Anyone who has been in a grocery store
recently knows that food companies are
tripping over themselves in the rush to
introduce "low carb" versions of everything
from bread to candy to soda to cereal.
Do not think for a minute that these companies
are motivated by the health interests
of consumers. The reality is that they
are mainly concerned with the wallets
of consumers and will market anything
that they think a gullible public will
buy. Low carb junk food is still junk
food.
I know some of you reading this may already
be raising your defenses because you have
lost weight by cutting your carb consumption.
Let me first congratulate you on your
weight loss, and secondly say that this
is not an anti-Atkins or anti-South Beach
piece. This article is simply meant to
educate readers on the reality of carbohydrates,
"good" carb choices vs. "bad" carb choices,
what they do, why your body needs them,
and how to make better nutrition choices
than food company marketing efforts want
you to.
The first thing to understand is that
carbohydrates provide the body with its
main source of fuel, glucose (blood sugar),
which is stored in the muscles and liver
as glycogen. Any muscle contraction, whether
during exercise, getting out of bed, or
blinking an eye, is fueled primarily by
glycogen. So, for those of you engaging
in resistance training, this should immediately
point out the fact that you need carbs
for fuel in order to maximize your efforts
in your resistance program. The next fact
to understand is that your brain (which
burns more calories than any organ in
the body) and nervous system can only
use glucose for energy. This is why, especially
in the early or induction phases of carb
restricted diets, dieters often feel sluggish
and less alert than normal. By cutting
out carbs, you are cutting off your brain's
main source of fuel.
Some of you are probably thinking, "That's
exactly what I want, because now my body
will need to burn fat for energy!" Yes
and no. Yes, your body will burn some
fat for energy; however it will also generate
glucose by breaking down protein stores
in the muscles, organs and other tissues.
This will severely compromise tissue growth,
repair, and maintenance, and as discussed
in previous articles, slow down your metabolism.
Certainly, that is not the result you
are looking for.
As I said, this is not an anti-(insert
your favorite low-carb guru here) piece.
But, the truth is, carbohydrates are a
nutrient, and a nutrient is defined as
a "substance that an organism must obtain
from its surroundings for growth and the
sustainment of life". So, does it make
sense to follow a program that calls for
the wholesale abandonment of vital nutrient?
Of course not. What is needed is an understanding
of the difference between supportive,
quality carbohydrates that provide essential
nutrients and fuel, and overly processed
and refined carbohydrates that provide
empty calories and support fat storage.
What do I mean by overly processed and
refined carbs? Think about white bread,
donuts, muffins, pastries, white rice,
candy, sugary breakfast cereals, white
pasta, potato chips, crackers, soda. Foods
like these digest very quickly and give
your body a rapid spike in blood sugar,
which, when fat loss is the goal, is something
we want to avoid. After your body takes
the blood sugar it needs to replenish
muscle glycogen, whatever is left over
from that spike will get stored as fat.
What makes supportive, quality carbs
different? They digest more slowly, producing
a more gradual rise in blood sugar and
providing a more even source of fuel.
Look for breads and cereals made from
whole grains, pasta made from whole wheat
flour, brown rice instead of white rice,
sweet potatoes instead of white potatoes,
fruits in moderation and vegetables in
abundance. Whole grain carbs will keep
you feeling satisfied longer, and not
looking to devour a bag of chips within
an hour of eating your plain bagel.
So, the lesson is to not get taken over
by carb phobia and fill your shopping
cart up with all of the new low carb products.
Just like in the early 80's when the food
manufacturers were frantically trying
to come up with low fat versions of every
product under the sun, they are doing
the same now in order to sell more products,
not because they are concerned with your
health. Back then, consumers were tanking
up on SnackWell cookies. They are low
fat, so they must be okay right? Well,
since the low fat boom of the 80's, the
obesity rate in this country has skyrocketed.
That is not because the true culprit is
now carbs. No, the reason is because junk
food, whether low fat, low carb, or low
whatever, is still junk food.
