7 Reasons to Eat More
Saturated Fat |
Mid-Section Fat Loss: Problem Solved? 
A couple of generations ago two physicians - one on the East
Coast, one on the West - while working long hours with many
patients, serendipitously stumbled onto a method to rapidly
decrease fat around the mid-section. We're sure that other
doctors figured out the same thing, but these two were locally
famous and published their methods. Interestingly, neither was
looking to help patients lose weight.
Blake Donaldson, M.D., who practiced in Manhattan, was looking
for a treatment for allergies; Walter Voegtlin, M.D.,
a Seattle gastroenterologist, was trying to figure out a better
method for treating his patients with
Crohn's disease and ulcerative colitis. Dr. Donaldson got his
inspiration from a
meeting
he had with the aforementioned Vilhalmur Stefansson; Dr.
Voegtlin came up with the same idea based on his knowledge of
comparative anatomy. Though they came at two different questions
from very different angles, they arrived at the same dietary
answer. Both solved the problems they were seeking to solve and,
coincidentally, noticed that their overweight patients lost a
tremendous amount of fat from their abdominal areas while
undergoing the treatment. As happened later with us and with Dr.
Atkins, word of their success in combating obesity spread
rapidly, and before long both physicians were deluged with
overweight patients seeking treatment, completely changing the
character of their medical practices. In retirement, both wrote
books about their methods. Donaldson's was published in 1961;
Voegtlin's in 1972. And as far as we can tell, although their
years of practice overlapped, they never knew one another.
What was their secret? What did these two men independently
discover? What kind of nutritional regimen did they use to bring
about such great results in their patients?
Both had their patients follow an all-meat diet.
An all-meat diet? 
Yes, an all-meat diet. Remember that when these physicians were
in practice, there hadn't been all the negative publicity about
saturated fat and red meat that there has been in recent years.
At that time, most people considered meat as simply another
food, just like potatoes, bread, or anything else. No one
worried about eating it. The (misguided) hypothesis that fat in
the diet causes heart disease hadn't reared its ugly head, so
telling people at that time to go on an all-meat diet didn't
provoke the same sort of knee-jerk emotions that it does - at
least in some quarters - now.
The patients who followed these all-meat diets rapidly lost
weight from their midsections and improved their blood sugar and
blood pressure problems if they had them. Calculations of
cholesterol in all its various permutations was still decades
away, but both doctors even used the all-meat diet for their
patients with heart disease without problem. The all-meat diet
proved to be a safe, filling, rapid way to help patients lose
abdominal fat while improving their health. And remember, one of
these diets was developed to treat GI problems, the other to
treat allergies. The rapid weight loss that followed was a
surprising, but welcome side effect.
7 Reasons to Eat More Saturated Fat
In the not-so-distant past, the medical establishment considered
all fats equally loathsome: all fats were created equal and
they're all bad for you. Things have changed in that quarter, if
only slightly. You have no doubt heard the drumbeat of current
medical thinking on fats: some fats are now good for you - olive
oil and canola oil* - but others are bad for you - trans fats
and all saturated fats. That's
an improvement from the old cry, but far from the truth.
It seems that no matter how the story spins from the denizens of
the anti-fat camp, one piece of their advice remains staunchly
constant: "You should sharply limit your intake of saturated
fats." The next admonition will invariably be, "which have been
proven to raise cholesterol and cause heart disease." Their
over-arching belief is that saturated fat is bad, bad, bad. 
You see with just a glance at [our suggested meal plans] that
we've included fatty cuts of meat, chicken with the skin, bacon,
eggs, butter, coconut oil, organic lard, and heavy cream in the
plan. Aren't we worried that these foods will increase your risk
of heart disease and raise your cholesterol? In
a word, nope.
In fact, we encourage you to make these important fats a regular
part of your healthy diet. Why? Because humans
need them and
here are just a few reasons why.
1) Improved cardiovascular risk factors

