"I've put on 40 pounds in one year!" "It doesn't matter how much I workout, I can't lose weight." "My doctor must think I'm eating pizzas in the closet."

With nearly 4 million Americans weighing in at over 300 pounds, is it any wonder the above cries are heard each and every day by countless frustrated people who can't lose weight? One such cause for the ever increasing need to buy larger pants is a disease known as Syndrome X.

Syndrome X is also referred to as Metabolic Syndrome, Metabolic Syndrome X and Insulin Resistance. It is a very common disease; however it is widely overlooked by many medical professionals. One statistic reveals 1 in 3 people suffer from it.

This syndrome is a precursor to developing Diabetes Type 2. Sufferers have a high level of insulin. Their bodies are unable to process all the insulin that is being made from their diet. As a result, they become insulin resistant.

Think of it like this: You knock on someone's door because you want to come in. If they don't answer, what normally happens? You knock again, right? Sometimes you may even knock a third time, trying to gain entry. Insulin works in the same manner. The pancreas produces insulin (knock). Some foods cause the body to produce even higher levels of insulin (knock again). Once you become insulin resistant, develop Syndrome X, the body is unable to properly process the glucose, therefore the pancreas tries to make up for it by producing even more insulin. It thinks "no one is home" and just keeps making more.

The main purpose of glucose is to be used as fuel for the cells in the body to produce energy. Unprocessed glucose translates into fat. If the body keeps making it and it's not being processed, where does it go? Hips, thighs, stomach, and buttocks, that's where!

In addition to hypertension and heart disease, elevated insulin may be associated with weight gain and difficulty with weight loss, other blood sugar problems such as hypoglycemia, and some menstrual related imbalances.

Genetics is partially responsible for causing this disease. More likely though is lifestyle. In many cases years of high starch, processed foods, simple sugars, lack of exercise, smoking, and increased stress may be the culprit for Metabolic Syndrome X.

Now what? For starters, start exercising today. Increase water intake and totally omit starches, sugars, processed foods from your diet. Limit or omit caffeine. Try to maintain at least one third of your daily food intake to vegetables. Ask your doctor to test your sugar levels. Change what you're eating and get walking and you'll be amazed at the pounds start to fall off. The fatigue and fuzziness will start to disappear and in turn you'll feel much better.
