Understanding
Carbohydrates and the Low Carbohydrate Diet
For
your low carbohydrate diet (“low carb diet”) to
be a success, it’s absolutely critical that you understand
carbohydrates (“carbs”) and their roles, how to
select the right kind of carbohydrates and the carbs to avoid,
and several low carbohydrate diet techniques that can help
you achieve excellent results.
There
are all sorts of low carbohydrate diet plans out there that
can help you lose weight (not necessarily fat), but they are
so miserable that it’s impossible to stay on them very
long; even more difficult is keeping the results you achieved
before going off the low carbohydrate diet program.
The
primary role of carbohydrates in a low carbohydrate diet is
to supply energy for the body. Carbohydrates are important
not only for physical activities but also for maintaining
high levels of energy. Carbohydrates are the best choice for
fueling your system and promoting a healthy heart.
There
are two kinds of carbohydrates in a low carbohydrate diet,
simple and complex. Carbohydrates are found in a wide variety
of foods, including fruits, vegetables, grains, legumes, and
dairy products. Regardless of their source, all carbohydrates
in a low carbohydrate diet get broken down to a simple molecule
of sugar called glucose, which is the form of energy most
preferred by the body.
Three
types of carbohydrates are converted to glucose in low carb
diets: monosacharides, disaccharides, and polysaccharides.
The monosaccharides and disaccharides are known as the “simple”
carbohydrates, and the polysaccharides are known as the “complex”
carbohydrates.
After
these different forms of carbohydrates are broken down into
glucose, it enters the bloodstream where it is made available
to all cells of the body. When glucose levels rise, the body
responds to the low carbohydrate diet by releasing a hormone
called insulin into the blood. Phillips and Johnston, authors
of Think Light! Breaking Free from the Diet Prison (Speaking
of Fitness, Inc., 1999) do a great job of explaining insulin
and its role in the body. They describe insulin as a “glucose
doorman” that travels around the body opening cell doors
so glucose can enter and do its job, which is maintaining
proper blood-sugar levels. Without the help of insulin to
open the cell doors, the glucose molecule is just too big
to enter the various cells of the body. Inadequate amounts
of insulin cause improper metabolism of both glucose and fats,
leading to decreases in energy production and, too often,
diabetes.
Carbohydrates
and Proteins Together in a Low Carbohydrate Diet
As
mentioned, the body needs carbohydrates that can be converted
to glucose to provide energy; otherwise, your low carbohydrate
diet will not be a success. Protein’s primary role in
a low carb diet is to build and repair tissues, hormones,
and enzymes. Protein also helps to sustain the energy provided
by the carbohydrates. When on a low carbohydrate diet, it
is important to balance meals and snacks with carbohydrate-rich
and protein-rich foods together.
A
meal with carbohydrates alone often results in one becoming
hungry sooner, because glucose levels shoot up and then crash
down afterwards. This can leave you feeling tired, hungry,
and weak. When protein is included, you will not only stay
full longer, but glucose levels will stay more consistent
and you will feel energized for a longer period.
It
is important to understand how protein and carbohydrates interact
with each other in a low carbohydrate diet. Each food nutrient
is broken down at different times. Carbohydrates are digested
in about two hours. Proteins take longer to digest, and when
the two are combined or eaten together, protein slows down
digestion of carbohydrates, and energy from carbohydrates
is released more slowly. Protein actually slows down the release
of glucose from carbohydrates into the bloodstream making
your low carbohydrate diet a lot more realistic and effective.
Thus,
eating protein-rich foods with carbohydrate-rich foods stabilizes
the glucose, which could otherwise lead to hunger. This keeps
us feeling energetic and satisfied until the next meal. In
addition, when carbohydrates are used as energy in a low carbohydrate
diet, they spare proteins from being used as energy so they
can be used to build and repair tissues. For example, a meal
only rich in carbohydrates, such as soup, bread, and salad
would result in a period of hunger soon after the meal.
On
the other hand, a balanced lunch that includes a protein source
such as a chicken breast with salad will provide and sustain
energy. In other words, a meal is not a “meal”
if it doesn’t contain a lean complete protein and a
complex carb together at the same time; this is very important
to your success and low carbohydrate diets.
