Coconut oil
is the world’s most weight loss friendly fat.
It contains
a unique combination of fatty acids with powerful effects on metabolism.
Several
studies show that just by adding coconut oil to your diet, you can lose fat,
especially the “dangerous” fat in the abdominal cavity.
Let me
explain how that works…
Coconut Oil is High in Medium Chain
Triglycerides, Fatty Acids That Boost Metabolism
Coconut oil
is vastly different from most other fats in the diet.
Whereas most
foods contain predominantly long-chain fatty acids, coconut oil consists almost
entirely of Medium Chain Fatty Acids.
The thing
with these medium chain fatty acids, is that they are metabolized differently
than the longer chain fats.
They are
sent straight to the liver from the digestive tract, where they are either used
for energy right away or turned into ketone bodies.
These fats
are often used by epileptic patients on a ketogenic diet, in order to increase
ketone levels while allowing for a bit more carbs in the diet.
There is
also some evidence from animal studies that medium chain fats are stored less
efficiently than other fats.
In one
study, rats were overfed with either long chain or medium chain fats. The rats
fed the medium chain fats gained 20% less weight and 23% less body fat.
Bottom Line: Coconut oil is high in Medium Chain
Triglycerides, which are fatty acids that are metabolized differently than most
other fats, leading to beneficial effects on metabolism.
How Coconut Oil Can Boost Metabolism,
Making You Burn More Calories at Rest
A calorie is
not a calorie.
Different
foods and macronutrients go through different metabolic pathways.
The
different types of foods we eat can have a huge effect on our hormones and metabolic
health.
Some
metabolic pathways are more efficient than others and some foods require more
energy to digest and metabolize.
One
important property of coconut oil is that it is “thermogenic” – eating it tends
to increase energy expenditure (fat burning) compared to the same amount of
calories from other fats.
In one
study, 15-30 grams (1 to 2 tablespoons) of medium chain fats per day increased
energy expenditure by 5%, totaling about 120 calories per day.
Several
other studies confirm these findings. When humans replace the fats they are
eating with MCT fats, they burn more calories.
Therefore, a
calorie from coconut oil is NOT the same as a calorie from olive oil or butter
(although these fats are perfectly healthy too).
Bottom Line: Many studies show that medium chain
triglycerides can boost metabolism, in one study increasing energy expenditure
by 120 calories per day.
Coconut Oil Can Reduce Appetite,
Making You Eat Less Without Trying
“Weight loss
is all about calories in, calories out.”
Even though
I think this is a drastic oversimplification, it is mostly true.
If your body
expends more energy (calories) than it takes in, then you will lose fat.
But even
though it is true that we need to be in a calorie deficit to lose weight, it
doesn’t mean that calories are something that we need to count or be
consciously aware of.
Humans are
very capable of remaining lean and healthy in their natural environment. The
obesity epidemic didn’t start until 1980 and we didn’t even know what a calorie
was back in the day.
Anything
that reduces our appetite can make us take in fewer calories without having to
think about it. It appears that coconut oil has this effect.
Many studies
on medium chain fatty acids show that, compared to the same amount of calories
from other fats, they increase feelings of fullness and lead to an automatic
reduction in calorie intake.
This may be
related to the way these fats are metabolized. It is well known that ketone
bodies (which the liver produces when you eat coconut oil) can have a powerful
appetite reducing effect.
Whatever the
mechanism is, it works. In one study of 6 healthy men, eating a high amount of
MCTs caused them to automatically eat 256 fewer calories per day.
In another
study of 14 healthy men, those who ate MCTs at breakfast ate significantly
fewer calories at lunch.
So… coconut
oil boosts fat burning (increases “calories out”) and it also reduces the
appetite (reduces “calories in”).
Bottom Line: Many studies show that people who
add Medium Chain Fatty Acids to their diet have reduced appetite and start
eating fewer calories automatically.
Coconut Oil Can Help You Lose Fat,
Especially The “Dangerous” Abdominal Fat
If coconut
oil can boost metabolism and reduce appetite, then it should help you lose fat
over the long term.
In fact,
there are several studies that support this.
In one
study, 40 women were given either 30 grams (2 tablespoons) of either coconut
oil or soybean oil for 28 days.
They were
instructed to eat fewer calories and walk every day. These were the results:
Both groups
lost weight (about 2 pounds).
Only the
coconut oil group had decreased waist circumference (belly fat) while the
soybean oil actually had a mild increase in belly fat.
The coconut
oil group had increased HDL (good) cholesterol levels, while the soybean oil
had reduced HDL and increased LDL.
In this
study, coconut oil did not cause overall weight loss compared to soybean oil,
but it did lead to a significant reduction in belly fat.
In another
study in obese men, 30 grams of coconut oil for 4 weeks reduced waist
circumference by 2.86 cm, or 1.1 inches.
There are
also other studies showing that medium chain fats lead to weight loss, reduced
waist circumference and various improvements in metabolic health.
The weight
loss effects of coconut oil appear to be fairly mild, except for the abdominal
fat.
Abdominal
fat, also called visceral fat or belly fat, is the fat that tends to lodge
around your organs and cause inflammation, diabetes and heart disease.
Any reduction
in abdominal fat is likely to have very positive effects on your metabolic
health, longevity and drastically reduce your risk of chronic disease.
These
results are far from being dramatic, but consider that all these people are
doing is adding coconut oil to their diet.
Combined
with other proven weight loss strategies (like cutting carbs and increasing
protein), all of this can add up to a significant amount.
Therefore,
coconut oil can support a healthy, real-food based weight loss diet, but don’t
expect it to work any miracles on its own.
If you’re
interested in even more research on coconut oil, then you can find a very
impressive collection of studies here.
Bottom Line: Eating coconut is particularly
effective at reducing the harmful belly fat in the abdominal cavity, which is
strongly associated with disease.
What About The Calories?
It’s
important to keep in mind that coconut oil is fat.
Fat has 9
calories per gram… and coconut oil is no exception.
Therefore,
if you are eating a fixed amount of calories and then add coconut oil on top of
that, then it’s likely to make you gain weight, not lose.
However,
most people aren’t counting calories and eating a fixed amount per day.
In these
cases, adding coconut oil to your diet will reduce your appetite and probably
make you eat less of other foods instead.
So this
really is not about adding fat calories to your diet, it is about replacing
some of your other cooking fats with coconut oil.
It’s also
important not to go overboard and think you need to add tons of coconut oil to
your diet to reap the benefits. The studies above used about 30 grams per day,
which equals 2 tablespoons.
Even if
coconut oil is good for cooking and has some powerful health benefits, your
diet should still consist primarily of whole, nutritious foods like plants and
animals.
