By Leonid Kim MD
Summary
## Key takeaways - **Visceral Fat: The Dangerous, Easy-to-Lose Fat**: Visceral fat, packed around internal organs like the stomach and liver, drives chronic conditions such as diabetes, fatty liver disease, heart disease, and cancer. Despite its dangers, it is the easiest type of fat to lose once targeted effectively. [00:08], [00:27] - **Carotenoids: Your Visceral Fat's Genetic Switch**: Carotenoid-rich foods, like colorful vegetables, act as antioxidants that reduce inflammation and disrupted metabolism. They can turn on fat-burning genes and quiet down fat-storing genes, leading to reduced visceral fat in as little as eight weeks. [00:56], [01:34] - **Green Tea: A Kakan Powerhouse for Fat Regulation**: Green tea, rich in kakans, boosts fat oxidation and energy expenditure while inhibiting fat absorption enzymes. Studies show that drinking kakan-enriched green tea for 12 weeks significantly reduced visceral fat. [02:43], [03:38] - **Exercise: Superior for Visceral Fat Loss vs. Diet**: While diet aids total body weight loss, exercise has superior effects on reducing visceral fat. Even moderate-intensity exercise, like two 45-minute cycling sessions weekly, can drastically cut visceral fat and improve insulin sensitivity without significant scale changes. [04:34], [04:46] - **HIIT & Vigorous Aerobics: Top Visceral Fat Burners**: Vigorous intensity aerobic exercise and high-intensity interval training (HIIT) are the most effective for visceral fat reduction. Consistency is key; the best exercise is the one you can stick with at a moderate to vigorous intensity (70-80% max heart rate) for at least 45 minutes, 2-3 times per week. [06:33], [07:56]

You can lose a lot of weight and still
be stuck with belly fat. And that's
because abdominal fat isn't just under
your skin. It's also visceral fat that's
packed around your internal organs. So,
it's packed around your stomach and your
liver and your pancreas. And this is the
fat that drives a lot of the chronic
conditions that are slowly killing us
today. So, visceral fat is what drives
diabetes and fatty liver and heart
disease and even cancer. But the good
news is that while visceral fat is
dangerous, it's also the easiest fat to
lose once you know how to target it. So
in this video, I want to show you the
fastest way to specifically target
visceral fat and how to burn it off
quickly. So we're going to go over the
best foods and drinks to incorporate
into your regimen. And then I want to go
over the best exercises that will give
you the biggest bang for the buck. So
let's start with food because what you
eat every day either feeds your visceral
fat or it stars it. And one of the most
powerful weapons against visceral fat
are carotenoidrich foods. And
carotenoids are just natural pigments in
plants. They're what give carrots their
orange color and that's what makes
tomatoes red and that's what gives
spinach that dark green color. But it's
not just the color. Carotenoids are
powerful antioxidants. And that's
important because so much of what causes
visceral fat is energy excess that
eventually leads to inflammation and
disrupted metabolism. So carotenoids
reduce that stress by neutralizing free
radicals or it's these unstable
molecules that just damage cells. And by
removing free radicals, carotenoids help
you stabilize your genes. And
specifically, carotenoids can actually
help turn on genes that burn more fat.
And they actually quiet down genes that
tell your body to store fat. And there
was an interesting study that was a
randomized double blind trial in Japan
that looked at whether carotenoid intake
affects visceral fat. And what they
found was that just eight weeks of
eating carotenoid rich vegetables reduce
visceral fat, especially the group that
was randomized to the high lycopine and
low luteine group, which in that study
consisted of carrots and shabuki
cabbage. But I want to emphasize all
four groups that ate carotener rich
vegetables lowered their visceral fat.
So, how do you get these carotenoids
from your diet? Well, just target your
favorite colorful vegetables. So, things
like carrots and sweet potatoes and bell
peppers and spinach and squash, you name
it. Any colorful vegetable or fruit is
likely to be rich in some type of
carotenoid and it will help you lose
your visceral fat. Now, after
carotenoids, another special compound
that you need to target is kakans. And
these are flavonoid polyphenols which
also act like antioxidants and they
reduce inflammation. Now my favorite way
to get kakans is by drinking green tea.
And you hear it all the time, green tea
burns fat. And it does. And it does so
because it's rich in kakans. These
compounds basically change how your body
handles fat and specifically visceral
fat. And kakans help with fat regulation
in so many different ways. So first
kakans boost your fat oxidation and
energy expenditure. So they stimulate
the nervous system just to burn up more
fat and boost your overall metabolism.
And on top of that kakans also inhibit
fat processing enzymes like lipase. So
they block fat that we eat from being
absorbed in the first place. And the
reason green tea is so powerful is green
tea also contains caffeine which can
work synergistically with kakans to
enhance that fat utilization or fat
burning. And there was a double blind
placebo control randomized trial in
Japan that showed that just 12 weeks of
drinking kakinenriched green tea which
was about 600 mg of kakans per day
resulted in a significant reduction in
visceral fat. Now just remember most
green teas are high in kakans but to
really maximize the benefit you want to
target green teas that are minimally
processed. So those would be matcha or
cena teas. Now in the grand scheme of
things anything that leads to an energy
deficit or a calorie deficit will help
you lose weight and it will help you
lose visceral fat. But targeting these
right foods and drinks will help you get
there much faster. And once you've
dialed in the right foods, the correct
exercise regimen will become that
magical multiplier. In fact, the correct
type of exercise is a big must when it
comes to losing visceral fat quickly.
