Essential Nutrition
By Bryan Payne Certified Fitness Nutritionist |
Over the years, and after working with many clients within the
realm of Fitness Nutrition and Fitness Training at PayneFitness
Health & Wellness, I have found that poor eating habits are the
leading reason for failure in attaining and sustaining optimal
fat reduction and improved body fat percentage. It’s important
to note that an individual CAN improve their health vitals
such as resting heart rate, blood pressure and heart stroke volume
if they consistently embark on a vigorous resistance and cardiovascular
training regime but, if their nutritional habits are consistently
inconsistent IE; Eat good one day, eat bad 3 days, eat good one
day, that they will struggle with substantial, sustained fat loss.
To eat good means to eat in a manner that does not promote
acute fat storage or acute muscle loss. To eat bad means to eat
in a manner in which acute fat storage occurs (fat is only stored
acutely) or to eat in a manner that promotes acute muscle loss.
There are many reasons for not following a healthy diet; I have
noticed that a lack of knowledge combined with an abundance of
misinformation, tend to be the most common reasons. With that
in mind, I decided to write this article to “demystify” nutrition
and to educate you in regard to the physiology of human digestion
and how it affects your body fat percentage and state of physical
fitness. We have learned that people learn more easily with the
use of analogies. Due to the fact that everyone is reasonably
familiar with how automobiles function, I have chosen to use them
as the “vehicle” so to speak to make this information even easier
to understand.
Due to the fact that we are bombarded with so much nutritional
information, it is very difficult to decipher whether the source
is legitimate or not. All of the information in this article was
based on clinical studies, which was learned from the successful
Registered Dietitian that administered the Fitness Nutrition Certification
that I procured.
The most common question I get is “what and when should I eat?”
There is a wealth of contradictory nutritional information available
including: eat carbohydrates or don’t eat carbohydrates; eat before
going to bed, do not eat three hours before bed, or do not eat
after 6 p.m.; combine food, or do not combine foods. It appears
that there is no end to this litany; with that said, you should
ignore the folklore, myths and hype and get your nutritional information
only from a reputable source.
Most of my clients’ and most peoples’ goals are to gain or maintain
their muscle mass and get rid of unwanted body fat. Even though
someone may think that this is mostly an aesthetic concern, the
fact of the matter is that body composition or body fat percentage
is a true measure of health as opposed to how much we weigh. We
are not too concerned with how much you weigh, and neither should
you. It may be surprising, but did you know that a pint of water
(2 cups) weighs a pound; and that you may gain or lose a pound
or more of body weight based on your hydration status and daily
fluid intake. So, your success or progress cannot be based on
your body weight alone. If I were to weigh you, have your drink
a pint of water, and then weigh you again, the scale would indicate
that you are a pound heavier. Does this mean that you are fatter?
The answer is obviously no! You will just be less thirsty, and
a pound heavier!
As you begin an exercise program, your body will start to store
more “fuel” within your muscle cells. This fuel is called glycogen,
which, simply put is many glucose or blood sugar molecules hooked
together and stored in your muscles and body cells for later use.
These glycogen molecules are so highly concentrated (thick) that
your body must also store water in your body cells along with
glycogen in a ratio of 1:3 (one molecule of glycogen to three
molecules of water). Because water weighs a pound for every pint
and glycogen also weighs considerably, your weight is sure to
increase as you increase your exercise levels, as your glycogen
and water storage increases in response to the increase in exercise.
An analogy will help to illustrate this phenomenon rather easily:
If your fuel tank is on empty and you are going on a long trip
by automobile, you will most likely fill up your tank. However,
if your tank is on empty and you are only going to the corner
store, you will most likely not go out of your way to fill up
your tank. The same is true with your glycogen storage; the more
you exercise, the more your body will begin to store glycogen
and water. We know that your car does not weigh as much when it
is empty as it does when it is full. So, does this mean that a
car “gets fat” every time you fill up the tank? Of course not!
A car has only one gas tank; the human body, on the other hand,
has thousands of cells that fill up with glycogen and water for
you to use as fuel the next time that you exercise, causing an
increase in body weight, but not necessarily as body fat. The
only way to know the difference between gaining weight of fat
and keeping or gaining weight of muscle is to track your body
fat percentage by measuring it weekly.
When looking at your body composition/body fat percentage weekly,
we must look for the following four signs:
|
• A gain in muscle and a loss in fat = you have a perfectly
designed meal plan
• A gain in muscle and a gain in fat = the meal plan includes
too many calories, probably from carbohydrates
• A loss in muscle and a loss in fat = you are eating enough calories,
but may not be eating enough protein.
