Ive seen ads for fat blockers. What are they and do they work?
Typically, fat blockers contain a substance called chitosan, a derivative of shellfish and other crustaceans. When ingested, chitosan turns to a viscous gel in the stomach, binding with fat and preventing much of its absorption. While this may sound great at first, the fact is that since the fat is not absorbed, it must find an alternate route out of the body. It is not necessary nor in good taste to describe the results of undigested fat getting to areas of the intestinal tract not designed to encounter it, nor what happens as it exits.
