i'm on a waiting list.. i made my order about 1 1/2 months ago and don't expect to receive it until the end of the year at the latest. the guy behind soylent is more of a techy type and less a business man. choosing the name "soylent" is kind of a bad idea since that word is synonymous with the movie about people eating/drinking other people.
but yeah, there are some videos of people who have tried soylent and only soylent for extended periods of time.. i don't remember where the video was from, probably youtube, but the guy who did it was actually healthier at the end of his trial. oh and he lost some weight and had more energy.
i might cancel it since a 4-6 months delay after charging me $70 is not justified. basically they are taking my money to invest, while i wait patiently for 6 months. communication has been poor and updates on estimates are not posted very often.
yes, i know of soylent green. it's not very smart to name your product after a movie like that, but the ingredients are listed on the package, and people have reported positive results from using it (including a few who had their health checked before and after going on a soylent-only diet for weeks). overweight people have lost weight, and by most accounts, people have more energy throughout the day.