And we have studies like this meta
analysis of 117 studies that show that
even though both diet and exercise can
reduce visceral fat, diet has a larger
effect on total body weight loss, while
exercise tends to have superior effects
on reducing visceral fat. And there's an
older but a very interesting study that
showed just how powerful small dose of
exercise can be. So in this study, just
two 45minut cycling sessions per week at
75% of the V2 peak for 2 months reduce
visceral fat by 48%.
So almost half in just 2 months. And not
only that, but this group also improved
insulin sensitivity by 41% and lost 18%
of subcutaneous fat. And this wasn't
strainous exercise by any means that
they had to do twice a week. What they
did in the study was they measured the
intensity as V2 peak as opposed to V2
max. So, it's hard to tell exactly what
75% look like for that average
participant. But since the people in the
study were likely not professional
athletes, I assume their V2 peak was
lower than their V2 max or zone 3 range
or about 70 to 80% of maximum heart
rate. So this exercise would actually
put them in the low moderate intensity.
It's that intensity where you can still
hold the conversation and speak in full
sentences, but you just sound a little
winded. And another interesting trend
that we see from those studies is that
the total body weight stayed about the
same. So remarkable changes in dropping
their visceral fat and improving their
insulin sensitivity even though there
are no measurable changes on the scale.
And this is such an important point that
I always talk about with my patients. Do
not get discouraged if you're doing all
the right things when it comes to
nutrition and movement and proper
exercise, but the weight is just not
coming off. More often than not, the
scale is a pretty poor indicator of your
progress because the number on the scale
does not necessarily show the changes in
your body composition and loss of fat
mass. Now, what's the best type of
exercise that will help you lose
visceral fat and it will help you do it
fast? Well, a recent systematic review
and meta analysis that looked at 84
randomized control trials showed that
it's the vigorous intensity aerobic
exercise and highintensity interval
training or HIT that are the most
effective exercise modalities for
reducing visceral fat. And resistance
training was still beneficial, but just
not as effective when looking
specifically at visceral fat reduction.
And that's not to say forget about
resistance training. In fact, resistance
training is a must for maintaining your
muscle mass, and it's important for your
overall health and your metabolism. But
if you want to lose visceral fat fast,
like over the next few months, it's
probably better to dial up your cardio.
Now, if we're choosing between HIT and
aerobic exercise, there really isn't a
big difference between the
effectiveness. The studies that look at
direct comparisons show that both
modalities are very similar with no
statistically significant difference
between the two in adults. Now, if you
really want to dig into the data and the
literature, there may be a small signal
that when it comes to hit exercises, you
may get a little bit more effectiveness
with running as opposed to cycling. And
there's some studies that show that in
kids and young adults under the age of
24, HIT may be more effective than
aerobic exercise. But honestly, we're
just splitting hairs at this point. At
the end of the day, the way I see it, it
doesn't matter if you do high intensity
interval training or if you do aerobic
exercise or whether for cardio you
choose to do cycling or running or
rowing or dancing. The best exercise is
the one you'll actually stick with
because consistency beats the perfect
plan every time. So that textbook
perfect hit protocol that you just dread
and you only do twice a month is always
going to lose out to that walk that you
enjoy and are able to do several times a
week consistently. And the ideal
protocol, at least based on the studies
that are available, would probably be an
exercise that you can do at least two to
three times a week for at least 45
minutes each. And whatever you choose,
it just has to be at least moderate to
vigorous intensity, meaning you're
getting your heart rate to about 70 to
80% of your maximum capacity. And if
you're not into measuring or tracking
your heart rate, a good rule of thumb is
to do a talk test. You know you're doing
a moderate intensity activity if you can
talk in full sentences, but you sound a
little out of breath. And you know
you're doing vigorous intensity exercise
if you can only speak in a few words
before pausing and taking a breath. And
the beautiful thing about exercise is
the fact that the effects that you get
are dose dependent. Meaning the more you
do, the better are the results. There
was a recent study in the British
Journal of Sports Medicine that showed
that participants who exercise more or
with higher intensity frequently saw
proportionally greater reductions in
visceral fat. And by contrast, they did
not see that dose dependent response
with caloric restriction or dieting.
Meaning there's a limit to how much you
can restrict your calories and you
really don't see any additional benefit
after a certain point. So you do not
need to starve yourself to lose belly
fat. Quite the opposite actually. get
enough calories that still keeps you in
a small calorie deficit, but you can
gradually step up your activity and
exercise if you want to lose your
visceral fat faster. All right, I hope
this was helpful. Stay healthy and I'll
see you in the next
