I just wish they would do a low-carb version. I tried soylent for a couple of weeks and had my annual physical and my blood sugar level was much higher than it has been in the past. So much so that my doctor asked me what I had been doing and what I was eating. He said I was now suddenly "pre-diabetic." I stopped soylent immediately.
As a side note, I now have four boxes of soylent for sale if anyone wants them... :)
