Nutritional Basics, Part 1 - Protein

Hello everyone and welcome to another-

Energy Bulletin

You know that pesky little thing that we humans need to do at least
several times a day to stay alive? No, it's not breathing, we do
that about 25,000 times per day. No, it's that other silly thing,
you know, the one that most of us do either too much or not enough
of... Oh man, it's.... you know, that thing we do that is essential
for keeping both ourselves and our families alive and healthy?

Oh wow, I remember... It's good nutrition.

It never ceases to amaze me how little effort most people put into
something they will have to do several times a day or more for the
rest of their lives. We're talking about basic nutrition.

So why is it that so many people understand a lot more about their
car, their computer or how to sell ice to Eskimo's than they
understand about what is required to keep themselves well nourished
and working in tip top shape?

My guess is that it's just pure laziness or perhaps it's just that
most people still don't fathom, despite the continuous media
coverage over the last decade, that nutrition is often our best and
sometimes only line of defense against everything from fatigue,
cancer, diabetes, obesity, poor physical performance (including
sex), lack of concentration, heart disease, acute stress, pre-mature
aging, sarcopenia, osteoporosis, reduced immune system, poor
digestion, poor memory, cellular damage,
etc, etc, etc, etc...

The list really does go on and on and it's not just words on a page.
An estimated one third of all cancers are attributable to poor
nutrition, physical inactivity, and being overweight. That means
that at least one third of all cancers are preventable, probably
more.

Anyway, mine is not to deduce the lack, but to try and fill the gap,
when and where I can.

So let's start with something everyone should already know.

I want you to do a little self test with me. Just a quick quiz to see
where your nutritional knowledge is really at.

Go grab a pen and a scrap of paper. Ready?

#1 Name 3 sources of Protein.
#2 Which of these three items has protein in it. Egg yolk – Goats
milk – Bananas – Tomatoes?
#3 For a complete meal is fish a good sole source of protein?

Before you check your answers let's try a few harder ones.

#4 Protein is made up of 20 amino acids. Of these 20 there are a
certain number that can't be synthesised in humans and must be
ingested. These are called essential amino acids. How many of the 20
are essential?
#5 Failure to obtain even one of these essential amino acids within
your nutritional profile can have serious health ramifications True
or False?
#6 Is it possible to get enough protein from a vegetarian diet?
#7 Who needs more protein, a 20 year old male, a 7 year old female
or a pregnant woman?


Easy or no?

Let's see how you fared.

The answer to number one and two would be any animal, fruit,
vegetable, nut or grain. You see every single thing that's
considered alive, or at least was alive, has protein in it. From a
nutritional point of view we aren't concerned so much with the 'if'
but more of the 'how much' protein does it have. Generally animal
products contain more usable protein than plant sources.

The answer to number 3 of course is yes, fish is a wonderful source
of protein and is especially useful for some people who don't eat a
lot of red or other animal meats. An added bonus is you get the
wonderfully healthy omega 3 fatty acids from fish.

These other three questions where a little tuffer. Let's break these
down a little.

There are 20 amino acids that make up protein. If you can imagine a
car as a cell you would find carbohydrate as the fuel and the amino
acids as the metal frame and structure. As humans we are able to
synthesis or self produce 12 of these amino acids. These amino acids
are called non-essential. The other 8 (some say 9, but we shan't
tarry here) amino acids are 'essential' in that we must consume them
in our diets on a regular basis to ensure proper protein synthesis.

Typically, these essential amino acids are supplied by meat and
dairy products, but if those are not consumed, some care must be
applied to ensuring an adequate supply. As most vegetable sources of
protein are incomplete, meaning they can't fulfil the 20 on their
own, they need to be combined correctly to ensure the full amino
acid chain is complete. This can be done with the correct combination
of cereal grains (wheat, corn, rice, etc.) and legumes (beans,
peanuts, etc.)

The downside to any vegetarian diet is that failure to obtain enough
of even 1 of the 8 essential amino acids will incur serious health
implications and can result in degradation of the body's proteins.
Muscle and other protein structures may be dismantled to obtain the
one amino acid that is needed.

From a training point of view this can be very counterproductive to
any training program where the need for protein, in all of it's 20
amino acid glory, is essential for muscle building and repair. I
constantly consult with clients who are putting in the hours in the
gym but are actually losing muscle because their protein intake is
inadequate to the demands of the training regime.

So the big summery...

Protein exists in everything, which means if you are eating the
recommended 5-6 meals per day, you don't need huge amounts of
protein in any one sitting as long as you get the constant supply.
We aren't able to absorb huge amounts of protein in a single sitting
anyway, so if you miss meals or don't get enough protein throughout
the day, a huge T-bone steak isn't going to be sufficient in making
up the lack.

Personally, I would be too lazy to be a vegetarian because I
consider the extra time preparing and shopping for the right
combination of food too time consuming. Some would dis-agree and
that's fine. I know a few friends who do vegetarian very well. They
are however the vast minority.

I choose to eat red meat a couple times a week with fish, chicken
and eggs making up a large portion of my protein profile. Once again
the frequency of my meals means I'm never eating a huge portion of
anything. This makes digestion and bio availability (absorption) of
nutrients a lot more efficient.

I also use Juice Plus+ Complete (Meal replacement shake) because it
has a wonderful profile of vegetable proteins that are in themselves
super-heroes for your health.

Replacing meals with a shake is also a great way for me to fulfill the
small widow of opportunity needed to maximise the results of my
training by consuming carbohydrates 20 minutes post workout, then
some protein within an hour or two. (More on post workout nutrition
at a later time).

If you'd like more information on Juice Plus+ Complete then check
out www.energyclinicnutrition.net

If you'd like to source more vegetable proteins look at beans, peas,
spirulina, tofu, artichoke, broccoli, nuts, seeds, brown rice, lentils,
etc, etc... Remember it's all just a google away.

