What's the Difference?

LCT (Long Chain Triglycerides) and MCT (Medium Chain Triglycerides) are two types of dietary fats that differ in their chemical structure and metabolism in the body. LCTs are composed of long-chain fatty acids, typically containing 13 to 21 carbon atoms, while MCTs consist of medium-chain fatty acids with 6 to 12 carbon atoms. Due to their shorter chain length, MCTs are more easily digested and absorbed by the body, providing a quick source of energy. On the other hand, LCTs require more time and energy for digestion and absorption. MCTs are also less likely to be stored as body fat compared to LCTs. While both types of fats have their own benefits and uses, MCTs are often preferred for their rapid energy release and potential weight management properties.

Further Detail


When it comes to dietary fats, there are various types available, each with its own unique characteristics and effects on the body. Two popular types of fats that have gained attention in recent years are Long-Chain Triglycerides (LCT) and Medium-Chain Triglycerides (MCT). While both LCT and MCT are forms of saturated fats, they differ in their chemical structure and how they are metabolized by the body. In this article, we will explore the attributes of LCT and MCT, highlighting their differences and potential benefits.

Chemical Structure

LCT and MCT differ in their chemical structure, which ultimately affects how they are processed by the body. LCTs are composed of long-chain fatty acids, typically containing 13 to 21 carbon atoms. On the other hand, MCTs consist of medium-chain fatty acids, which have 6 to 12 carbon atoms. This structural difference impacts their digestion, absorption, and utilization within the body.

Digestion and Absorption

Due to their distinct chain lengths, LCTs and MCTs undergo different processes during digestion and absorption. LCTs require the action of pancreatic enzymes and bile acids to break them down into smaller components before they can be absorbed by the small intestine. This process is relatively slow and requires more energy.

In contrast, MCTs are rapidly digested and absorbed without the need for pancreatic enzymes or bile acids. They are transported directly to the liver via the portal vein, where they are quickly converted into energy or ketones. This efficient digestion and absorption make MCTs an attractive option for individuals seeking a readily available energy source.

Metabolism and Energy Production

Once absorbed, LCTs and MCTs are metabolized differently by the body, leading to variations in energy production. LCTs are primarily stored in adipose tissue as triglycerides, serving as a long-term energy reserve. They are slowly broken down and utilized by the body during periods of energy deficit.

MCTs, on the other hand, are rapidly metabolized and converted into energy. They are transported directly to the mitochondria, the powerhouse of the cells, where they undergo beta-oxidation and produce ATP (adenosine triphosphate), the body's main energy currency. This quick conversion into energy makes MCTs a valuable option for individuals looking for an immediate energy boost.

Health Benefits

Both LCTs and MCTs offer potential health benefits, although their effects may vary. LCTs, being the predominant form of dietary fats, provide essential fatty acids and fat-soluble vitamins. They also contribute to satiety, helping individuals feel fuller for longer periods.

MCTs, on the other hand, have gained attention for their unique properties and potential health benefits. Due to their rapid metabolism and conversion into ketones, MCTs have been studied for their potential role in weight management. Some research suggests that MCTs may increase energy expenditure and fat oxidation, potentially aiding in weight loss efforts.

Moreover, MCTs have been shown to have antimicrobial and antifungal properties, which may support gut health and help combat certain infections. Additionally, MCTs are often used in medical nutrition therapy for individuals with malabsorption disorders, as they are easier to digest and absorb compared to LCTs.

Sources of LCT and MCT

LCTs are commonly found in various food sources, including animal fats, such as butter, lard, and fatty cuts of meat, as well as plant-based oils like olive oil, coconut oil, and soybean oil. These sources provide a mix of saturated and unsaturated fats, with LCTs being the predominant form.

MCTs, on the other hand, are naturally present in smaller amounts in certain foods, such as coconut oil, palm kernel oil, and dairy products. However, to obtain higher concentrations of MCTs, refined MCT oils are often used as a dietary supplement or ingredient in various products.


In summary, LCTs and MCTs are two types of saturated fats that differ in their chemical structure, digestion, absorption, metabolism, and potential health benefits. LCTs are composed of long-chain fatty acids and are slowly digested and metabolized, serving as a long-term energy source. MCTs, on the other hand, consist of medium-chain fatty acids and are rapidly digested, absorbed, and converted into energy, making them a readily available fuel source.

While both LCTs and MCTs have their own unique attributes, it is important to note that moderation and balance are key when it comes to dietary fat intake. Incorporating a variety of fats from different sources, including LCTs and MCTs, can contribute to a well-rounded and balanced diet. As always, consulting with a healthcare professional or registered dietitian is recommended to determine the most suitable dietary approach based on individual needs and goals.