Though you may not have heard of it on the front pages of your
local newspaper, online news source, or local television or
radio news program, saturated fat plays a couple of key roles in
cardiovascular health. The addition of saturated fat to the diet
reduces the levels of a substance called lipoprotein (a) -
pronounced "lipoprotein little a" and abbreviated Lp(a) - that
correlates strongly with risk for heart disease. Currently there
are no medications to lower this substance and the only dietary
means of lowering Lp(a) is eating saturated fat. Bet you didn't
hear that on the nightly news. Moreover, eating saturated (and
other) fats also raises the level of HDL, the so-called good
cholesterol. Lastly, research has shown that when women diet,
those eating the greatest percentage of the total fat in their
diets as saturated fat lose the most weight.
2) Stronger bones 
In middle age, as bone mass begins to decline, an important goal
(particularly for women) is to build strong bones. You can't
turn on the television without being told you need calcium for
your bones, but do you recall ever hearing that saturated fat is
required for calcium to be effectively incorporated into bone?
According to one of the foremost research experts in dietary
fats and human health, Mary Enig, Ph.D., there's a case to be
made for having as much as 50 percent of the fats in your diet
as saturated fats for this reason. That's a far cry from the 7
to 10 percent suggested by mainstream institutions. If her
reasoning is sound - and we believe it is - is it any wonder
that the vast majority of women told to avoid saturated fat and
to selectively use vegetable oils instead would begin to lose
bone mass, develop osteoporosis, and get put on expensive
prescription medications plus calcium to try to recover the loss
in middle age?

3) Improved liver health
Adding saturated fat to the diet has been shown in medical
research to encourage the liver cells to dump their fat content.
Clearing fat from the liver is the critical first step to
calling a halt to middle-body fat storage. Additionally,
saturated fat has been shown to protect the liver from the toxic
insults of alcohol and medications, including acetaminophen and
other drugs commonly used for pain and arthritis, such as
nonsteroidal anti-inflammatory drugs or NSAIDs, and even to
reverse the damage once it has occurred. Since the liver is the
lynchpin of a healthy metabolism, anything that is good for the
liver is good for getting rid of fat in the middle.
Polyunsaturated vegetable fats do not offer this protection.
4) Healthy lungs 
For proper function, the airspaces of the lungs have to be
coated with a thin layer of what's called lung surfactant. The
fat content of lung surfactant is 100 percent saturated fatty
acids. Replacement of these critical fats by other types of fat
makes faulty surfactant and potentially causes breathing
difficulties. Absence of the correct amount and composition of
this material leads to collapse of the airspaces and respiratory
distress. It's what's missing in the lungs of premature infants
who develop the breathing disorder called infant respiratory
distress syndrome. Some researchers feel that the wholesale
substitution of partially hydrogenated (trans) fats for
naturally saturated fats in commercially prepared foods may be
playing a role in the rise of asthma among children.
Fortunately, the heyday of trans fats is ending and their use is
on the decline. Unfortunately, however, the unreasoning fear of
saturated fat leads many people to replace trans fats with an
overabundance of polyunsaturated vegetable oils, which may prove
just as unhealthful.

5) Healthy brain
You will likely be astounded to learn that your brain is mainly
made of fat and cholesterol. Though many people are now familiar
with the importance of the highly unsaturated essential fatty
acids found in cold-water fish (EPA and DHA) for normal brain
and nerve function, the lion's share of the fatty acids in the
brain are actually saturated. A diet that skimps on healthy
saturated fats robs your brain of the raw materials it needs to
function optimally.
6) Proper nerve signalling 
Certain saturated fats, particularly those found in butter,
lard, coconut oil, and palm oil, function directly as signaling
messengers that influence the metabolism, including such
critical jobs as the appropriate release of insulin. And just
any old fat won't do. Without the correct signals to tell the
organs and glands what to do, the job doesn't get done or gets
done improperly. 
7) Strong immune system
Saturated fats found in butter and coconut oil (myristic acid
and lauric acid) play key roles in immune health. Loss of
sufficient saturated fatty acids in the white blood cells
hampers their ability to recognize and destroy foreign invaders,
such as viruses, bacteria, and fungi. Human breast milk is quite
rich in myristic and lauric acid, which have potent germ-killing
ability. But the importance of the fats lives on beyond infancy;
we need dietary replenishment of them throughout adulthood,
middle age, and into seniority to keep the immune system
vigilant against the development of cancerous cells as well as
infectious invaders.
Footnotes
*We advocate the use of olive oil, but recommend against the use
of canola oil, despite its widely perceived healthful
reputation. In order to be fit for human consumption, rapeseed
oil (which is canola oil) requires significant processing to
remove its objectionable taste and smell. Processing damages the
oil, creating trans fats. Also, the oil is sensitive to heat, so
if used at all, it should never be used to fry foods.
The above post is an exclusive excerpt from Dr. Eades'
newest book, which is directed at people who want to reduce
abdominal fat. Despite the title, the principles it details are
ideal for anyone who wants to decrease both visceral (internal)
and subcutaneous (under the skin) fat in the abdomen.
