Can you take mct oil during intermittent fasting?

Ah, fasting. That age-old practice of depriving oneself of sustenance for extended periods of time to achieve a perceived physical or spiritual benefit.

And if there’s one thing that seems to go hand-in-hand with fasting, it’s confusion about what is and isn’t allowed during the fasted state. One question that often arises in the land of fasting controversy is whether taking MCT oil – a supplement derived from coconut oil – will ruin your intermittent fast.

So let’s dive deep (yet still manage to keep our heads above the water) and explore just exactly how consuming MCT oil during intermittent fasting affects your body.

What Exactly Is Intermittent Fasting?

Great question! Before we can even begin to answer whether or not you should take MCT oil while intermittently fasting, we’d better have a good understanding of what intermittent fasting actually entails.

Intermittent fasting involves alternating periods of eating with periods where you don’t eat at all (or drastically limit your caloric intake). There are many different ways you could structure an intermittent fast, but some common protocols include:

  • 16/8: You only eat within an 8-hour window each day (e.g. 12pm-8pm), then abstain from food for 16 hours.
  • 5:2: For two non-consecutive days per week, consume only ~500 calories total throughout those days; then eat normally for the remaining five days.
  • 24-hour fasts: Once or twice per week, refrain from consuming any food whatsoever for 24 hours straight.

Intermittent fasting has gained popularity both as a weight loss tool as well as purportedly offering benefits such as improved insulin sensitivity and blood sugar regulation.

The Skinny on MCT Oil

MCT stands for medium-chain triglycerides, which are a type of saturated fats commonly found in coconut oil. However, MCT oil is more concentrated than coconut oil and contains no other fatty acids.

MCTs are absorbed rapidly by the liver and metabolized for energy – unlike long-chain triglycerides, which must be broken down before they can be used as fuel. In fact, consuming MCT oil has been shown to increase levels of ketones in the body – small molecules produced when fat is burned for energy instead of carbohydrates.

For this reason (and others), some people drink MCT oil specifically to help them enter ketosis faster or stay in a state of ketosis longer during certain diets like keto or Whole30.

But what does all this have to do with intermittent fasting?

The Big Question: Does Taking MCT Oil Break Your Fast?

The short answer? It depends!

Some people believe that anything aside from plain water will break your fast and prevent you from getting the full benefits associated with abstaining from food for those hours. This would mean that taking any form of supplement or even having a drop of creamer in your coffee would nullify the effects of fasting.

Others take a more lenient approach:

  • Some allow black coffee without added sugar or cream because it’s relatively low-calorie.
  • Others consume salt water (or electolyte supplements) on extended fasts because it helps offset dehydration.
  • And there are still others who argue that taking MCT oil doesn’t interfere with intermittent fasting at all.

Okay… So Who Is Right?

Here’s where we get into murky territory. There simply hasn’t been enough comprehensive research done on how different nutrients impact bodily processes during various forms health regimens like caloric restriction; let alone if these calories come strictly through food items only! Therefore many claims about whether particular things break a fast lack evidence-based proof!.

With that disclaimer out of the way, we’ll give both arguments a fair shake.

MCT Oil Fans: “It’s All Good!”

Those in the pro-MCT oil camp say that because your body processes MCTs differently than it does other fatty acids, it shouldn’t inhibit benefits associated with fasting.

MCT oil won’t trigger an insulin response (which is the main reason consuming food during a fast is generally discouraged); heck some people actually supplement this to keep their appetites down. And while taking MCT oil may result in increased caloric intake, proponents argue that those calories are still essentially serving as fuel for your metabolism just like if you consumed leafy greens!

So there ya go – not only do you get energy without wrecking your fast… but also….greens? Hey! It worked for Popeye right?

The Anti-MCT Crowd: “Not So Fast…”

On the flip side of the debate are individuals who believe any form of nutrient consumption during a fast is counterintuitive and will break its effectiveness. This goes well beyond protein powders or green veggies…or even keto-compliant edibles such as avocado. They stick by keeping purely water-based until they can consume balanced meals again.

The logic here – although somewhat controversial among much research- lacking nutritionists and wellness buffs alike – maintaining abstinence from all foods helps tap into natural cellular detoxification processes on a deeper level, powerfully supports intermittent fasting-related autophagy works; thereby increasing overall health gains drastically!


At end of day: one must understand whatever decision they make regarding consumables should be tailored towards what makes them attain their personalized health goals effectively regardless of other external factors or opinions. evaluating which process best meets individual requirements would apparently determine whether incorporating supplement-intake amongst diet regimen smart or simply sabotage said routine altogether.

After weighing the evidence (and levity), trying out different protocols recommendations/thought leaders touted; then seeing what works for you on a day-to-day basis is always the most vital determinant of success. Whether that’s drinking black coffee with MCT oil or simply sticking to water, make sure your fasting approach – like life in general- should be both as joyful &healthy as possible!
