MCT Oil Weight Loss Results – 2 Fit Doc’s Put MCT Oil to the Test

MCT Oil has piqued the interest of many people in the diet and weight loss world, so we decided to put it to the test. In this article, we share our MCT Oil weight loss results, and some other discoveries we made about using it.

MCT Oil Weight Loss Results

Here at 2 Fit Doc’s, we use Dr. Keith as our guinea pig. We designed a high-fat/low-carb/high-fiber diet for him to follow, and we have been tracking how it has been working.

In this video, Keith shares his experience using MCT oil to accelerate fat loss.

How MCTs Work for Weight Loss & Energy

MCT oil is an oil made up of medium-chain triglycerides or MCTs (Medium-Chain Triglycerides).

Triglycerides are fat molecules in your body. Basically, they consist of three fatty acid chains hooked to a glycerol molecule.


The fatty acid chains of a triglyceride can be short, medium or long in length, and each one is handled differently by your body.

The unique thing about medium-chain triglycerides (MCTs) is that when you eat them, they go directly from your digestive tract to your liver where they get immediately converted into energy.

Because they are turned into energy, there’s very little left to get stored as body fat.

So, in theory, MCT oil provides us with dietary fat that does not get turned into body fat, and instead, boosts your metabolism.

That’s a pretty big promise, so we wanted to put MCT oil to the test.

MCT Oil Experiment – Putting It to the Test

We set up an informal experiment using Dr. Keith as our guinea pig. While we are the first to acknowledge that this MCT oil experiment was far from scientific, we feel that the results are worth sharing.

Keith started taking three teaspoons of MCT oil each day. This amount was spread over three cups of coffee that he consumed throughout the morning.

Our test went for 25 days and here are the MCT Oil Weight Loss Results:

Over the course of 25 days, Keith lost 6.6 pounds (3kg).

That is a good amount of weight loss, but we cannot say that using MCT Oil accelerated his weight loss.

  • His average daily weight loss during the trial was 0.26 pounds per day.
  • His average daily weight loss for the 25 days prior to the trial was 0.35 pounds per day. (8.8lbs (4kg) total)

It is important to note that we did not control important variables. For instance…

At the time of the experiment, Keith had only been on his accelerated plan for eight weeks. It is typical to see greater weight loss early on a low-carb diet due to water loss.

Also, we did not keep his nutrient breakdown (i.e. the percentage of fat, protein, and carbs) completely consistent throughout the trial.

Conclusion: MCT Oil Weight Loss Results

While we can’t say that our informal test of MCT Oil accelerated weight loss, it may have helped Keith’s body continue to lose weight during a time period when weight loss tends to slow down.

We can also say that MCT Oil has helped Keith keep his fat content up. The high fat intake helped his body move into ketosis, which is an important part of his diet strategy.

Keith is following a high-fat, high-fiber, low-carb diet. One of the reasons he is following this type of diet strategy is because he was prediabetic and insulin resistant and research points to this type of diet as being effective.

In fact, in 2015 there was an important review study published in the Journal Nutrition that took a comprehensive look at all of the research out there and showed conclusively that a low-carb, high-fat diet was best for treating prediabetes and diabetes (1).

Is MCT Oil Worth Taking?

Based on the results Keith got from taking MCT oil and the research that supports the positive health benefits of using this oil, Keith has decided to continue using MCT oil in his diet on a nearly daily basis.

As the other half of 2 Fit Docs, I (Dr. Becky) want to add that I’ve also started using MCT oil to help maintain my weight loss.

I’m 50 years old and at this age, it’s hard to find an advantage, MCT oil has been a great addition to my diet. I only use one teaspoon in my morning coffee, for now, I don’t know that I’ll be adding any more or not.

Overall, I feel good taking MCT oil, and I feel that it has helped my energy and mental clarity. I also think it may have helped to reduce my hunger and sugar cravings.

Overall, MCT Oil Gets a Thumbs Up

In our opinion, MCT oil gets a thumbs up and I think you will be seeing more about this unique oil in the future.

But there is a warning to heed. A spike in the popularity of a product often leads to a rush by companies to put their brand on the market. This rush of competition can lead to low-quality brands.

We did our homework and compared brands. The one we use is Left Coast MCT Oil.
