Can Coconut Oil Help You Lose Weight?
Weight
loss is also among the list of benefits linked to coconut oil intake. As such,
many people looking to shed excess weight add this tropical oil to their meals,
snacks, and beverages, including coffee drinks and smoothies.
However,
like most ingredients advertised as a magic bullet for weight loss, coconut oil
may not be the easy weight loss solution it’s cracked up to be.
This
article reviews whether coconut oil can help you lose weight.
Why is coconut oil considered weight-loss-friendly?
While
there’s no doubt that coconut oil is a healthy fat, it’s unclear whether this popular
product is as effective for weight loss as many people claim.
Coconut
oil vs. MCT oil
The
belief that this oil benefits weight loss is mainly based on the claim that it
may decrease hunger, as well as the fact that coconut products contain specific
fats called medium-chain triglycerides (MCTs).
MCTs are
metabolized differently than long-chain triglycerides (LCTs), which are found
in foods like olive oil and nut butter. MCTs include capric, caprylic, caproic,
and lauric acid — though there is some controversy over including lauric acid
in this category.
Unlike
LCTs, 95% of MCTs are rapidly and directly absorbed into the bloodstream —
specifically the portal vein of the liver — and used for immediate fuel.
MCTs are
also less likely than LCTs to be stored as fat. Although MCTs naturally comprise
around 50% of the fat in coconut oil, they can also be isolated and made into a
stand-alone product, meaning coconut oil and MCT oil are not the same things .
Coconut
oil consists of 47.5% lauric acid and less than 8% capric, caprylic, and
caproic acids. While most experts classify lauric acid as an MCT, it behaves
like an LCT in terms of absorption and metabolism.
Specifically,
only 25–30% of lauric acid is absorbed through the portal vein, compared with
95% of other MCTs, so it doesn’t have the same effects on health. This is why
its classification as an MCT is controversial.
Also,
while some studies have found that MCT oil increased feelings of fullness and
enhanced weight loss, they used oils high in capric and caprylic acid and low
in lauric acid, which is unlike the composition of coconut oil.
For these
reasons, experts argue that coconut oil should not be promoted as having the
same effects as MCT oil, and results from MCT studies related to weight loss
can’t be extrapolated to coconut oil.
May
enhance feelings of fullness
Coconut
oil may increase feelings of fullness and enhance appetite regulation.
Research
has shown that adding fat-rich foods like coconut oil to meals
may increase stomach volume, inducing greater sensations of fullness than low
fat meals.
Some
research has also shown that eating foods rich in saturated fats may induce
greater fullness than eating foods rich in monounsaturated fats. However, other
studies have concluded that feelings of fullness aren’t influenced by fatty
acid saturation levels.
Therefore,
it’s unclear if choosing coconut oil over other types of fats is any more
beneficial for inducing feelings of fullness.
Finally,
food companies and the media routinely use MCT oil studies to back claims
regarding the fullness-promoting qualities of coconut oil. Yet, as stated
above, these two products are not the same.
What does the research
say?
Research
has shown that eating coconut oil may decrease inflammation, raise levels of
heart-protective HDL cholesterol, and promote insulin
sensitivity.
Still,
while many studies link MCT oil to weight loss, research on coconut oil’s
effect on weight loss is lacking.
Numerous
human studies have found that MCT oil consumption may promote feelings of
fullness and that replacing LCTs with MCTs may lead to modest weight loss.
But
remember, results from MCT oil studies should not be applied to coconut oil.
In fact,
only a few studies have investigated whether coconut oil can curb appetite or
enhance weight loss, and their results aren’t promising.
Effects
on fullness
Studies
do not support the claim that coconut oil can substantially decrease hunger and increase fullness
levels.
For
example, one study in 15 women with excess weight found that eating breakfast
with 25 ml of coconut oil was less effective at reducing appetite 4 hours after
the meal, compared with eating the same amount of olive oil.
Another
study in 15 children with obesity demonstrated that a meal containing 20 grams
of coconut oil didn’t induce greater feelings of fullness than consuming the
same amount of corn oil .
Additionally,
a study in 42 adults found that coconut oil was significantly less filling than
an MCT oil composed of high amounts of caprylic and capric acids, but slightly
more filling than vegetable oil.
Researchers
have concluded that results from MCT studies shouldn’t be applied to coconut
oil and that there is little evidence to support using it to promote feelings
of fullness.
Effects
on weight loss
While
many people believe that consuming coconut oil is a healthy and effective way
to shed excess body fat, there is little evidence supporting this theory.
The few
studies that have investigated the potential of this oil to enhance weight loss
have not shown promising results.
For
example, a 4-week study in 91 adults found no significant differences in body
weight between groups that consumed 1.8 ounces (50 grams) of either coconut
oil, butter, or olive oil per day.
However,
some research suggests that coconut oil may decrease belly fat. A 4-week study in 20 adults
with obesity observed that taking 2 tablespoons (30 ml) of this oil daily
significantly reduced waist circumference in male participants.
Similarly,
some studies in rodents have shown that coconut oil may help reduce belly fat.
However, research in this area is still limited.
Another
8-week study in 32 adults showed that taking 2 tablespoons (30 ml) of coconut
oil daily did not affect weight loss or weight gain, suggesting that this oil
may have a neutral effect on your weight at best.
The bottom line
Coconut
oil is not the weight-loss-enhancing wonder ingredient it’s portrayed to be,
and more research on its potential to promote fat loss and feelings of fullness
is warranted.
Nevertheless,
though it may not enhance weight loss, it is a healthy fat that can be consumed
as part of a well-balanced diet and utilized for a wealth of other purposes.
Still,
it’s important to note that like all fats, coconut oil is high in calories.
When trying to reach your desired weight, use it in small amounts to enhance
the taste of your foods while keeping your calorie intake in check.
In
general, rather than relying on single ingredients to drop excess pounds, it’s
more beneficial to concentrate on the overall quality of your diet by consuming whole, nutrient-dense foods and practicing
portion control.
