I seem to be seeing a lot of them lately- mostly in the newspapers - and in the American Airlines flight magazine there was a 2-page ad...even though they are from different companies the ads are very similar in their outlandish and incredible claims!
I've also seen eBay listings selling the same stuff, with other outlandish claims as:
"LOSE 10 LBS/WEEK -GUARANTEE!!"
"LOSE 88 LBS BY SUMMER GUARANTEED"
"LOSE 100 LBS WITH NEW DIET PILL"
All of these pills use the same ingredients - even though they all claim to be unique...Ma Huang/Ephedrine (which as most of us know can be very dangerous to use!); Chromium Picolinate (which, despite claims by the patent holders to the contrary, does NOT assist in weight loss and can even cause cancer and anemia in large doses); Bee Pollen, citrus, aloe vera, etc. NONE of these ingredients is proven to have any effect on weight loss.