• A gain in fat and a loss in muscle = you are either not eating
enough protein, not enough calories or both
|
This is why it is critical to meet with
your Certified Fitness Nutritionist (CFN) or Registered Dietitian
(RD) weekly for the first month of the program so that a “baseline”
is established in regard to how your metabolism is working and how
it reacts to the nutrition and exercise plan that was introduced and
implemented.
Typically, a month of weekly follow-ups is sufficient for making adjustments
until the correct trend of gaining or maintaining muscle while getting
rid of fat is established. Once this happens, a biweekly meeting with
your CFN or RD is adequate for ensuring that the trend continues.
Once you have reached your goals(s), you can meet once every three
to four weeks to make sure that you continue down the correct path
and/or establish a maintenance program depending on what your goals
may be. Finally, you should consult with your CFN or RD as you establish
new goals, or as your workout routine and schedule changes.
In helping my clients to achieve their goals of gaining muscle and
losing body fat, I teach them three basic rules of success that are
easy to follow no matter where their travels may take them. Before
we discuss these rules, let’s first review some basic nutrition information
as well as the mechanism by which fat is stored in the human body.
Food consist of three macronutrients (they are so called not because
of their size, but because of the amounts in which we need them),
by name they are, carbohydrates (CHOs), fats, and proteins. Whenever
we eat CHO’s they first go to the stomach where they are digested,
and then continue to the intestines where they are absorbed into the
bloodstream in the form of glucose (blood sugar or blood glucose).
As blood glucose levels rise, the body secrets insulin, a hormone
that is responsible for storing glucose in muscle and organ cells
in the form of glycogen. Normal blood glucose levels are between 80
and 120 mg/dl (milligrams per deciliter, a way of measuring glucose
concentration or “how thick blood gets”). Whenever blood glucose levels
fall below 80 mg/dl the body would react by slowing down its metabolism
to save energy. Continuing with our car analogy, it would be similar
to letting off of the accelerator pedal and turning off the air conditioning
in our car to conserve energy when we are running low on fuel. Of
primary importance to us however, is the fact that whenever our blood
glucose levels rise above 120 mg/dl the residual/extra glucose is
stored as fat! With this fact, the secret to dietary success is
to control blood glucose levels throughout the entire day as a means
of maintaining a high metabolism and therefore minimizing fat storage.
The practice of maintaining normal blood glucose levels alone will
have the secondary benefit of helping you avoid food cravings and
overeating.
Due to the fact that blood glucose control is very important in controlling
diabetes, many studies have been conducted to determine how different
foods affect blood glucose levels. One study is the “gastric emptying
time test,” which measures how long it takes for food to leave the
stomach. The reason that this is a very important study is that the
more quickly carbohydrates leave the stomach, the more quickly blood
glucose levels rise. Usually, the more quickly blood glucose levels
rise, the more effectively glucose gets stored as fat due to the larger
insulin secretions, and because of these larger insulin secretions,
the more quickly blood glucose levels drop (right after the insulin
secretion causes blood glucose to be stored), causing us to get hunger
pangs and/or cravings. Gastric emptying time studies show that the
longest time that CHOs will stay in the stomach is one hour. In contrast,
protein will stay in the stomach for two hours, and fats will stay
in the stomach for three to five hours. This is why you will find
yourself getting hungry 20 to 40 minutes after having a piece of fruit,
or some bread, pasta, rice, veggies or even some cereal. This also
explains why you feel stuffed for four hours after having a high fat
containing meal. These studies also found that when you combine a
protein with a carbohydrate, both the protein and fat contained in
the protein (since most proteins have some fat in them) cause the
carbohydrate to stay in the stomach longer (approximately three and
a half to four hours), which basically means that this will increases
gastric emptying time, a good thing because a longer gastric emptying
time also means a slow and controlled increase in blood glucose, which
lessens the chances of storing a large portion of this meal as fat
due to a quick and high increase in blood glucose followed by a large
secretion of insulin. A longer gastric emptying time also means mild
successive increases over time, as well as mild or slower successive
decreases in blood glucose levels caused by the longer time that it
takes for food to leave your stomach. As a consequence, you do not
get hungry as quickly, and are able to do away with your sweet cravings,
which are usually caused by the need to raise low blood glucose levels
after such a drop as described above occurs.
