Hypoglycemia is a common problem. Over the past fifteen years,
our dietary establishment has made a virtual industry of extolling
the virtues of carbohydrates.
We're constantly told that carbohydrates are the good guys
of nutrition, and that, if we eat large amounts of them, the
world should be a better place. In such a world, the experts
tell us, there will be no heart disease and no obesity.
Under such guidance, Americans are gobbling breads, cereals,
and pastas as if there were no tomorrow, trying desperately
to reach that 80 to 85 percent of total calories advocated
by the high-carb extremists.
This creates a terrible paradox: people are eating less fat
and getting fatter! No medical authority will tell you that
excess body fat makes you healthier. There is but one alarming
conclusion to reach: a high-carbohydrate, low-fat diet may
be dangerous to your health.
Overeating carbohydrate foods can prevent a higher percentage
of fats from being used for energy, and lead to a decrease
in endurance and an increase in fat storage.
Eating fat does not make you fat. It's your body's response
to excess carbohydrates in your diet that makes you fat. Your
body has a limited capacity to store excess carbohydrates,
but it can easily convert those excess carbohydrates into
excess body fat.
It's hard to lose weight by simply restricting calories.
Eating less and losing excess body fat do not automatically
go hand in hand.
Low-calorie, high-carbohydrate diets generate a series of
biochemical signals in your body that will take you out of
the balance, making it more difficult to access stored body
fat for energy. Result: you'll reach a weight-loss plateau,
beyond which you simply can't lose any more weight.
Diets based on choice restriction and calorie limits usually
fail. People on restrictive diets get tired of feeling hungry
and deprived. They go off their diets, put the weight back
on (primarily as increased body fat), and then feel bad about
themselves for not having enough will power, discipline, or
motivation.
Weight loss has little to do with willpower. You need information,
not will power. If you change what you eat, you don't have
to be overly concerned about how much you eat. Adhering to
a diet of low carbohydrate meals, you can eat enough to feel
satisfied and still wind up losing fat-without obsessively
counting calories or fat grams.
Food Can Be Good or Bad
The ratio of macronutrients protein, carbohydrate, and fat-in
the meals you eat is the key to permanent weight loss and
optimal health. Unless you understand the rules that control
the powerful biochemical responses generated by food, you
will never achieve optimal wellness.
Unfortunately, many people don't really know what a carbohydrate
is. Most people will say carbohydrates are sweets and pasta.
Ask them what a vegetable or fruit is, and they'll probably
reply that it's a vegetable or fruit-as if that were a food
type all its own, a food type that they can eat in unlimited
amounts without gaining weight.
Well, this may come as a surprise, but all of the above-sweets
and pasta, vegetables and fruits-are carbohydrates. Carbohydrates
are merely different forms of simple sugars linked together
in polymers-something like edible plastic.
Of course, we all need a certain amount of carbohydrates
in our diet. The body requires a continual intake of carbohydrates
to feed the brain, which uses glucose (a form of sugar) as
its primary energy source.
In fact, the brain is a virtual glucose hog, gobbling more
than two thirds of the circulating carbohydrates in the bloodstream
while you are at rest. To feed this glucose hog, the body
continually takes carbohydrates and converts them to glucose.
It's actually a bit more complicated than that. Any carbohydrates
not immediately used by the body will be stored in the form
of glycogen (a long string of glucose molecules linked together).
The body has two storage sites for glycogen: the liver and
the muscles. The glycogen stored in the muscles is inaccessible
to the brain. Only the glycogen stored in the liver can be
broken down and sent back to the bloodstream so as to maintain
adequate blood sugar levels for proper brain function.
The liver's capacity to store carbohydrates in the form of
glycogen is very limited and can be easily depleted within
ten to twelve hours. So the liver's glycogen reserves must
be maintained on a continual basis. That's why we eat carbohydrates.
The question no one has bothered to ask until now is this:
what happens when you eat too much carbohydrate? Here's the
answer: whether it's being stored in the liver or the muscles,
the total storage capacity of the body for carbohydrate is
really quite limited.
