The Cyclone Diet - what is it?

I’ve seen these commercials for the Cyclone Diet. Some sort of liquid that promises extreme weight loss in a short period of time - 8-10lbs in a couple of days. The small print states that you must fast or follow the inclosed diet in order to do so AND the stated results are not the norm. I’m guessing it’s some sort of laxative or diuretic. You have to chug 6 glasses a day!

Any clues?

I thought the Cyclone diet was right after you ate, you had to ride a roller coaster at Coney Island. You couldn’t keep anything down, so you lost weight.
