A variety of low carb
diets are out there, including diet books like Dr. Atkins New Diet
Revolution, Protein Power, The Carbohydrate Addict's
Lifestyle Plan, and many others. They all seem
to
have one thing in common - a strict reduction in
the consumption of carbohydrates. Most of the low-carb
diets in existence replace those carbohydrates with fats
& proteins.
As a general rule, a low-carb
diet is synonymous
with a high-fat and moderate protein diet. Those on
low carb diets should get at least 60-70% of their
daily calories from fat. Carbs should make up less
than 10% and in some cases, less than 5% of
their
daily calories.
As is turns out, dietary fat is not necessarily converted into body
fat. Carbohydrates, on the other hand, are readily
converted into fat by insulin. When
you eat high carbohydrate foods, the increased
blood sugar stimulates insulin production by the
pancreas. Insulin is the hormone that allows blood
sugar to be used by the cells. However, a side
effect of insulin is that it also causes fat to be
deposited, and it also stimulates your brain to produce
hunger signals, usually causing you eat more
carbohydrates.
Restricting the intake of carbohydrates puts a halt
to this cycle. When you restrict your carb intake,
your insulin levels fall and the levels of glycogen
increase. Glycogen is a hormone that causes body fat
to be burned and cholesterol to be removed from
deposits in the arteries.
If you severely restrict carbs, your body is put
into a state of ketosis - burning fat with the
subsequent production of ketone bodies in the
bloodstream. The result of ketosis is that your
blood sugar levels stabilize, your insulin level
drops, and because your body is burning fat, you
lose weight. One of the side effects of ketosis is bad
breath. Many people using a low carbohydrate diets try to drink more water and
and use sugarless mints or gum to counter this. Most
low carb plans, include long-term "maintenance"
phases.
Breaking through some of the Low Carb Confusion
At the peak of the lowcarb trend in 2004,
an estimated 44 million Americans were on a
lowcarb diet or were watching their carbohydrate
intake. About 5 million of those were taking
supplements, according to the Natural Marketing
Institute. Estimates of how much we spent during
2004 on lowcarb products vary from $1.3
billion to $2.5 billion.
Is a low
carbohydrate diet a healthy diet? Low
carbohydrate diets may take off more weight than
low-fat diets and may be better for cholesterol too.
At least three formal studies from the Dr. Atkins
diet have
been presented, and all have reached similar
results: Rather than making cholesterol soar, as
feared, the diet actually appears to improve it, and
volunteers take off more weight.
Both the food industry and the various consumer
groups have been pushing the FDA to issue guidelines
for food manufacturers using the terms "lowcarb" or
"reduced carb" in their food labeling- similar to
existing guidelines concerning labels for low-fat
products.
Under an agreement worked out with the FDA in 2001,
food makers can subtract the fiber and sugar
replacements from the total carbohydrate count and
calculate the remainder as "net carbs". Consumers
are confused by the terms "low-carb" and
"net carb"
and the new rules are expected better explain the
terms. It’s also possible that the definition of
"net carb" will change.
Americans who are considering dieting should not be
distracted by a currently fashionable concept like
diet food delivery,
or, the glycemic index. The index shows the speed at which
foods are converted into sugars in the body.
Carbohydrates are converted faster than proteins,
and backers of high protein diets and foods have
promoted their products as having better scores on
the index.
Although some research has suggested a lower
glycemic index indicates a lower risk of diabetes,
the evidence is not solid enough for all people to
base their basic eating plans upon, a government
panel decided.
Do Low Carb Dieters need Vitamins?
As the number of low carbohydrate products on the
market continues to grow, a related product is
booming—vitamins and supplements for low carb
dieters. Vitamin makers are now exploiting the
pitfalls of high-protein diets, namely that you lose
certain nutrients when you cut back on the carbs.
For example, you may be deficient in B vitamins
found in grain-based products, and in Vitamin C and
E, and beta carotene found in fruits and vegetables.
Sales of One-A-Day WeightSmart are soaring. However,
healthy diet experts generally agree that it’s best
to get your vitamins and minerals you need from
food.
Just how popular is Low Carb?
While a recent survey showed that 1 in 10 Americans
are currently on low carb diets and 25% of all
adults were limiting their carbs, an InsightExpress survey
that included a random sample of
500 people recruited over the Internet in a 48-hour
period in early July 2004 showed that 1 out of
5
Americans have tried a low carb diet.
Fact: low carb diets have helped millions
of people lose weight.
But starting a lowcarb diet can raise many
questions. It is important learn how to properly structure a
