Medium-chain triglycerides, also called MCTs, are fats that give quick energy. Your body absorbs them faster than most other oils. They are mainly found in coconut oil and palm kernel oil. MCTs are popular in keto diets, workouts, and weight loss because they give energy without being stored as body fat like other fats.
What Exactly Are Medium-Chain Triglycerides ?
Fats are made of chains of carbon atoms.
Short chains digest very fast.
Long chains digest slowly.
MCTs are in the middle and digest quickly.
MCTs contain fatty acids with 6 to 12 carbon atoms, including caproic (C6), caprylic (C8), capric (C10), and lauric (C12) acids.
Unlike long-chain triglycerides (LCTs) found in olive oil or avocados, MCTs do not need bile to digest. They go straight from the gut to the liver, where they are turned into energy or ketones immediately. This fast process helps prevent energy crashes.
Scientists discovered the benefits of MCTs in the 1950s while processing coconut oil and noticed these fats worked differently from regular fats.
Medium-Chain Triglycerides Foods and Examples
You can get MCTs from common foods.
Coconut oil is the richest source, with about 55–60% MCTs. Many people add it to curries, coffee, or smoothies.
Butter and ghee contain around 7–9% MCTs and are often used in coffee or cooking vegetables. Whole cow’s milk and goat cheese provide 10–15% MCTs, while palm kernel oil is similar to coconut oil with 50%+ MCTs, often used in baking.
Coconut meat provides lauric acid and works well as a snack.
Full-fat yogurt, especially Greek yogurt, contains more MCTs.
Hard cheeses like cheddar contain small but steady amounts of MCTs.
Pure MCT oil is a refined product made from coconut oil. It has no color or taste and usually contains C8 and C10 fats.
MCT Foods Examples
| MCT Foods | Approx. MCT % | Best Uses |
| Coconut Oil | 55–60% | Cooking, coffee, skin |
| Butter/Ghee | 8–9% | Baking, spreads |
| Goat Milk | 15% | Smoothies, cheese |
| Palm Kernel Oil | 54% | Desserts, soaps |
These foods allow you to get MCTs naturally without supplements.
Medium-Chain Triglycerides Benefits
MCTs help improve overall health in many ways.
They increase energy burning by 5–12% compared to other fats, even while resting. Athletes benefit because MCTs fuel muscles without lowering glycogen levels. MCTs also support brain health by producing ketones that improve focus.
Gut health may improve because MCTs support good bacteria and reduce inflammation.
They help with weight control by increasing fullness hormones like PYY, which reduces overeating.
Heart health studies show MCTs have neutral effects on cholesterol.
MCT Foods for Weight Loss
MCT-rich foods support healthy weight loss.
Studies show 2 tablespoons of coconut oil per day can reduce waist size by increasing fat burning without increasing hunger. Butter can replace high-carb spreads in low-carb diets. Goat milk yogurt helps reduce cravings more than low-fat dairy because it keeps you full longer.
Breakfast ideas include eggs cooked in coconut oil.
Cheese cubes work well as energy-boosting snacks.
Goat milk blended with berries makes a low-calorie shake.
These foods help control blood sugar and reduce calorie intake naturally.
How to Use MCT Oil for Weight Loss
Start with 1 teaspoon of MCT oil in coffee. Slowly increase to 1–2 tablespoons per day, split between meals. This helps avoid stomach problems.
MCT oil works well in protein shakes before workouts and helps burn fat during cardio. It can replace salad dressings or be used for stir-frying at medium heat. When used with intermittent fasting, 15 ml during fasting helps control hunger.
Many people lose 1–2 pounds per week when MCT oil is combined with a calorie deficit. MCT oil should not be used for deep frying.
Where Do MCTs Hide in Your Food ?
MCTs are found naturally in foods.
Coconut oil contains 55–60% MCTs, mainly lauric acid.
Palm kernel oil contains 54% MCTs.
Butter and whole milk contain 8–9% MCTs.
Raw coconut meat and goat milk contain smaller amounts.
Food Source and MCT Content
| Food Source | MCT Content (% of total fat) | Key MCT Types |
| Coconut Oil | 55–60% | Lauric (C12), Caprylic (C8) |
| Palm Kernel Oil | 54% | Lauric (C12), Capric (C10) |
| Butter | 8% | Caprylic, Capric |
| Whole Milk | 9% | Mixed MCTs |
| Goat Milk | ~15% (varies) | Lauric dominant |
Pure MCT oil contains 100% MCTs, usually C8 and C10.
Are Medium-Chain Triglycerides Bad for You?
MCTs are safe for most people. They do not build up in arteries because the liver processes them quickly. Studies show no increase in heart disease risk.
Some people may experience loose stools or stomach upset if they start with high doses. This usually improves by increasing the dose slowly. Studies show no toxicity even at 100 grams per day.
People with gallbladder problems or allergies should be careful. MCTs should be balanced with other fats because they do not contain omega-3s.
How MCTs Boost Metabolism and Weight Loss
MCTs help the body burn fat instead of carbohydrates. This is why they are popular in keto diets and bulletproof coffee.
Studies show replacing LCTs with MCTs increases energy use and fat burning without cutting calories. Daily use of 30 ml MCT oil helps people reach ketosis faster and reduces keto flu symptoms.
MCTs reduce appetite by increasing fullness signals. People who use 1–2 tablespoons daily often report steady energy and fewer cravings.
Brain Boost: MCTs and Cognitive Power
The brain uses a lot of energy. Normally it uses glucose, but MCTs provide ketones as an alternative fuel.
Studies show MCTs increase blood ketones and help stabilize memory in people with mild cognitive impairment. Long-term studies show many Alzheimer’s patients maintained or improved mental scores with regular MCT use.
Healthy adults also benefit. Small doses improve focus, and older adults report better mental well-being when combining MCTs with light exercise.

Fuel for Workouts: MCTs in Athletic Performance
MCTs help athletes improve endurance without digestive discomfort.
They increase energy production in cells and reduce fatigue. Studies show MCTs help maintain performance during long workouts like cycling and running.
Athletes should start with small doses to avoid stomach issues during intense training.
Smart Ways to Use MCT Oil Daily
MCT oil can be added to coffee, smoothies, salads, or low-heat cooking. It has a smoke point above 320°F, so it is not suitable for deep frying.
Dosage should increase slowly:
Day 1: 1 teaspoon
Build to: 1–2 tablespoons daily
Maximum: 4–7 tablespoons if tolerated
MCTs help with ketosis, weight management, and digestion problems like poor fat absorption.
Potential Downsides and Who Should Avoid MCTs
Too much MCT oil may cause diarrhea, gas, or bloating, especially for beginners or people with IBS. These effects usually reduce as the body adjusts.
Rare reactions include cramps or allergies. Pregnant or breastfeeding women should consult a doctor. People with liver conditions should monitor intake carefully.
MCTs work fast but do not replace essential fats found in long-chain oils.
Backed by Science: Key Studies on MCTs
Research over many years supports the benefits of MCTs. Studies show improved energy use, gut health, and metabolic support.
Recent studies show MCTs help muscle balance in seniors and may improve insulin sensitivity in people with type 2 diabetes.
