| Insulin Resistance Syndrome: A Common
Cause of Carbohydrate Cravings and Obesity
Insulin resistance syndrome (IRS) is a newly
recognized condition that also goes by the name of Syndrome X and
Dysinsulinism, and is closely related to hypoglycemia. People with
insulin resistance tend to gain weight and suffer from carbohydrate
cravings that in some cases can be quite intense. They may not feel
satisfied if they eat a meal that doesn't contain carbohydrates, and
they may find it difficult to stop eating carbohydrates once they've
started, even bingeing at times. They will also frequently
experience elevated cholesterol and triglyceride levels, and lowered
HDL cholesterol levels. HDL cholesterol is the good type of
cholesterol that offers protection against heart disease. Many of
these people also suffer from hypoglycemia, a condition that can
cause fatigue, anxiety, and shakiness if they don't eat frequently
enough.
Insulin resistance is a very common condition in the
US, with estimates of its prevalence running as high as 25%.
Additionally, those with IRS are at increased risk of developing
adult onset diabetes, high blood pressure, and heart disease.
Insulin resistance occurs when cells which would
normally take sugar out of the blood, and hence lower blood sugar,
become resistant to the action of insulin. It therefore takes more
insulin to keep a person's blood sugar in check. People with insulin
resistance syndrome will consequently have normal blood sugar levels
and elevated insulin levels.
Insulin resistance is a multi-factorial disease,
which means that people who develop this condition usually do so
because of a variety of genetic, lifestyle, and diet factors. Those
with a family history of adult onset diabetes, for example, are at
an increased risk of developing insulin resistance. Individuals who
are overweight, have a sedentary lifestyle, or eat a diet high in
saturated fat or simple carbohydrates are also at risk.
The primary treatment for insulin resistance
syndrome is a high protein, low carbohydrate diet. The most
problematic type of carbohydrate for people with IRS are the simple
carbohydrates which are found in foods such as cakes, candies, pies,
muffins, and ice cream. These foods contain large amounts of sugar,
which go straight into the blood and quickly raise blood sugar,
hence increasing the demand for insulin to bring the blood sugar
levels back down. Even complex carbohydrates such as potatoes,
bread, and pastas are fairly quickly digested and broken down into
sugars. It is therefore very important that people with insulin
resistance limit their intake of all carbohydrates. Proteins and
most vegetables, on the other hand, do not have this effect on blood
sugar. Proteins, in fact, will slow the absorption of the sugars
that come from carbohydrates and decrease their impact on blood
sugar and insulin levels.
Exercise and nutrients such as chromium, magnesium,
vanadium, and vitamin E can also be helpful in the management of
insulin resistance syndrome. All of these nutrients are required for
the proper metabolism of sugar. Exercise, on the other hand, has
direct blood sugar lowering effects. It can therefore decrease the
demand for insulin.
Most people with insulin resistance who follow the
above recommendations will find that they lose weight, no longer
crave carbohydrates, and don't experience the fatigue, anxiety, or
shakiness characteristic of hypoglycemia. They also will generally
find that their cholesterol and triglyceride levels drop, and that
their HDL levels rise, sometimes dramatically.
While not everyone who is overweight or has high
cholesterol levels suffers from insulin resistance syndrome, anyone
with these problems who doesn't respond to a standard low fat diet
and exercise therapy should be evaluated for this condition. This is
especially true if they experience carbohydrate cravings or the
symptoms of hypoglycemia. For help in determining whether you suffer
from insulin resistance syndrome, please consult with a naturopathic
physician. |
