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.
Coconut Oil is High in Medium Chain
Triglycerides, Fatty Acids That Boost Metabolism
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%, totalling
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.
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.
