     One day last September, as Britney Spears was about to board a flight to Los Angeles from London, a blue

bottle fell out of her purse. She quickly put it back in, but not before the camera recorded the event. Neither

Spears nor her spokesman was willing to comment on the contents of the bottle, but the next morning London's

Daily Express published a page of pictures under the headline "EXCLUSIVE: POP PRINCESS SPOTTED AT

AIRPORT WITH POT OF SLIMMING TABLETS. " Spears was apparently carrying Zantrex-3, one of the

most popular weight-loss pills now sold in the United States. The pill, which is sold at about fifty dollars for

a month's supply, contains a huge amount of caffeine, some green tea, and three common South American

herbs that also act as stimulants (兴奋剂). It hit the U.S. market last March and has had a success that would

be hard to overstate. Millions of bottles have been sold, and during the Christmas season it was displayed in the

windows of the nation's largest chain of vitamin shops, G.N.C. (It is so highly sought after that many of the

stores keep it in locked counters.) Zantrex-3 is also sold at CVS, Rite Aid, Wal-Mart, and other chains, and over

the telephone and on the Internet. If you type "Zantrex" into Google, more than a hundred thousand pieces of

information about it will appear. At any moment, there are scores of people sell it on eBay.

     Perhaps the most interesting thing about the success story of Zantrex-3, however, is that it is far from

unique.There are hundreds of similar products on the market today, and they are bought by millions of

Americans. And though Zantrex's producer makes some exciting statements ("the most advanced weight

control compound (化合物) period"), so do the people who sell Stacker 2 and Anorex along with those who

sell Carb Eliminator and Fat Eliminator. Almost all of these compounds suggest that they can help people lose

weight and regain lost energy, and often without diet, exercise, or any other effort.
