Ever since the Hoodia craze, people have been in overtime trying to find the next natural appetite suppressant.  It's understandable,  considering all the money that is spent yearly on diet supplements.  Americans are still looking for the easy out, no-work solution.  Maybe someday we'll actually find it.  It looks like the next thing to come along is going to be pine-nut oil.  Since they are relatively expensive to buy in the store, my guess is that somebody is going to extract something or other from it and add it to appetite suppressant pills before you know it.  I only hope that it will be more effective than hoodia.
