The
Glycemic Index and Dieting |
by:

The
field of nutrition is awash with charts,
tables, diagrams, models, acronyms, and
abbreviations; more than the average person
can memorize. As such, one often comes across
someone who has simply burnt out trying
to keep track of how much to eat, when to
eat it, how to find the calories from fat,
the RDI, the DV, and so on. There is an
overkill of useful information within the
nutrition field, and it can ironically provoke
one to grow weary and exhausted, tune out,
and go grab a fast food burger.
Yet every once in a while, a concept within
the nutrition field emerges that truly demands
attention. Over a decade ago, the USDA’s
“Food Pyramid” was one such concept because
it helped eaters discover how many gaps
existed in their typical daily diet. Now,
as the Food Pyramid begins to take a new
shape, and as the nutrition field works
to establishes itself as the most important
branch of health care in the 21st century,
an invention called the Glycemic Index is
taking center stage.
The Glycemic Index (GI) is not new; it has
been around for more than 2 decades. Yet
until recently, its exposure beyond the
world of diabetes has been limited [i].
The Glycemic Index indicates how “high”
or “low” blood sugar levels change in response
to carbohydrate intake. A “high” Glycemic
Index indicates carbohydrates with a swift
breakdown, whereas a “low” Glycemic Index
indicates carbohydrates with slow, gradual
breakdown. Both terms are of equal importance
to diabetics, because there are times with
high Glycemic Index foods are required,
and times where low Glycemic Index foods
are required.
Indeed, the Glycemic Index itself is not
new, but its application far beyond the
borders of a diabetic dialogue is notable;
especially for dieters.
People striving to lose weight often face
a nemesis much tougher than establishing
an exercise regimen or introducing healthier
foods into their diet. The problem is one
of energy. Many dieters are surprised –
and disturbed – to learn that their diet
program is causing them to lose more than
inches and pounds: they are losing energy.
This is often expressed as a complaint,
as in “I’m feeling weak”, or even “I can’t
stay awake”. Many dieters and those advising
them have erroneously chalked this up to
a matter of attitude, or will power, or
some non-biological cause.
The plain truth is that many dieters have
been oblivious to the Glycemic Index, and
hence, to the fact that many of the diet
foods they have eaten – or are eating right
now – score very high Glycemic Index levels.
As such, these foods are providing a quick
boost to blood sugar levels, and then setting
up the dieter for the inevitable fall. This
is because high GI foods typically increase
blood sugar values, which in turn trigger
the hormone insulin to clear sugar from
the blood. Since blood sugar (a.k.a. glucose)
largely dictates the body’s energy levels,
it stands to reason that this process manifests
as an initial boost in energy, and then
as a depletion of energy. This rise and
fall of blood sugar – and energy – is often
described by dieters using a “roller-coaster”
analogy: one minute they feel confident
and strong, and the next, they are about
to pass out and require some kind of stimulant
in order to make it through the day.
Regrettably for many dieters, that stimulant
is usually more high Glycemic Index foods,
such as sugary snacks or soft drinks. It
is easy to see how this experience can lead
an individual to stop dieting. After all,
before the diet, the individual was merely
gaining weight. On the diet, the individual
is gaining weight and is exhausted for most
of the day. It is better to quit the diet.
The above scenario only takes place, however,
when a dieter unwittingly eats high Glycemic
Index foods. Research has shown that low
Glycemic Index foods, which raise blood
sugar levels much more gradually than high
Glycemic Index foods, are very helpful for
dieters [ii]. This is because a dieter will
experience less of a “roller-coaster” ride
while on the diet, and furthermore, will
be less inclined to snack because energy
in the form of blood glucose is being released
slowly and gradually. Low Glycemic Index
foods are much more efficient sources of
energy than high Glycemic Index foods, because
the body needs less insulin to convert food
into energy [iii].
Despite the growing awareness that low Glycemic
Index foods are beneficial, the world of
diet foods has not kept pace. This is because
many manufacturers are searching frantically
to find low Glycemic Index carbohydrates
sources for their products, and overlooking
a basic, simple fact: the lowest possibly
Glycemic Index is no carbohydrates at all.
These zero-carbohydrate/zero sugar nutritional
supplements – which are quite rare in the
market – do not deliver any sugar to the
bloodstream. As a result, dieters do not
have to worry about riding the “roller coaster”
of energy spikes and pitfalls.
Yet there is an even greater benefit for
dieters who choose a ‘zero sugar’ nutritional
supplement. If that low Glycemic Index nutritional
supplement is rich in complete protein,
then it will act as a sort of antidote to
high GI foods by helping to combat their
adverse consequences.
For example, a dieter who eats a high Glycemic
Index candy car can mitigate the roller-coaster
spike in blood sugar levels by eating a
nutritional supplement that has very low
Glycemic Index and has a rich source of
complete protein. This is because the protein
in the nutritional supplement mixes with
the high Glycemic Index of the candy bar,
and effectively lowers the overall Glycemic
Index. This is welcome news to dieters who
would otherwise be seeing those extra carbohydrates
transformed by insulin into triglycerides,
and stored in adipose tissue; also known
as body fat.
Currently, only a handful of nutritional
supplements are designed to offer zero carbohydrates
and thus score as low as possible on the
Glycemic Index. And of these zero-carbohydrate
products, even fewer offer a rich source
of complete protein that effectively helps
counter the blood sugar spike impact of
high Glycemic Index foods.
It is inspiring to note that Glycemic Index
is getting some well-deserved attention
from outside the diabetic community, where
it has helped millions of people eat wisely.
Now, dieters and obese people can enjoy
the wisdom that this index promotes.