How much protein do you need? Well it's hard to get an exact figure
as most experts disagree, however a general guide would be 1 gram
of protein per kilo of body weight. Athletes, children (especially at
growth stages) and expectant mothers may go a little higher with
each case requiring special consideration.

Hope this help a little in bringing you up to speed on your lifelong
journey with nutrition ;o)

Train hard, train smart.

Cardio VS Strength Training

An     Energy Bulletin

Which one would you choose to get the results YOU want?

There are many different ways to get your body into shape. Most of
these methods of exercise are classified into two broad groups,
Cardiovascular (cardio) Training and Strength Training. Cardio and
strength training are very different yet closely related activities.

Cardio or endurance based (aerobic) training in such forms as
walking, running, bike riding or swimming, to name the more popular
varieties, can assist you by; burning extra calories for weight loss,
improving heart function, reducing cholesterol, improving recovery
after exercise, reducing your risk of diabetes and other diseases as
well as enhancing your ability to deal with stress, which we all of
course suffer from time to time.

Strength training also comes in a variety of forms. Free weights and
body weight training such as push ups and lunges are two of the more
popular styles of resistance training, while boxing and wrestling
styled sports, although less popular, will have similar resistance based
activities.

Strength training is used of course to assist the body in building lean
muscle. This building of muscle can have many different benefits to
your health and sporting performance such as; developing strength,
enhancing immune function, maintaining or improving muscle mass,
increasing bone density, improving movement function and joint
stability as well as increasing your metabolic rate or energy burned
which correlates to improved body composition. I.e. looking better
naked in a mirror, very important ;o)

What a lot of people don't realise however is that sometimes these
two different aspects of conditioning and exercise can have opposing
and sometimes adverse effects on the body. Prolonged endurance
training for example can actually depress the immune system, reduce
muscle mass, thereby decreasing metabolism, as well as possibly
causing a range of skeletal and joint imbalances through the high
repetition of movement that accompanies such sports as running or
cycling. (I have yet to meet a runner without at least a few niggling
injuries)

So when clients ask me which is the better method of exercise for their
particular circumstance, be it weight loss or sports performance, I'll
always answer, "Both of course".

Any great fitness program will have a good blend of cardio and
resistance training.

Where cardio may reduce muscle mass, a strong resistance style
program will increase it and  while resistance training is great for
building your biceps, a cardioprogram will do the same thing for
your heart.

A question that I often hear asked is "Cardiovascular exercise on
machines, such as treadmills and exercise bikes, burns more calories
than resistance training, so is it just a waste of gym time to add
strength training to your workout if you want to lose weight?"

The simple answer is "No."

Working your muscles as well as your heart and lungs can improve
your health and help you drop clothes size or improve your fitness
much faster than cardio on its own.

Research has shown time and again that regular resistance training
can increase your Basal Metabolic Rate (energy burned at rest) by
up to 15%.

That means your training a lot smarter!

As with anything in our lives, it is important to find the balance
that works for you. Find time for both resistance and cardio
training and you'll discover that your results will come far more
quickly and you'll be much more likely to maintain those hard
earned gains.

2 Secrets for Staying Lean

 

Another...

                           Energy Bulletin


 I am going to let you guys in on 2 of my trade secrets for staying
fit and keeping lean.

As most of you would know by now, I believe nutrition to be one of
the most important factors in achieving both good health and of
course achieving those all important aesthetics.

So my first fitness tip is of course a nutritional one.

I've mentioned in previous Energy Bulletins the importance of what
you eat, now I'd like to share a little secret about the best times
to eat.

Secret Number One- Whenever possible, try to train on a near empty
stomach.

I know, I know. This tends to go against a lot of what you've been
told in the past but hear me out here.

Whenever you're training you need to find a balance point as to how
much blood sugar(glycogen) you have in your system. The idea is to
have as little glycogen (sugar) in your blood as possible so that
your body isn't looking to use that as a fuel source over your
stored body fat.

Too little blood sugar however will cause a hypoglycemic state which
is basically where you're body will start stealing sugar from your
brain to feed your working muscles. Common symptoms of being
hypoglycemic is that you'll feel bloody awful(nausea, etc).

Here is a basic rule of thumb when trying to figure out how big a
gap you should leave between eating and training for maximum fat
burning results.

Heavy weight lifting- 1.5-2 hrs
Lighter lifting (includes smaller muscle groups) 2-2.5 hrs
Short duration but high intensity training 1.5-2 hrs
Endurance training (over an hour at lower intensity) 3 hrs
.
Keep in mind we are all individuals and everyone will be slightly
different but with time and a rough starting point you should be
able to find what works best for you.

Training Secret Number 2- Train in the morning or as early as
possible.

If you remember nothing else remember this. YOU DO NOT BURN FAT
WHILE EXERCISING!!!

Strange but true kids. What we do is set our metabolic rate during
exercise which basically sets the fat burning dial for the rest of
the day. This means that if you train in the morning, your metabolic
rate will be dialed up for a lot longer, thus burning far more
calories than if you were to train in the afternoon or evening.

The only exception to this rule is for those athletes that train at
a low intensity for a couple of hours at a time. Some cyclist and
runners would fall into this category.


So there you have in crew. Time your nutrition in accordance with
your training schedule and get that workout done as early in the
day as possible.

For those worriers among you, (and I know there is a few) don't
stress if your sessions are later in the day or you can't time your
nutrition perfectly with your workouts. The most important thing
is to train when you can and eat well balanced small meals
frequently.


To assist you with your results we are now offering 6:30 am classes
at Edwardstown on Tuesdays, Wednesdays and Thursdays.
