You may have seen the name “MCT Oil” on the internet and social media these days. Some say it’s good for weight loss , while others say it’s good for energy before exercising. What exactly is MCT Oil? Is there any real benefit to using it? Or are there any risks? Let’s talk about all of this simply and clearly today.
Simply put, what is MCT Oil?
MCT Oil is a special type of oil made from a type of fat . The MCT in its name stands for Medium-Chain Triglycerides . Now, this may sound like a scientific name, but the story is very simple.
Think of the fat molecules in the foods we eat as big buses. These are called Long-Chain Triglycerides (LCT) . These big buses take a while to get into our bodies, get digested, and turn into energy.
But MCT is not like that. MCT molecules are very small, like a tricycle. Because they are so small, our bodies can digest them very easily and absorb them quickly into the bloodstream. As soon as they are absorbed, our bodies convert them into usable energy. That is what is special about MCT Oil.
What is MCT Oil made of?
MCT Oil is often made from either coconut oil or palm kernel oil. Both of these oils naturally contain MCT. 100% MCT Oil is made by separating and concentrating only the MCT portion of coconut oil using a special process called fractionation .
| Comparison | MCT Oil | Coconut Oil |
|---|---|---|
| Main content | Consists of 100% Medium-Chain Triglycerides (MCTs). | A mixture of both MCT and LCT (Long-Chain Triglycerides). The MCT concentration is low. |
| Absorption into the body | It is quickly digested, absorbed into the blood, and converted into energy. | It is digested slowly and is more likely to be stored in the body as fat. |
| Purpose of use | Used for quick energy, weight management, and to support the Keto Diet. | Used for cooking and general health purposes. |
Does MCT Oil really work?
This is the most important question. The short answer is, “We’re not 100% sure yet.” Research on this is still ongoing. But based on what we’ve found so far, we’ve got some clues.
- For weight loss: Some studies show that replacing your regular fats (LCTs) with MCTs can help you feel fuller for longer. This can help you feel less hungry and eat less. However, there is no strong evidence to support the claim that MCT oil will actually help you lose weight.
- Energy for exercise: Some research suggests that MCT Oil may provide a small boost of energy for older, weaker people. It is also thought to increase the amount of energy used by muscles . However, other research suggests that exercisers may not feel much of a difference. Therefore, further research is needed on this.
- For brain function: MCT Oil helps the body produce ketones . Ketones are a source of energy for the brain without carbohydrates. This is why some people say that drinking MCT Oil makes your brain sharper. However, unless you have a cognitive disorder, it is difficult to expect that drinking MCT Oil alone will improve your brain function in the long term.
- Fights infections: One study showed that adding MCT oil to breast milk for premature babies can reduce the growth of a fungal infection called Candida . The lauric acid in MCTs may also help heal skin infections and kill bacteria and viruses.
The important thing is that most of these are still in the research stage, so MCT Oil is not a 'magic bullet' for any disease.
MCT Oil and the Keto Diet
You may have heard of the Ketogenic Diet . It is a diet that is high in fat and low in carbohydrates ( starches and sugars). When you eat this way, your body burns fat for energy and produces ketones. When you use MCT Oil, it helps your body produce ketones faster than regular fats. This can help someone on a keto diet get into that fat-burning phase faster. Also, taking MCT Oil allows you to eat a little more carbohydrates like fruits and vegetables, which makes it easier for some people to stick to the keto diet.
How to use MCT Oil and what are the risks?
MCT Oil can be added to various foods and drinks.
- For smoothies
- For salad dressing
- For coffee
But remember, MCT Oil has a low burning point, so this type of oil is not good for deep frying.
The amount you should take depends on how well your body tolerates it. The recommended maximum is between 4 and 7 tablespoons per day. It is best to take this amount in small amounts throughout the day, rather than all at once. It is wise to start with a small amount, such as a teaspoon, and gradually increase the amount.
Risks and side effects of MCT Oil
Although MCT Oil is generally considered safe, there may be some risks and side effects.
- High in calories: These are a type of oil, so they are high in calories. Consuming too much can lead to weight gain.
- Cholesterol: Consuming too much saturated fat can increase cholesterol levels.
- Fatty liver: Taking high doses for a long time can lead to fatty liver.
- Stomach upset: If you take too much, especially in the beginning, you may experience:
- Stomach pain
- Bloating
- Diarrhea
- Vomiting
If you have a medical condition (e.g., diabetes, heart disease, liver disease), be sure to talk to your doctor before using MCT Oil.
Possible help from MCT Oil for certain medical conditions
For those with certain medical conditions, MCT Oil may be beneficial upon medical advice.
- Digestive system problems: If you have difficulty digesting fat or have problems absorbing nutrients (e.g., pancreatic disease, or if part of your intestine has been removed), your doctor may recommend taking MCTs.
- Diabetes: There is some evidence that it may help reduce body fat and improve insulin resistance in people with type 2 diabetes, but more research is needed to confirm this.
- Nervous system diseases: In people with diseases like Alzheimer's disease, the brain is unable to use glucose properly. Some experts believe that using ketones as an energy source instead may provide some relief to brain function.
- Heart disease: A keto diet containing MCT Oil can help you lose weight, which can reduce your risk of heart disease. It can also help increase your good cholesterol (HDL) and lower your bad cholesterol (LDL).
Again, all of this should be done only under medical advice. Using these as you see fit can have adverse effects.
Take-Home Message
- MCT Oil is a special type of fat extracted from coconut oil or palm oil that can be quickly converted into energy by the body.
- Although there are theories that it can be beneficial for things like weight loss and giving you energy for exercise, it has not yet been 100% scientifically proven.
- If using MCT Oil, always start with a very small amount, like a teaspoon.
- Do not use too much as it can cause side effects such as stomach upset and diarrhea.
- If you have other medical conditions, such as diabetes, heart disease, or liver disease, be sure to consult your doctor before using MCT Oil.
