Three ways MCT Oil Aids Weight-Loss

July 9, 2023 5 mins to read

MCT Oil is best known for it’s ability to boost energy, improve memory and reduce risk of neurodegenerative diseases like Alzheimer’s and Dementia. But MCT oil can also be an effective tool and supplement you can add to your diet, to promote weight-loss. In this article we quickly outline what MCT Oil is, and how it specifically helps with weight-loss.

What is MCT Oil

MCT oil, or Medium-Chain Triglyceride oil, derived from coconut or palm oil, is a type of fat (or lipid) that’s more easily digested and quickly converted into energy, when compared to other fats. When consumed, MCTs are swiftly transported to the liver, where they’re converted into ketones providing an immediate and direct energy source for all the cells that make up your body. This unique metabolic process, combined with the feeling of satiety it provides, can potentially support weight management and may enhance cognitive function when included as part of a balanced diet.

How MCT Oil helps with Weight-loss

Much of the research I’ve come across on MCT oil and weight-loss comes from Dr. Steven Gundry…He puts MCT oil in a class he labels “Mito-Boosters” or Mitochondrial boosters, which provides energy to enhance mitochondrial function – the powerhouses of your cell used for virtually every single cellular process that goes on in your body. He also states they are one of the best compounds to activate what he refers to as the “Caloric Bypass Switch”….Next to polyphenols like Resveratrol and Grape Seed Extract, MCT Oil is one of the most powerful Mitochondrial boosters.

Increased Energy Expenditure

MCTs are unique types of fat which are more easily absorbed and rapidly metabolized in the liver, bypassing much of the normal fat digestion process. This rapid metabolism of MCT Oil leads to increased energy expenditure, essentially burning more calories than long-chain triglycerides (LCTs), which are found in most other foods.

Ketones & Mitochondrial Function

The body can obtain ketones in 2 primary ways: through a ketogenic diet or, to a lesser extent, by supplementing with MCT oil – when MCTs are metabolized in the liver, they can be converted into ketones, which provide an immediate and direct source for cells (including brain cells) and cellular function. When the cells in your body have energy via ketones, they can function better, which can help with the complex processes involved in things like fat storage.

Helps feel Satiated

Some research suggests MCTs may improve feelings of fullness vs LCTs (Long Chain Triglycerides) and part of that is the Ketones they produce, when metabolized by the liver. Another reason may be MCTs ability to influence the production of hormones like leptin and peptide YY that promote feelings of fullness. If you feel fuller then it could help reduce your calorie intake, because most people stop eating once they feel full.


These are just 3 ways in which MCTs Aid in weight-loss, although there may be many more lesser known mechanisms. When it comes to weight-loss, everyone has different things that work well for them…many people often find they regain the lost weight after a diet, because many diets are restrictive and unsustainable. I tend to be more practical with making small dietary changes that over-time have a huge impact on weight-loss. MCT Oil is cheap, and readily available practically anywhere (like costco), so it’s an easy item for people to pick up and add to their daily tea or coffee, to help improve their energy, memory and promote healthy weight-loss, that sticks.

Holistic Weight-loss

It should be noted that MCT Oil should be taken as part of a healthy diet (such as a ketogenic or custom diet), designed to help you lose weight. In addition combining diet and supplementation as part of a holistic (whole health) plan that involves physical activity, adequate hydration and mental health support – are all vital components in your weight-loss journey. You can hire me as your weight-loss professional by booking a Nutritional Consult (online to anywhere in the world via Zoom Video Call) and we can get you started on a custom holistic weight-loss plan that makes you feel healthier and happier, while ensuring success.
