Something to to with Diet Pills that are being sold on eBay. There was a big fuss and a call to ban them from being sold there because they should only be used in conjunction with visits to your GP.
No these aren't diet pills. They are all natural and made of oats. They are supposed to reduce your appetite throughout the day so that you don't eat as much.
Can't find a distributor for them in the U.S. though.
