Chitosan: Where did it come from?

Regardless of chitosan's miraculous overview, it is a very simple substance which has been around for ages. It is taken from chitin, a polysaccharide found in the exoskeletons of crustaceans. It is processed by removing the shells from shellfish such as shrimp, lobster, and crabs. The shells are then ground into a pulverous powder. This powder is then deacetylated, or basically stripped of specific chemical groups which allows the compound to thus actively "soak up fats." Or so this is what the producers claim. It has been used in the past in the process of detoxifying water. It was simply spread over the surface of water, where it would immediately absorb any toxic substances such as greases, oils, or dangerous heavy metals. The process is so complete that a scum forms over the surface of water and is then easily removed. For this reason, chitosan is extremely popular all over the world in water purification plants. The present form of chitosan has just been introduced recently as a weight loss supplement.

How It Works

Let's now take a look at exactly what is chitosan and how it is used for weight loss. The allegations of how chitosan works are as follows. However, note that there is no significant studies to thus back up this information or to explain exactly how such procedures take place. Basically stated, chitosan is a special fiber which is able to "soak up" or absorb anywhere from six to ten times its weight in fat and oils. In substance, it is chemically similar to the plant fiber, cellulose. However, chitosan is able to significantly bind with fat molecules and convert them into a form which the human body does not absorb. 
It claims to affect the fat prior to it reaching the stomach and thus the fat never has a chance to be metabolized. It prevents the absorption and storage of fat by converting into a gel which "traps" the fat. In some sort, it creates a "grease ball" from this excess fat, which is too large to be absorbed by the body. It thus becomes an inert substance and is excreted in the stool. Chitosan fiber is unlike other fibers in that it carries a positive ionic charge. Since lipids, fats, and bile acids all possess negative charges, there is a chemical bond between the two and thus they attract naturally to one another.This unique ability is what makes chitosan so remarkable. This amazingly "too good to be true" ability is also what causes suspicions to arise on the validity of these claims. .

Benefiting Weight Loss

Besides from the obvious effect that fat is not absorbed into the body with the presence of chitosan, it goes a lot deeper in benefiting weight loss. Chitosan is a 100% natural and acts as a super fiber. Thus, supplementing the diet with chitosan, is part of creating a cleansing process which is said to be extremely vital to weight loss. Take note that these are again the simple declarations made by the producers of chitosan and are supported with no background studies or thus medical proof of any sort. Another stated advantage of chitosan comes from the idea that the chitosan-bound fat leaves the intestinal tract without ever entering the bloodstream. Exactly how this process takes place is not clear and seems to be somewhat far fetched. If this indeed is possible, then the point is made that there would be no caloric value and no matter how much chitosan a person takes, the caloric count remains zero.
The producers of chitosan-based products also try to claim that since a person taking chitosan continues to eat some sort of fats and is able to continue eating these types of food, the body does not crave such fattening foods nor is it starving or feeling any added sense of hunger. By supplementing chitosan into one's diet, there is less fat that the body accumulates. With less fat entering the body, the body turns to previously stored body fat to burn up. This shifts the energy source from your diet to your stored body fat and results in a net reduction in that fat - and in your weight.Obviously, the allegations are extremely pleasing, now whether or not they actually could be a reality is another side to these claims.