With the understanding of gastric emptying, it makes sense to eat
protein every time that you eat a carbohydrate. In this way, you will
increase your gastric emptying time, temper blood glucose swings,
and control your appetite/cravings. This brings the question, “what
is a protein?” Even today with all of the fad protein diets, some
people are still confused about the difference between a protein and
a carbohydrate. It’s actually very simple: If it walks, swims, flies,
looks back at you, or shows you its teeth if you corner it, it is
a protein. This means that even if you have a “beef” with “beef”,
you can eat chicken, alligator, bison or wildebeest; if it comes from
a plant or grows out of the ground, it is a carbohydrate. I’m pretty
sure that vegetarians and other readers are probably squirming at
this broad brush generalization. It’s true that beans are high in
protein, as are many other legumes, plants and even some vegetables.
But, in an effort to simplify things and to justify our generalization,
we have looked at the largest component of a food, and the foods are
grouped based on this component.
This means that even though a 1-cup serving of beans has 15grams of
protein, it also contains 40grams of carbohydrates – beans are therefore
deemed a carbohydrate. In an analogous fashion, although an avocado
is a fruit, because of its high percentage content of fat, it is considered
a fat. Another example of a caveat is milk, yogurt and buttermilk
which all come from cow’s milk. Even though cows are protein, there
milk products are carbohydrates due to the fact that milk has way
more sugar than protein.
Given the short gastric emptying time of carbohydrates, it is no wonder
that you can be hungry by the time that you get to the office after
having a bowl of cereal with milk, a couple pieces of toast with jam
or jelly, and a glass of OJ! These are all carbohydrates that leave
your stomach quickly and raise your blood glucose levels quickly,
which causes an insulin secretion that most likely stores everything
you ate for breakfast as fat, and in doing so, causes your blood glucose
levels to rapidly drop. You then go on without eating until 1 or 2
p.m., further slowing down your metabolism (remember, low blood glucose
levels cause your metabolism to put on the brakes), which will most
likely cause you to overeat at lunch, or if you are “disciplined enough”
and just have a salad for lunch, by the time you have dinner at around
7:30-8pm you find that you are feeling starved and cannot be satisfied
no matter what or how much you eat.
But wait! Stop! Hold the presses! You have probably heard (somewhere
along the way) that you are not supposed to eat after 6:00pm? So,
this means that you may as well go to bed hungry. Because, once you
fall asleep, you won’t need any energy will you? Actually, the fact
of the matter is yes, you will need energy while you are at sleep
to repair tissues, and to conduct many types of metabolic functions
that take place while you sleep of which muscle tissue repair is one.
All of these processes require energy. Said again, the “no food after
6:00pm” theory is another myth, fallacy and rubbish. The fact of the
matter is that the human body will do anything it takes to survive;
that is the body’s number on priority. Due to the fact that fat is
long-term stored energy, the human body will bypass burning fat in
the short term and will initiate a process called “gluconeogenesis”,
which simply means “the formation of glucose”. This sounds harmless
enough until you realize that the pathway in which new glucose is
formed is through the secretion of cortisol, a hormone that is responsible
for breaking down muscle tissue and turning it into sugar or glucose
so that you can continue to breathe, walk, talk, think, exercise,
etc. So even though you may think you are not eating, you actually
are eating – you are eating your own muscle! –muscle
loss, reduction and deterioration equates to slowing your metabolism
which equates to storing more fat. These are certainly undesirable
effects. Due to the fact that muscle weighs more than fat (muscle
takes about two-thirds less room than fat for the same weight), as
you eat your muscle you lose weight, meaning, there is no reason to
get excited about seeing lower numbers on the scale! In the worst
case scenario, your body may be entering a downward spiral of continual
fat storage and a suppressed metabolic rate…. This is something everyone
needs to seriously think about.
Based on gastric emptying studies and blood glucose control, there
have been three basic rules created to help you keep your muscle mass
and get rid of fat. Rule No. 1 is to eat every three and a half to
four hours, whether you are hungry or not. Again going back to the
car analogy, you probably would not drive your car until you run completely
out of fuel and have to call AAA or a friend to come rescue you…At
least we hope you don’t allow that to happen too often. The same applies
to your body and metabolism – you want to avoid continuously running
out of “fuel” and having a candy bar, soda pop, ice cream or chips
coming to rescue you either. The strategy and focus is to control
your blood glucose levels throughout your day as to prevent crashing
and craving cycles. Rule No. 2 – the most important rule – is to eat
protein every time that you eat a carbohydrate. But of course, we
want the protein to be low in fat. Before we get to the third rule,
let’s discuss carbohydrate servings. As blood glucose control is the
most important aspect of a nutrition and exercise program, and due
to the fact that carbohydrates are the only one of the macronutrients
that substantially effect blood glucose levels, we need to be able
to determine what an appropriate portion of carbohydrates is. In addition
to portions of carbohydrates, we must also define a portion of protein
and a portion of fat so that we not only control blood glucose levels
but that we control caloric intake as well. It’s fortunate that the
American Diabetes Association, along with the American Dietetic Association
(both are abbreviated ADA), have taken care of this for us.
