Published in 1982, Patent US4344424 is the perfect diet for people who are suspicious of the drug companies and all of those wonder pills. Also for people that lack that ability to stop themselves from eating – especially those who sleep walk and raid the refrigerator. The only drawback is that you have to have someone else around who can unlock you when it is time to eat, and then you may get into a fight if they decide to lock you back up after two bites. Of course, one flaw in this invention is that you could still eat milkshakes or anything else that could be consumed through a straw. Oh and one word of advice to the guys out there - do not buy one of these for the wife or girlfriend!
