My friends tell me that chitosan can help one lose weight. Is that true?

Chitosan is a health supplement widely used by people of weight loss. There are several reports claiming that this supplement can lower blood cholesterol and help one lose weight. From the few studies conducted, chitosan does appear to be more effective than a sugar pill in helping people lose weight. The weight loss is minuscule and the results are not sustained. On average people who took chitosan lost less than 8 ounces in 3 months – and that was mainly water. Best advice- walk more and eat less and get new friends.