If you're an average person, you can store about three hundred
to four hundred grams of carbohydrate in your muscles, but
you can't get at that carbohydrate. In the liver, where carbohydrates
are accessible for glucose conversion, you can store only
about sixty to ninety grams.
This is equivalent to about two cups of cooked pasta or three
typical candy bars, and it represents your total reserve capacity
to keep the brain working properly.
Once the glycogen levels are filled in both the liver and
the muscles, excess carbohydrates have just one fate: to be
converted into fat and stored in the adipose, that is, fatty,
tissue.
In a nutshell, even though carbohydrates themselves are fat-free,
excess carbohydrates ends up as excess fat. That's not the
worst of it. Any meal or snack high in carbohydrates will
generate a rapid rise in blood glucose. To adjust for this
rapid rise, the pancreas secretes the hormone insulin into
the bloodstream. Insulin then lowers the levels of blood glucose.
The problem is that insulin is essentially a storage hormone,
evolved to put aside excess carbohydrate calories in the form
of fat in case of future famine. So the insulin that's stimulated
by excess carbohydrates aggressively promotes the accumulation
of body fat.
In other words, when we eat too much carbohydrate, we're
essentially sending a hormonal message, via insulin, to the
body (actually, to the adipose cells). The message: "Store
fat."
Hold on; it gets even worse. Not only do increased insulin
levels tell the body to store carbohydrates as fat, they also
tell it not to release any stored fat. This makes it impossible
for you to use your own stored body fat for energy.
So the excess carbohydrates in your diet not only make you
fat, they make sure you stay fat. It's a double whammy, and
it can be lethal.
Insulin is released by the pancreas after you eat carbohydrates.
This causes a rise in blood sugar. Insulin assures your cells
receive some blood sugar necessary for life, and increases
glycogen storage.
However, it also drives your body to use more carbohydrate,
and less fat, as fuel. And, insulin converts almost half of
your dietary carbohydrate to fat for storage. If you want
to use more fats for energy, the insulin response must be
moderated.
Diets high in refined sugars release more insulin thereby
allowing less stored fat to be burned. High insulin levels
also suppress two important hormones: glucagon and growth
hormone. Glucagon promotes the burning of fat and sugar. Growth
hormone is used for muscle development and building new muscle
mass.
Insulin also causes hunger. As blood sugar increases following
a carbohydrate meal, insulin rises with the eventual result
of lower blood sugar. This results in hunger, often only a
couple of hours (or less) after the meal.
Cravings, usually for sweets, are frequently part of this
cycle, leading you to resort to snacking, often on more carbohydrates.
Not eating makes you feel ravenous shaky, moody and ready
to "crash." If the problem is chronic, you never
get rid of that extra stored fat, and your energy is adversely
affected.
Does this sound like you? The best suggestion for anyone
wanting to utilize more fats is to moderate the insulin response
by limiting (ideally, eliminating) the intake of refined sugars,
and keeping all other carbohydrate intake to about 40% of
the diet. Generally, non-carbohydrate foods-proteins and fats-don't
produce much insulin.
Insulin responses can vary greatly from person to person.
But generally, more refined foods evoke a stronger and/or
more rapid insulin reaction. One reason for this is refined
carbohydrates lack the natural fiber which helps minimize
the carbohydrate/insulin response.
Consumption of natural fiber with carbohydrates can reduce
the extreme blood sugar reactions described above. Low-fat
diets cause quicker digestion and absorption of carbohydrates
in the form of sugar. By adding some fats to the diet, digestion
and absorption is slower, and the insulin reaction is moderated.
Recommendations for them include long-term restriction of
carbohydrates and an increase in dietary fats. For some of
these people, it means lowering carbohydrate intake to below
40%, sometimes even as low as 20%. By moderating carbohydrate
intake you can increase your fat burning as an optimal and
efficient source of almost unlimited energy.
Perhaps a third to a half or more of our population is unable
to process carbohydrates-sugars and starches efficiently.
In many people it's due to genetics, with lifestyle contributing
to the condition.
