Fat Eliminator contains a revolutionary new form of chitosan called LipoSanULTRA. Chitosan"s abilities as a natural fat binder have been known and used for years. It can literally bind with dietary fats making them nonabsorbable, thus allowing our bodies to pass them through instead of entering into our system. This, of course, is amazing. Chitosan proved to be a very successful dietary supplement for years by people trying to lose weight and control their fat intake.