There was a study conducted that determined how small of a carbohydrate
dose it would take to raise blood glucose levels by a measurable or
noticeable amount. It’s important to note that body fat is
acutely stored when your blood glucose levels shoot up too high too
fast! It turns out that it took exactly 15grams of carbohydrates to
do it. Due to the fact that the word “serving” has already been previously
used by millions of manufacturers of food products, the ADA’s could
not just redefine the word serving. The ADA’s decided to come up with
their own terminology and decided to call a 15gram serving of carbohydrates
an “exchange”. Therefore, even though an entire English muffin may
be one serving according to the manufacturer, since it contains 31grams
of carbohydrates it is considered to be two carbohydrate exchanges.
So, instead of having a cup of oatmeal every morning, you’re actually
having two carbohydrate exchanges. (1/2 cup of oatmeal = 15g of carbohydrates
or 1carbohydrate exchange) You may choose oatmeal, bread, cereal,
pasta, rice, potatoes, pancakes, muffins, etc., until you reach the
allocated/prescribed number of 30grams of carbohydrates or two exchanges
or as many as your CFN or RD recommends you have for that particular
meal. It is import to note that when we cook carbohydrates, that they
usually expand (rice triples in size, pasta, oatmeal, etc doubles),
and meats shrink approximately 20%. Due to this, we measure all foods
after they have been cooked. There is an exception to this
rule which is oatmeal. Since people have so many different ways of
making it, soggy and watery, stiff, like cement etc, we measure oatmeal
before it is cooked; in this way, it does not matter how much
or how little water
There truly are a correct number of carbohydrates, protein, and a
fat exchange’s that an individual needs per day to reach their health
and fitness goals but, it is not a one-sizefits- all 40-30-30 or 60-20-20
recommendation. Therefore, Rule No. 3 is to become aware of what an
exchange is and how many you need per day as well as
in what combination. To determine exactly how many carbohydrate exchanges
you need per day, as well as how many protein and fat exchanges to
combine them with, we really need to go through a nutritional assessment
that takes approximately one and a half hours. In this assessment,
your basic metabolic rate (BMR) will be determined. A CFN and/or a
RD can simply use a formula to estimate your BMR. This formula takes
into account your gender, present weight, height, and age. Your basic
metabolic rate will indicate how many calories you minimally need
to survive. Once your BMR is calculated, the next step is to calculate
your sedentary activity calories, in other words, how many calories
you burn being yourself. The calories/energy calculated in this measurement
does not take into account calories burned from exercise, only the
activities of daily living are considered. Once we have determined
the amount of calories spent in activities of daily living, the next
step is to determine how many calories you actually burn while exercising.
The amount is calculated using a value of calories per kilogram per
hour so that we know exactly how many calories you burn during specific
exercises, we can figure out how many calories you burn during weight
lifting, interval training, spinning, swimming or running a ½ mile
for instance. Once we have calculated all of the above calories we
then add your specific value for what is called the thermal effect
of foods, which is a measure of how many calories you burn keeping
warm and processing, digesting and absorbing your food. The next and
final step is to design an ideal meal pattern or plan for you.
A qualified Fitness Nutritionist or Registered Dietitian can put together
a sound meal plan based on all of the above data which will let him
or her know how many exchanges of carbohydrates, protein, and fat
that your body requires for optimal performance, fat riddance and
muscle maintenance/gains. The number of carbohydrate exchanges you
will be eating per day will depend solely on your weekly cardiovascular
and daily living activities – just how active you are. In contrast,
the number of protein exchanges that you will be eating per day will
depend on your body weight as well as the type of exercise routine
prescribed to you. If you already have and establish exercise routine,
the CFN or RD will take it into account to ensure that your body is
fueled adequately for the activities. Last but not least, the number
of fat exchanges that you will consume each day will be equivalent
of 15 to 30 percent of your total caloric intake. Such a balanced
meal plan will ensure that you attain your goals of gaining or maintaining
muscle mass while getting rid of body fat. |

For a quick review, here are the three rules
and things to consider:
|
|
1. Eat every three to four hours; hungry
or not!
2. Every time you eat carbohydrates, make
sure to eat them with protein.
3. Find out what an exchange is, and how
many you get per meal/day.
4. Meet with your CFN or RD weekly to
monitor your progress and make necessary changes to keep you on
track for attaining your goals.