This can be termed insulin resistance or IR. Like many problems,
IR is an individual one, affecting different people different
ways. You must determine if you are carbohydrate intolerant,
and if so, to what degree. Blood tests will only diagnose
the problem in the later stages, but the symptoms may have
begun years earlier.
As we now know, insulin has many functions. While it can't
get glucose into the cells efficiently when they're in a state
of insulin resistance, insulin still performs its other tasks,
including converting carbohydrates to fat and inhibiting stored
fat from being burned.
In a normal person, 40% of the carbohydrates eaten is converted
to fat. In the IR person, that number may be much higher.
Many people with IR have a family history of diabetes.
Don't think of IR itself as a disease, although left unchecked,
it can create problems that lead to disease. It may be quite
normal for some humans to be unable to eat large or even moderate
amounts of carbohydrates.
As a matter of fact, we evolved for hundreds of thousands
of years from the so-called cave man's diet," which consisted
solely of meat and vegetables.
With the onset of modern civilization about 5,000 years ago,
our physiology suddenly was asked to digest and metabolize
larger amounts of sugar and starch especially refined sugars.
But if we are unable to utilize the amount of carbohydrates
we eat, certain symptoms will develop.
Below is a list of some of the most common complaints of
people with IR Many symptoms occur immediately following a
meal of carbo-hydrates, and others are constant. Keep in mind
that these symptoms may also be related to other problems.
1. Fatigue. Whether you
call it fatigue or exhaustion, the most common feature of
IR is that it wears people out. Some are tired just in the
morning or afternoon; others are exhausted all day.
2. Brain fogginess. Sometimes the fatigue of IR is
physical, but often it's mental (as opposed to psychological);
the inability to concentrate is the most evident symptom.
Loss of creativity, poor memory, failing or poor grades in
school often accompany IR, as do various forms of "learning
disabilities."
3. Low blood sugar. Brief, mild periods of low blood
sugar are normal during the day, especially if meals are not
eaten on a regular schedule. But prolonged periods of this
"hypoglycemia," accompanied by many of the symptoms
listed here, especially mental and physical fatigue, are not
normal.
Feeling jittery agitated and moody is common in IR, with
an almost immediate relief once food is eaten. Dizziness is
also common, as is the craving for sweets, chocolate or caffeine.
These bouts occur more frequently before meals or first thing
in the morning. The old hypoglycemic diet, still in use today,
recommends frequent snacks, and individuals with IR usually
know to eat often. However, the hypoglycemic diet contains
too much carbohydrate for most IR people.
4. Intestinal bloating. Most intestinal gas is produced
from dietary carbohydrates. IR sufferers who eat carbohydrates
suffer from gas, lots of it. Antacids or other remedies for
symptomatic relief, are not very successful in dealing with
the problem.
Sometimes the intestinal distress becomes quite severe, resulting
in a diagnosis of "colitis" or "ileitis,"
although this is usually not a true disease state. However,
IR is often associated with true gastrointestinal disease,
which must be differentiated from simple intestinal bloating.
5. Sleepiness. Many people with IR get sleepy immediately
after meals containing more than 20% or 30% carbohydrates.
This is typically a pasta meal, or even a meat meal which
includes bread or potatoes and a sweet dessert.
6. Increased fat storage and weight. For most people,
too much weight is too much fat. In males, a large abdomen
is the more evident and earliest sign of IR. In females, it's
prominent buttocks, frequently accompanied by "chipmunk
cheeks."
7. Increased triglycerides. High triglycerides in
the blood are often seen in overweight persons. But even those
who are not too fat may have stores of fat in their arteries
as a result of IR.
These triglycerides are the direct result of carbohydrates
from the diet being converted by insulin. In my experience,
fasting triglyceride levels over 100 may be an indication
of a carbohydrate problem, even though 100 is in the so-called
"normal" range.
8. Increased blood pressure. It is well known that
most people with hypertension have too much insulin and are
IR. It is often possible to show a direct relationship between
the level of insulin and the level of blood pressure: as insulin
levels elevate, so does blood pressure.
