What is MCT Oil?

MCT (medium-chain triglycerides) oil is made out of a type of fat found in certain dairy products and oils like coconut and palm oil.

MCT molecules are smaller than those in most of the fats you eat and, unlike other fats, they go straight from the gut to the liver. From here, they are used as a source of energy or turned into ketones.

To see how MCT oil can be used for weight loss, it’s worth understanding the precious moment when our bodies enter the weight loss stage called ketosis.

When digesting food, carbs in the food break down into a type of sugar called glucose. Usually, this would be the primary fuel in the body to generate energy. However, when there are no glucose stores left in the body, it enters a process called ketosis. It means your body is starting to burn fat to make compounds called ketones, which it can use for fuel. 

There are two ways to get your body into ketosis and start burning fat.

One way would be to stop eating until the body uses all the glucose stores and starts burning ketones a.k.a. fat instead. This can be done by practicing intermittent fasting.

Another way to get into ketosis is by following the keto diet. It is a diet low in carbs, high in fats and moderate in protein. MCT oil is an excellent supplement or the best MCT oil for keto diet as it’s pure fat; therefore, it won’t kick you out of ketosis.
