What is the Difference Between MCT and LCT?

🆚 Go to Comparative Table 🆚

The main difference between medium-chain triglycerides (MCT) and long-chain triglycerides (LCT) lies in their chain length, metabolism, and health benefits. Here are the key differences:

  1. Chain Length: MCTs are shorter in length than LCTs, containing 6-12 carbon fatty acids, while LCTs have fatty acids with more than 12 carbons.
  2. Metabolism: MCTs are rapidly metabolized by the liver, providing a quick source of energy and being less likely to be stored as body fat. LCTs, on the other hand, are metabolized more slowly and are stored in the body's fat cells for later use as energy.
  3. Caloric Content: MCTs provide fewer calories per gram than LCTs, with 8.3 calories per gram for MCTs and 9.2 calories per gram for LCTs.
  4. Health Benefits: Plant-based LCTs, such as those found in olive oil, avocado, and nuts, are typically unsaturated fats and have many health benefits when consumed in moderation. They can help lower cholesterol levels, reduce inflammation, and improve heart health. Some research suggests that plant-based LCTs are less likely to be stored as fat.
  5. Food Sources: MCTs are found in coconut oil, palm oil, and dairy products, while LCTs are found in many common foods such as butter, beef, pork, and other animal products.

In summary, MCTs are shorter in length, provide fewer calories, and are more rapidly metabolized than LCTs. MCTs can be found in coconut oil, palm oil, and dairy products, while LCTs are found in various animal products and plant-based oils. Plant-based LCTs offer numerous health benefits when consumed in moderation.

Comparative Table: MCT vs LCT

Medium-chain triglycerides (MCT) and long-chain triglycerides (LCT) are derivatives of triglycerides, and they differ in the length of their carbon chains and their digestion and absorption processes. Here is a table summarizing the differences between MCT and LCT:

Property Medium-Chain Triglycerides (MCT) Long-Chain Triglycerides (LCT)
Carbon Chain Length 6 - 12 carbons > 12 carbons
Calories per Gram 8.3 calories 9.2 calories
Digestion and Absorption MCTs are absorbed more easily and enter the bloodstream quickly, bypassing the lymphatic system LCTs are absorbed more slowly and enter the lymphatic system before reaching the bloodstream
Energy Expenditure MCT consumption has been shown to increase energy expenditure (EE) and lead to greater losses of adipose tissue in animals LCT consumption does not have the same impact on energy expenditure as MCTs

MCTs are typically found in coconut oil, palm oil, and butter, while LCTs are found in most other fats and oils, including vegetable oils, dairy products, and meat. The shorter chain length of MCTs allows them to be absorbed more easily and quickly, providing a source of energy that is more readily available than LCTs.