9. Depression. Because carbohydrates are a natural
"downer," depressing the brain, it is not uncommon
to see many depressed persons also having IR.
Carbohydrates do this by changing the brain chemistry. Carbohydrates
increase serotonin, which produces a depressing or sleepy
feeling. This is the reason nice hotels place candy on your
pillow in the evening; it literally helps you sleep. (Protein,
on the other hand, is a brain stimulant, picking you up mentally.
Here's another example of how trends distort the real picture:
many people have been taught that sugar is stimulating. This
is a significant consideration for those trying to learn,
whether at school, home or work.)
10. Insulin Resistance is also prevalent in persons
addicted to alcohol, caffeine, cigarettes or other drugs.
Often, the drug is the secondary problem, with IR being the
primary one. Treating this primary problem should obviously
be a major focus of any therapy.
IR sufferers may have other symptoms as well. However, when
a person with this problem finally lowers carbohydrate intake
to tolerable levels, many if not most of the other symptoms
may disappear.
With the stress of IR eliminated, the body is finally able
to correct many of its own problems. It is possible, although
unlikely, that so many of these symptoms can be found in someone
who tolerates carbohydrates quite well.
RULES OF THE ROAD TO REACH BALANCE
1. Protein. Know how much protein your body needs.
Never consume more protein than your body requires. And never
consume less. For precise measurements our nurse can determine
that for you.
You can also perform the calculations reviewed in The Zone.
Generally adult protein requirements range from a low of 35
grams per day or a sedentary 250 pound obese individual to
as much as 200 grams per day for a lean heavily exercising
100 pound athlete.
You should have protein at EVERY meal and the total per day
should equal your daily requirement. For every three grams
of protein at a meal you need to have four grams of carbohydrate
and 1.5 grams of fat.
You can multiply protein by 1.25 to obtain the amout of carbohdrate
and by 0.5 to obtain the amount of fat. This is a rough estimate
and you should not become overwhelmed trying to get this absolutely
precise. It is important though to be in the general area.
Corrinne Netzer wrote a book The Complete Book of Food Counts
that can help you make this calculation. You might also want
to make an appointment with our diet counsellor Anne to help
you with this process.
Choose your protein based on those recommended for your blood
type. This can be found in Dr. D'Adamo's book Eat Right For
Your Type. If you are seriously ill you should have your blood
subtyped so we can provide an even more accurate recommendation
for you.
2. Carbohydrate. You should also choose your carbohydrates
from Dr. D'Adamo's book. If you are insulin resistant, (have
high blood pressure, high cholesterol, high blood pressure
or are overweight) then you need to specifically restrict
your carbohydrates based on the Heller's book The Carbohydrate
Addict's Lifespan Program.
Combining all three authors is the most powerful method we
know to lower your insulin levels and produce optimum health.
If you find yourself hungry and craving sugar or sweets two
to three hours after a meal, you probably consumed too many
carbohydrates that last meal. Whenever you have a problem
with hunger or carbohydrate cravings, look to your last meal
for a clue to the reason why.
No matter how consistently you follow this dietary strategy,
you are bound to make mistakes. This is especially true at
parties or when traveling. Remember, if you're only unbalanced
for a short period of time, you're only one meal away from
rebalancing. It's like falling off a bike-you just get back
up and continue your journey.
3. Fat. Choose your fats based on Dr. D'Adamo's recommendations.
Most people can tolerate olive oil and it is the oil of choice.
It is best purchased in small glass bottles. Fish is a good
source of EPA which is beneficial fat that will help balance
out your hormone levels and decrease inflammation.
4. Water. Try to drink at least 64 ounces of pure
water per day. If you are a heavy caffeine user, gradually
reduce caffeine intake to zero whenever possible as the breakdown
products of caffeine will tend to increase insulin levels.
5. Exercise. Try to get 30 to 60 minutes of walking
in four to five days a week if the weather permits. If you
are seriously debilitated you will have to wait until your
health improves. As you are healthier and if you are blood
type 0 or B you can shift to more aggressive exercises.
