The lighter life one was in the news a while back. It actually has to be done under doctor supervision as the only way to get the 'food' for it is through a prescription and the participant has to be morbidly obese I believe. The reason it was on the news is people have been selling their 'food' on ebay where people with EDs have been buying it for large sums of money and people have been making quite a profit. It was a plea for people to stop selling it. The whole situation is a fantastic exampleb of how people will exploit each other
