| Proteins are the
basic building blocks of the human body. They are made up of amino
acids, and help build muscles, blood, skin, hair, nails and internal
organs. Next to water, protein is the most plentiful substance in
the body, and most of it (around 60% to 70%) is located in the skeletal
muscles.
There are 20 amino acids that
are required for growth by the human body and all but eight can
be produced in an adult body. These eight amino acids are called
essential amino acids and must be supplied to the body by food
or supplements. The other twelve non-essential amino acids are
manufactured within the body, but both essential and non-essential
amino acids are necessary for the synthesis of tissue proteins.
What does all this mean? It means that if you don't supply your
body with the essential amino acids it needs, the amount of protein
your body can use for building muscle is limited.
Foods that contain all of the
essential amino acids are called complete proteins. These foods
include beef, chicken, fish, eggs, milk and just about anything
else derived from animal sources. Incomplete proteins do not have
all of the essential amino acids and generally include vegetables,
fruits, grains, seeds and nuts. So, if you're a vegetarian, does
this mean you can't get complete protein? Not at all. Below is
a chart listing some incomplete proteins. To get all of the essential
amino acids, simply choose foods from two or more of the columns.

Several types of evidence indicate
that exercise causes substantial changes in protein metabolism.
In fact, recent data suggests that the protein recommended dietary
allowance might actually be 100% higher for individuals who exercise
on a regular basis. Optimal intakes, although unknown, may be
even higher, especially for individuals attempting to increase
muscle mass and strength.
So, in essence, the more you exercise,
the greater your protein needs will be.
How to Calculate Your Protein
Needs:
1. Weight in pounds divided by
2.2 = weight in kg
2. Weight in kg x 1.0-2.0 gm/kg = protein gm.
Example: 170 lb male who is a
regular exerciser and lifts weights
170 lbs/2.2 = 77kg
77kg x 2.0 = 154 gm protein/day
Example: 125 lb female who is
a regular exerciser and lifts weights
125 lbs/2.2 = 57kg
57kg x 1.30 = 74gm protein/day
Choose good carbs, not no carbs. Whole grains
are your best bet. Don't be misled by fad diets that make blanket
pronouncements on the dangers of carbohydrates. They provide the
body with fuel it needs for physical activity and for proper organ
function, and they are an important part of a healthy diet. But
some kinds of carbohydrates are far better than others.
The best sources of carbohydrateswhole grains,
vegetables, fruits and beanspromote good health by delivering
vitamins, minerals, fiber, and a host of important phytonutrients.
Easily digested carbohydrates from white bread, white rice, pastries,
sugared sodas, and other highly processed foods may contribute
to weight gain, interfere with weight loss, and promote diabetes
and heart disease.
The glycemic index of food is a ranking of foods
based on their immediate effect on blood glucose (blood sugar)
levels. Carbohydrate foods that breakdown quickly during digestion
have the highest glycemic indexes. Their blood sugar response
is fast and high. Carbohydrates that breakdown slowly, releasing
glucose gradually into the blood stream, have low glycemic indexes.In
short, the goal should be to build a good plan including the low
Glycemic Index foods. This way, hunger is minimized, and there
is less tendency to "cheat" or overeat. Consequently,
you can continue to lose body fat or maintain your weight - once
the excess pounds have been lost.
Even for those whose main objective is not fat
loss, foods that are low on the glycemic index will help alleviate
mood swings and regulate energy levels.Some points to ponder:
* Foods that stimulate insulin surges can cause
people to eat 60 - 70% more calories at the following meal.
* People who consume foods relatively high in glucose (such as
white bread, most commercial whole wheat bread, and raisins) eat
an average of 200 calories more at the next meal than those who
eat fructose (a sugar found in fruits).
Low glycemic index foods can be mixed with modest
quantities of high glycemic foods without losing their hunger
reducing effect.
The purpose of the chart is not to have you eliminate
those nutritious choices from your diet. Instead, balance the
foods that are "less desirable" by eating them with
foods that are "desirable."

Fat is an important part of a
healthy diet because it provides essential fatty acids and energy
(calories). It also helps your body absorb Vitamins A, D and E.
Fats and oils are made mostly
of fatty acids. There are four main types of fatty acids. Most
fats and oils contain a mixture of all four types, but such mixtures
usually have a higher proportion of one particular type of fatty
acid.
The four main types of fatty acids
are:
Polyunsaturated fatty acids
- Many common vegetable oils (e.g., soybean, corn and sunflower
oil), fatty fish (e.g., salmon, mackerel, smelt, herring and trout),
fish oils, flaxseed, sunflower seeds, soybeans and some nuts (e.g.,
walnuts) contain a high proportion of polyunsaturated fatty acids.
Monounsaturated fatty acids
- Olive oil, canola oil, high oleic sunflower oil, avocados and
certain nuts (e.g., cashews, pecans, almonds and peanuts) contain
a high proportion of monounsaturated fatty acids.
Saturated fatty acids -
Coconut, palm and palm kernel oils, animal fats (e.g., pork and
beef), butter, cheese and other dairy products contain a high
proportion of saturated fatty acids.
Trans fatty acids - These
are found naturally in small amounts in certain foods (e.g., dairy
products, beef and lamb). Also, small amounts of trans fats are
formed during the refining of liquid vegetable oils (e.g., canola
and soybean oil). Trans fats are also created when manufacturers
use a process called "partial hydrogenation." This process
turns liquid oil into a semi-solid form, such as shortening or
margarine.
