text: is it true that cellulose adsorbs fat and reduces its assimilability degree? i've just read it in the article describing a diet based on low fat food. omg - where on earth did meshelle get her information?!    cellulose is an indigestible fiber that can be ingested. cellulose itself does not absorb fat. it passes through your digestive system relatively unchanged.  cellulose is used by many dieters because it add's "bulk" to the system and makes you feel full. it is also widely used in fiber-type laxatives (like fibercon)  there are compounds that do absorb fat - available only by prescription (the drug is called xenical and will absorb about 30% of dietary fat in the colon).  there are lots of over the counter diet aids that will claim to absorb fat (chitosan is one) but clinical trials have proven that this is an out and out lie.  they can continue to claim this in their advertising though because they are considered "dietary supplements" and not drugs. don't waste your money.  now cellulite, is another story. it's the dimpled areas on our butts and thighs. it causes by a tightening of the connective tissue the crisscrosses everyone's fat.  it is hereditary and gets worse as we age. it can be broken down mechanically by a process called endermology. (basically a big vibrating roller is massaged across the areas to break down the cellulite.
