Re: How do fat 'trappers' work?

I don't know that the body has specific compounds that "trap" fat and allow
the body to store the fat.  There are compounds that transport fat from the
intestine where dietary fat is absorbed and from the liver where fat is
synthesized to the rest of the body.  These compounds are called 
chylomicrons and very low density lipoproteins (VLDL).  Both chylomicrons 
and VLDL are very efficient at transporting the fat.  Some of the fat from 
these 2 compounds is used by muscles and organs (like the heart) for energy 
and some of it is stored in the adipose tissue.

There are some medications and some dietary supplements that claim to 
function by trapping fat and preventing its absorption in the intestine.  
These compounds are taken orally and then have their effect in the 
intestine.  The medication is available by prescription and is only 
appropriate for people who are seriously overweight.  The dietary 
supplements are available over the counter, but should be used with the 
realization that they may have side effects.