Food products made with fats or
oils with a high proportion of saturated or trans fatty acids
have a longer shelf life than products made with oils that contain
a higher proportion of other fatty acids. Saturated and trans
fatty acids also play a role in producing the textures and flavours
that make many bakery products and snacks so tempting. For example,
it is the saturated and trans fatty acids that give pastries that
"melt in your mouth" feeling.
The best way to minimize the risk
of adverse health effects related to trans fat is to reduce your
intake of foods that contain trans fatty acids.
* Follow the suggestions in Canada's
Food Guide to Healthy Eating. The Guide advises you to choose
lower fat dairy products, leaner meats and foods prepared with
little or no fat.
* Read the labels on pre-packaged food products. Since December
2005, it has been mandatory for most foods to list on the "Nutrition
Facts" table the amount of trans fat in the product. Also,
look for the phrase "partially hydrogenated oil." If
you see this phrase in the list of ingredients on the label, it
means the product contains trans fat.
* Choose soft margarines that are labelled as being free of trans
fat or made with non-hydrogenated fat.
* Choose soft margarines that are labelled as being free of trans
fat or made with non-hydrogenated fat.
* Fry foods less often. When you do fry foods, use healthier oils
that contain a higher proportion of monounsaturated fats. Do not
re-use the oils more than two or three times.
* When you eat out, ask about the trans fat content of foods on
the menu.
Remember, saturated fat also increases
your risk of developing heart disease. You can lower your intake
of both saturated and trans fats by eating more vegetables and
fruit, fish, shell-fish and other seafood, whole grain breads
and cereals, peas, beans, lentils and nuts. It also helps to choose
oils and fats that contain a high proportion of polyunsaturated
and monounsaturated fatty acids.
Finally, help your children develop
healthy eating habits. Encourage them to eat healthy snacks that
are lower in trans fats and saturated fats, and lead by example.
Good snack choices for children include fruits and vegetables,
milk, yogourt, and whole grain cereal and bakery products that
are lower in trans fats and saturated fats
HOW
MUCH WATER?
Water is your body's principal
chemical component, making up, on average, 60 percent of your
body weight. Every system in your body depends on water. For example,
water flushes toxins out of vital organs, carries nutrients to
your cells and provides a moist environment for ear, nose and
throat tissues. Lack of water can lead to dehydration, a condition
that occurs when you don't have enough water in your body to carry
out normal functions. Even mild dehydration can drain your energy
and make you tired.
Every day you lose water through
your breath, perspiration, urine and bowel movements. For your
body to function properly, you must replenish its water supply
by consuming beverages and foods that contain water. You probably
have heard everything from 6 - 8 glasses to 4 litres of water
per day. Recent studies have shown that 8 8oz glasses of water
per day should be adequate for most people. In addition, the water
consumed in fruit, coffee, tea etc can be counted towards the
8 glasses total.
It's
generally not a good idea to use thirst alone as a guide for when
to drink. By the time you become thirsty, it's possible to already
be slightly dehydrated. Further, be aware that as you get older
your body is less able to sense dehydration and send your brain
signals of thirst. Excessive thirst and increased urination can
be signs of a more serious medical condition. Talk to your doctor
if you experience either.
SETS, REPS AND STUFF!
In order to maximize your time
in the gym/fitness center it is very important to understand the
principles of what you are trying to do. First, weight training
is progressive weight resistance using the Progressive
Resistance Overload Principle. This means you increase the
load gradually as the body adapts to the new stress. Muscles reuire
progressive increases to stimulate new growth and development,
either through weight increases or to a lesser degree repetition
increases. Growth and development is acheived through rest
and sound nutrition after proper training.
The SAID principle or
Specific Adaptation to Imposed Demand
tells us that specific adaptations occur in response to imposed
demands. When a specifc muscle is excercised in a specific manner,
it will adapt to the stress imposed upon it and little effct will
be seen in the rest of the body.
There are 4 major variables that
come into play when setting up your program. This is the FITT
Principle. Frequency: Number of sessions/week, Intensity:
Level of Exertion, Time: length of workout, Type:
type of exercise or activity. It is more benifical to ensure your
workouts are more intense than longer. You can workout hard and
you can workout long, but you can't workout hard and long!
So after all that, what is left
is to understand what reps and sets are and how many of each should
be done to accomplish what you want.
* Sets of one to five repetitions
primarily develop strength, with less impact on muscle size and
none on endurance.
* Sets of six to twelve repetitions develop a balance of strength,
muscle size and endurance.
* Sets of thirteen to twenty repetitions develop endurance, with
some increases to muscle size and limited impact on strength.
* Sets of more than twenty repetitions are considered to be focused
on aerobic exercise. They do still use the anaerobic system, but
usually at a rate through which it can consistently remove the
lactic acid generated from it.
Individuals typically perform
one to six sets per exercise, and one to three exercises per muscle
group, with short breaks between each set - the specific combinations
of reps, exercises, sets and break duration depends on the goals
of the individual program. The duration of these breaks determines
which energy system the body utilizes. Performing a series of
exercises with little or no rest between them, referred to as
"circuit training", will draw energy mostly from the
aerobic energy system. Brief bursts of exercise, separated by
breaks, are fueled by anaerobic systems.
