary, and more research is needed to fully understand the long-term effects of MCT oil supplementation.


1. Can MCT oil be consumed on its own?

Yes, MCT oil can be consumed on its own or added to various foods and beverages. It has a neutral taste and can be easily incorporated into your daily routine.

2. How much MCT oil should I consume?

The recommended dosage of MCT oil varies depending on individual needs and tolerance. It is generally recommended to start with a small amount, such as 1 teaspoon, and gradually increase the dosage to avoid digestive discomfort.

3. Can MCT oil help with weight loss?

MCT oil has been shown to increase feelings of fullness and reduce appetite, which can support weight loss efforts. However, it is important to combine MCT oil supplementation with a balanced diet and regular exercise for optimal results.

4. Are there any side effects of consuming MCT oil?

While MCT oil is generally well-tolerated, some individuals may experience digestive issues such as diarrhea or stomach cramps when consuming large amounts. Starting with a small dosage and gradually increasing it can help minimize these side effects.

5. Can MCT oil be used by individuals not following a ketogenic diet?

Yes, MCT oil can be beneficial for individuals not following a ketogenic diet as well. Its quick conversion into ketones provides a readily available source of energy, making it a popular supplement among athletes and those seeking sustained energy levels.

6. Can MCT oil be used for cooking?

Yes, MCT oil has a high smoke point and is stable at high temperatures, making it suitable for cooking and baking. However, it is important to note that excessive heat can degrade the quality of the oil, so it is best to use it for low to medium heat cooking.


MCT oil can be a valuable tool for individuals following a ketogenic diet. Its ability to increase ketone production, support fat burning, and enhance mental clarity make it a popular supplement among those seeking to optimize their results. However, it is important to remember that MCT oil is not a magic solution and should be used in conjunction with a well-rounded ketogenic diet and lifestyle. As with any dietary supplement, it is always recommended to consult with a healthcare professional before incorporating MCT oil into your routine.
