Chitosan weight loss supplement
Chitosan (KITE-o-san). A dietary weight loss supplement made
from chitin, a starch found in
the
skeleton of shrimp, crab and other shellfish. It has not been shown to
contribute to permanent weight loss. (See Glucomannan for real weight
loss.)
Chitosan weight loss supplement is a fiber whose fat-binding ability
is so strong that it can be used effectively to promote weight loss. The
most important health property of dietary fiber is its ability to bind
to fat molecules in the digestive system, which in turn are excreted.
Since Chitosan weight loss supplement can't be digested, the fat
absorbed is passed out of the body. Together with a low fat eating plan
and regular exercise, Chitosan is a great choice for keeping off those
unwanted pounds. Try taking 15 minutes before a meal to inhibit fat
absorption.
Fat Blockers - The active ingredient in a fat blocker weight loss
supplement is Chitosan. Chitosan has the
ability to bind fats and cholesterol before they are absorbed by the
body. Taken right after a meal, fat blockers will absorb some of the fat
from your diet and allow it to pass through. Some reports indicate that
Chitosan can absorb 7 times its weight in fat. Chitosan is a fiber
derived from the shells of shellfish such as shrimp.
Chitosan weight loss supplement
Chitosan is actually derived from chitin, a substance that is found
in the shells of crustaceans such as crabs, shrimp, and lobsters.
Supporters claim that chitosan binds fats in the stomach preventing
their digestion and absorption. While chitosan
has
been shown to decrease the absorption of fat, a person would have to
take massive amounts of it for it to be effective in weight loss.
Researcher do believe that chitosan may reduce cholesterol levels,
however, and are concentrating on this area of study rather than on the
effect of the supplement on weight loss.
Glucomannan: What Chitosan weight loss supplement should have been
Glucomannan comes from the root of the Konnayku plant and contains a
great
deal of natural fiber. It is thought to absorb toxins, binding them
before they are actually absorbed into the bloodstream. As such, it is
thought to suppress the appetite, actually expanding in the stomach.
Researchers have found that this supplement may in fact aid in weight
reduction, especially among obese patients. This substance is also
effective in reducing constipation due to its high fiber content.
What is Chitosan
Chitosan is a linear polysaccharide composed of randomly distributed
ß-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine
(acetylated unit). Chitosan is produced commercially by deacetylation of
chitin (can be produced from chitin also), which is the structural
element in the exoskeleton of crustaceans (crabs, shrimp, etc.).
The degree of deacetylation (%DA) can be determined by NMR
spectroscopy, and the %DA in commercial chitosans is in the range 60-100
%. The amino group in chitosan has a pKa value of ~6.5, thus, chitosan
is positively charged and soluble in acidic to neutral solution with a
charge density dependent on pH and the %DA-value.
In other words, chitosan is bioadhesive and readily binds to
negatively charged surfaces such as mucosal membranes. Chitosan enhance
the transport of polar drugs across epithelial surfaces, and is
biocompatible and biodegradable.
Chitosan is a Weight
Loss Supplement Fiber is frequently sold in tablet form at health stores as a 'fat
attractor': It is supposed to have the capability of attracting fat from
the digestive system and expelling it from the body so that users can,
it is claimed, lose weight without eating less. However, scientific
research suggests that these claims are likely without substance. At
best, unmodified chitosan would remove roughly 30 calories per day from
a person's diet. Using chitosan may have the deleterious effect of
rendering ineffective certain minerals found in foodstuffs and required
by the body in order to remain healthy.
