Reduce weight now! Ask me how? Among all other diet reducing remedies, Chitosan is also considered to be good supplement that helps greatly to reduce excess weight from the body.
Chitosan (pronounced KITE-o-san) is made of the indigestible chitin of shellfish. The supplement binds with undigested fat as it moves through our intestines before our body has the chance to absorb the fat. Both human and animal studies (including several acknowledged by reputable sources such as the Mayo clinic) show that chitosan can lower both weight and cholesterol levels.
But the Chitosan supplement usually has some side-effects  including extreme stomach ache due to

1. Failure to absorb vitamins A, D, E, and K that are fat-soluble vitamins.
2. Possible decrease in calcium absorption
3. Decrease of certain necessary bacteria in the intestinal track
4. Could affect certain medications that require fat absorption to be effective
5. Dehydration combined with chitosan can cause constipation and bowel obstruction
It gives extremely good results if you will start doing some exercise or walking along with chitosan. Also reduce your diet intake or just reduce carbohydrate or fat intake, you will get extremely beneficial results.
Chitosan may work for some people with a primary concern of the excessive calories they are getting from fat in their diet. Assess why you have this weight to lose before taking any dietary aid. You doctor can help you analyze your diet and exercise habits as well as map out a weight loss strategy that will be healthy for you.
